Just a quick update, my truck is still running quite well, but on occasion, I get a "check engine" code for either the crank or cam sensor. When this happens, the truck returns to the crank, no start issue, HOWEVER, it will start again if I clear the code. I've talked with a few DODGE specialist, and they've all said my timing chains or guides might be worn. If they are, the cam and crank sensor on this motor will have a small communication issue, and will trigger the engine light. So, to fix the issue, I'm going to replace the chains and guides soon (within the next few weeks).. I love the truck, it does a nice job as a little workhorse and does nice off road. A little work on it here and there is worth it to me.
I just replaced the motor in a 2003 just like this. The truck was running when it died, (slung a rod) and we saw the new motor run before it was removed from the donor truck. The PCM (ECM)? seems to be the most likely problem. This video reinforces my theory. Thanks.
Check the cam and crank sensors and make sure they're good. If one or both are bad, this truck will NOT start. It will crank all day long, but will not fire. If those check out as good, look to the PCM. I've seen a few videos on them where the connectors can also give you headaches, but they are also quite known for the pcm failing. Good luck, let me know what you find out with yours..
Thanks, ,,my 1999 just turned 100,000 and was running rough today, then would not start again the rest of the day. Check engine light on, code says Misfire ... duh ... time for a tune up.
Thank you my dodge ram 1500 long bed 4x4 4.7 li v8 magnum engine, has the started having this problem its got 200,005 miles on it so im gonna put more money to get it fixed its a good truck and I like having no car payments lol
I bought a 02 ram 1500 5.9 and it was running fine and just stalled . So i replaced the ignition coil thinking it was problem now it cranks and wont start and smells flooded ...? When i crank it the rpms gauge moves so that tells me the crank sensors sensing movement now im befuddled as to the cause any help would be a blessing as we were just hit with alot of snow & in dire need of trucks services Thanks Stranded dad
I am haveing the same problem it cranks but won’t start has a check engine light on but no codes will come up did yours do this before you replaced the pcm
Yes, check engine was on. I've done some work on a few like mine and most are the same. I DID also notice these have some issues with the timing chains. If they wear, they can trigger the crank and/or the cam sensors and cause a no start issue.
The truck has long been sold. However, the biggest issue on that Generation truck was the ecm/pcm. They also had a ton of electrical gremlins. Mine was running great when I sold it, but I went through a ton of sensors and had the computer rebuilt before that. Some cases are easier than others. Was a good truck. I upgraded quite a bit now. I bought a 2019 ram, new from the dealer. Love it. But plan to get a older ram to build an off road toy soon. Hope to find a late 90's to early 2000's for my build. My budget has improved, so my options are better. Good luck.
I have the same truck and motor and was running just fine then my wife went in to leave and wouldn't start and now it's a really slow crank. First thing I done was clean up cables and still doing same thing. The only codes was for O2 sensor and two evap system leaks. Trying to figure out what it could be without overspending on other things. I did find out that motor had originally a 5.9 and swapped for 4.7 any ideas on where to start? Appreciate it!
The fuse box and ECM. Mine will run fine but when I turn it off for a moment I go to start it again it won't start. I have to shake fuse box to get it to start
My 2002.5 5.9 v8 died while driving and eventually wouldnt start at all, cranks no start, no codes, full electric power, but gauges stay flat to the needles, mechanic has no clue what to do. Any ideas would be much appreciated
Shawn Vogann Exact same thing is happening to me. Crank no start, no codes, full power, (battery, alternator, starter) checked and are good. I disconnected the battery and when it was reconnected it worked for 2 days. PCM, Ignition Switch? I’m at a loss
I'm in the same boat same engine and year😅 except I drove mine the night before just fine let it sit all day and hopped in that next evening crank no start gauges are flat I don't hear the fuel pump either my wiring looks good from what I can tell and yes it would occasionally die for no reason when driving
For mine, the pcm was the root cause. The other things made it worse. But the pcm is the major suspect. Also check the connecting wires in the harness. A pcm isn't really that expensive for a lifetime rebuilt one, so start with that.
I have a 2002 5.9 liter and I changed the crankshaft sensor and the distributor pick up sensor under the distributor cap . And for good measure cap, rotor and wires. She came to life. All in $180 bucks. Good luck.
Sounds like it could be related to the computer, but not 100% sure on yours. Although your truck and mine have similar electrical and computer systems. I do know that the wiring under the dash in yours has a history of problems. I had a 2000 Ram that I had to have rewired on the OBD plug to the harness. It was doing something similar to what you describe. Once it was rewired, it started right up. Wish I could be more helpful.
I’m having the same problem I have a 2001 Dodge Ram 1500 5.9 liter. I wired a subwoofer then when I tried to start, it started the first time then just died. Now it just cranks but will not start at all. When I give it a little gas it will just barely run then die. Please help
I have an 03 1500 5.7.....cut off while driving now wont start....makes a whining or spinning noise when trying to start ive checked alternator starter and battery it was pretty low on oil any suggestions on what to do next
I'd do a compression test first off. The spinning noise could be a possible broken crank, but would need to hear it. The 5.7 is a good motor and doesn't usually have many issues. After checking compression, and making sure the engine is cranking, verify the basics 1. Are you getting spark, 2. Are you getting fuel, 3. Do you have compression. If you have the basics, even if it runs poorly, it SHOULD run. Fuel, spark, air, and compression is the basics.
All of your problems or not really a problem since it seems that you are guessing at some of them or believing what you read in forums could have been proven with the use of an oscilloscope, I see too many folks replacing parts on a whim without actually testing and it is true, not all problems can be tested with a multimeter but most can be tested with an oscilloscope to include nonelectrical problems such as mechanical problems with the engine as many mechanical problems can be seen in the spark burn line if you know what you are looking at. All you really need to do if you purchase a decent scope is post the waveform online and get a good answer from so many true mechanics. Low budget parts are part of the problem also.
Scopes only work on parts of this vehicle and issue. But feel free to jump into your own scope diag. You'll find your truck still won't start till you go through a few things. Mine had a combination of issues from sitting and having "pros" from Dodge doing their diagnosis with a factory machine. I got the truck almost 2 months after it sat in their back lot. Dodge's end conclusion was a motor replacement. Obviously a flawed final call. Truck runs, and still does today. I no longer own it, but still work on it from time to time.
The problem with diagnosis VIA parts change is if you put in a bad part , you have created another problem . And you may have never fixed the first problem . Someone skilled at using a lab scope can check those chains for slack and SHOW it to you on the screen . You need to get a good scan tool , gather data and identify what is wrong . If you had a broken or corroded connection , wire , etc . , a parts change will never fix it . Beware of no name parts in plain boxes .
I have a 1999 Dodge Ram 1500. My key turns but it doesn't start up and I have no check engine light on! These trucks come in handy and I like not having a car payment!!!!!!
Sure. I started with the PCM, replaced that. I also replaced the battery. At that point the vehicle started but ran really badly. So I replaced the spark plugs, coil packs, and the cam and crank sensors. Then it ran really well. I'm to the point now that I'm going to change out the timing chains, the guides, water pump, etc. And the throttle body sensor. Truck still runs. But I get the "limp mode" issue every now and then. Many of the forums that I see suggest the timing chains or guides. So that's where I am. I'd have it done already, but I have other things going at the same time. I may start this weekend, depending on the weather.

