I just purchased a used 2006 GT, previous owner says fuel pump is bad. I'm sure this video will prove to be a big help getting it running again! Thank you for your time and effort!
Standing ovation!! Thank you so very much for sharing your knowledge. I watched other videos but yours is the most thorough and helped me get my 05 mustang going again. My problem was the green wire going to the inertia switch was only sending 2 volts. I pulled up the carpet to track the wire and there was my issue. The wire was damaged. I disconnected the battery and did a little wire trimming, a little wire splicing, a little wire tucking and my mustang fired right up. Thank you for the amazing video. You saved me a lot of money.
You saved my sanity, sir. Jacked up my Mustang to do some work and it wouldn't start when I was done, Yep, it was the inertial shut off switch. Pushing the reset solved the problem. Much thanks!
You're a lifesaver! My 2008 Mustang GT ran out of luck, and the trunk harness was not returning the ground, so the pump was not injecting fuel. It will need to be replaced, but in the meantime, I was able to "fix" it and go home without leaving the car in the mall parking lot. You rock!
This video was super helpful I actually had two of these issues happen I had to change the fuse that I didn’t know about underneath the dashboard and then my inertia switch triggered when I hit a bump after I had figured that out thank you for the amazing help with this video you saved me a lot of time and money
Such a great help my mustang all of a sudden shut off checked codes, got fuel preasure switch and temp. Changed then out. No luck but I had no idea mustang had the fuel shut off switch pressed it and bam got it working thanks dude!
Fantastic video, really shows how the power flows from the engine to the fuel pump. It helped me realize that my issue has to do with the wiring going from the fuel pump to the instrument cluster or something on that line. I have the P0463 error code, so it seems the info from the fuel pump is sending an error.
@@edforthewin8574 I ended up swapping out the entire Smart Junction Box. The fuse box up under the dash on the passenger side. I swapped out just about every other part on the circuit he goes over in this video. Including both fuel pumps. Hopefully yours is an easier fix.
One of the greatest videos ive seen, well done. but what would cause power to not get from the diode fuse to the relay? i tested the diode fuse, its good, the diode fuse pin has power but it isnt going to the relay?
Early troubleshooting on my daughter's 2006 mustang. I'm trying to confirm that fuel is flowing. The car runs rough and dies if you try to give it any acceleration. How can you confirm fuel is being pumped? Can you hear the fuel pump when it is running? Where can you check fuel flow? Sorry if these are novice questions.
WELL EXPLAINED,, THANKS.. Just FYI, by definition of "ground " there is no ground the vehicles because they are not directly connected to ground. In fact they always connected to the negative of the battery. I might be wrong, but a new definition for "ground" needs to be defined for vehicles that are not connected to ground.
In automotive applications, the chassis and frame are a common ground and most often connected to the negative terminal of the battery. Circuits are often utilizing a ground that is not directly connected to the battery negative terminal but instead grounded to a frame or chassis.
Having issues with fuel level indicator. Car starts fine, runs, but shortly after starting, the fuel gauge goes to empty and the cel comes on. Replaced the fuel pump 3 times. Have not used a motorcraft pump, only aftermarket. Driving(no pun intended)🤣me crazy!!
I have an 05 mustang GT, I’m not getting any power to fuse 47, which I’m told controls multiple things. Including the AC clutch relay, just got a new compressor and I’m trying to get my AC kicking. Any idea why I wouldn’t be getting power?
Do you know where the turn signal relay is? Doesn't show in both fuse diagrams. I got the issue where my front left turn signal won't light up or flash but has brand new bulb.
Would a bad fuel pump on 2005 v6 mustang cause high fuel pressure. I switched out fuel pump relay, fuel pressure sensor, and fuel filter. At idle it’s 60 psi and giving it gas not full on but increasing rpm’s it’s hits 75+ psi which is where the initial p0193 code was in freeze frame (75.9)
No fuel from pump. Tested power from relay, bit nothing at inertia switch. Does wire go directly to the olinertia switch? Or go through the ecm? Green yellow seems yo go to ecm. Am I correct?
I have a question about p0182 code would this be mostly be low voltage I have replaced the fuel pressure sensor and new fuel filter and new evap purge valve and new vent valve by the charcoal canister I have a new fuel pump module coming I also have checked the fuse box blocks wiring under the hood the wires on fuel pump fuse box Block looks good but did have the high speed fan wire that is burnt about to fix this next thank you 2005 mustang gt
My friend, I’m working on a 2006 and keeps cutting off. Sometimes runs for a a couple minutes sometimes 15 seconds and cuts off. I changed the regulator and the fuel control module in the truck and keeps doing the same. The trip safety button is fine, any ideas?? Thanks
This really helped me to understand how the fuel pump circuit works and even though I have a 2002 Mustang GT 4.6L 2V, I assume it works the same way. Here is my problem and hoping you can help me with my problem. I got a bad load of gas (14 gal.) and I need to drain the tank but I can't just siphon it out due to the anti-siphon device in the filler neck so I looked around on TH-cam and found that I can jump the fuel rely, attach a hose at the fuel rail to a gas can and just turn the key to the on position and the fuel pump will run allowing me to pump the tank down. Of course my 02 has a CCRM and the fuel rely is in that device and I can't just pull the rely so I will need to access the wiring harness and setup a splice of some kind so I can do the jump. I have checked the wiring diagram and found one for the 4V but not for the 2V. Once again, I assume they are the same Color Coded wires. Can you give me any ideas or suggestions to accomplish this. I have done some wiring in the past but not very comfortable doing it without verifying the wires I will be jumping. In fact, I plan to make a jumper that has a 20 or 30 amp fuse in it just in case. I would be grateful for any help you can give me on this!
I fixed my gauge cluster to see if that would fix the fuel gauge but it’s still doing the same thing when it reaches half a tank the needle moves to E then jumps up to the middle mark. Don’t know what else to do or check
Question- if I’d like to disable fuel pump with rocker switch - I could cut and tap into green wire under inertia switch and bring ON wire back into green wire - and that way to connect/disconnect power from fuel pump relay easy?
i wish you would do one that showed the inside of the fuel tank showing the crossover tube. im not getting any fuel from the passengers side fuel tank pumped into the drivers side. anyone know how this system works some say there is a jet pump that pumps fuel from the passengers side where the sending unit is to the drivers side. dam split tank thanks ford
I swapped my fuel pump to a deatschwerks pump and placed it into the stock sending unit now my car runs out of fuel with 4 gallons in the tank does anyone have any idea why this could be? Thanks,
Hey this is a long shot and not sure if you figured out the solution to the DTI error code. I’ve bee man having the same issue and i had my fuses, relay, and fuel pump switched out, however the problem still is occurring. From what i been reading online it seems the DTI error could could be tied up to the fuel sending pump aka the pump located on behind the passenger seat. Removing it and doing a simple test with a multi meter can let you know if that is where the issue is at. Also testing the cables the go connected to both pumps can be a cause of the issue as well. Finally there is the instrument cluster that could also be a culprit. However for that one I’ve been told it’s recommended to go to the shop as it’s very sensitive. I haven’t had time to work on car however i hope this information helps you if you haven’t already found a solution to that problem.
On my car when i turn the key to the on position the fuel pump is not working. It only does this when it is 50 degrees outside or lower. When the outside temperature is hotter i don't have any problems with it. What is your assessment about that kind of problem?
I have the lever arm that’s on top of the fuse panel in the kick panel on the passenger side but not the fuse panel under that. Any idea if any modes came without this or does that mean mine has been relocated?
Great video....Ive been trying figure mine out for while thought is was pcm issue why im getting incorrect voltage to the fuel rail pressure sensor. So i have power going to fuel control module key, on the outside black wire is ground that goes to fuel pump i have nothing no ground. Where does that ground come from? And how do i get it grounded so the fuel pump has ground on black wire? Currently with key on at fuel pump pink has power 12.3 volts, green and black has 11.3volts, black(ground) nothing, and then theres a blue with green strip no power/33 ohms when mm set on ground (red light on mm on) Update: Read ground at fuel pump only comes on on initial key on. This i have a can hear fuel pump for 2 seconds on key on. So back to fuel pressure sensor high input. Signal Reference, Sign Volt, Pressure nd Temp. Signal Reference is 0 Volts, other 3 have confirmed suppose to 5Volts mine is 5v, 12.3v, 11.3 volt. Reason for high input. Remove fuel pump relay all voltages goes to normal 5v which is correct. What could be issue with fuel pump relay switch in high voltage to fuel pressure sensor?
Hey, thanks for an amazing video, I have a problem with my 06 Roush, where I checked the relay, all fuses and diods, also I’m receiving 12 volts and a ground on that fuel pump connector when key is turned, (2 pins positive and 2 negative), but my brand new pump that i just bought doesn’t prime and doesn’t work , just like the old one that I have replaced. Could it be an ifs switch? If I’m getting the power on the connector, also what else could it be? I took the assembly out again and when connector that receives power is plugged in to the assembly i tested the pump with voltmeter and it gets no power (assembly is also brand new) , thanks for your time reading this, but I’m really frustrated and confused
Shit man I just changed my 05 V6’s fuel pump today, same shit. Brand new assembly, connected everything as it was, no priming I don’t think. Gonna check fuses tomorrow morning cause I just found this video but let’s see I guess... I’ll lyk if I find anything
Esjee I solved my issue, so my fpdm was bypassed from the previous owner through the relay that was getting power through the battery and also from the switch when you turn your key into on position, and that relay was bad, just check your fusses , relay, and wires with voltmeter , this video shows actually all the things needed , unless someone did the same bypass as on my car
I have a good one on the fuel level sensor will not pick up anything i have changed everything and blew all the hoses so I have loss 4 1/2 gallons out of the tank so my question is where does it gets power and why would it not pick the passenger side at all
Hello I have a Mustang GT 2006 and I have problem we fuel pump I ready check all the realy and all fuse too but I think is the model o broke let me know if can be the that thanks
What if your fuses are fine, relay good, but the Pressure Sensor looks like it may be bad. What is actually bad is the harness power connector that plugs into the Pressure sensor on the fuel rail . Does anyone know the ID of the four wires.???
ok, well i have been having a problem like this for a year. The car starts strong and runs great ! it is pumping about 40 lbs... then after a few minutes it slows the pump to 20 lbs and then the car stolls. I have changed fuel pump , injectors , engine, intake , O2 sensors, the part in the trunk, the relay in the fuse box, and it still does it . I am going to change out the inetia switch next... will let you know how that goes..
Lehew I need help bro. Please. My 06 mustang gt and I got the p0690 code. Car starts and runs. But it’s running crappy. I have mods and a tune. Is there somewhere I can check for like relays I switched the diodes no change?
Honestly very impressed. Very few videos like this on here. Thank you

I sent you an email with my vin. Thanks!
excellent video!!
I have 3 o2 sensor codes but I already replaced all 4 with Bosch, and codes come back. I believe it’s a fuel problem. How can I diagnose the culprit?
Did you find out? Mine did the same and it was a bad egr valve and the codes never came back.
if my fuel pump connector is receiving power but I do not hear the pump turn on when i turn on the car, does that mean its a forsure dead fuel pump?
@@tylerskellenger2313 Sounds like it
Check ground as well
Would have been nice to see the same wiring flow for the fuel gage circuitry.

Wow. You can unplug a connector better one handed, than I can with two hands and a helper.
We replaced every part that you pointed out in this video and my 2006 Mustang still act like it is out of gas