Did you ever get it running??
I did get it running. I had to replace the reluctor wheel. On the crankshaft.
There's a 16 tooth, and a 32 tooth. The camshaft sensor also had to be changed.
@@ashtinx5843 thanks!! I'll look into this tomorrow!!
So you threw every electrical part at it and now it runs?

First disconnect battery and see if the PCM resets.

That's a good question. I want to know also. I have a 1999 Dodge Ram 1500
@@missincredible6087 u can get parts cheap off Ebay especially the coil packs
So what was the specific fix? Was it the PCM. I'm trying to buy a 2004 from a guy on Facebook and that's what his is doing, crank no start

Same 😣
This shit be a factory recall cause the same is happening with this truck everywhere

Also make sure the rotor is spinning if it has a distributor like mine. If it doesn't, your timing chain may be the culprit

Mine died while driving had it towed, I replaced wires plugs and new fuel pump still no start
All you did was guess! Of course if i throw in a new motor with new sensors any car would run smooth!
Really? Try that without a new pcm. I'm sure your rocket will fly. There's always one in the bunch who crys. Now we've found ours.
I truck been parked for like 7 months than replace my transmission and it cranks but won’t start

I have a 2002 dodge ram 1500 truck my crank but won't start
I have 07 just put a transmission in it ran but now just cranks. Have spark and fuel but just cranks
If you have air, spark, fuel and compression any engine should at least fire.
So it turned over before but didn't start?
Sorry for the late reply, my notification didn't work. Yes, it cranked but no start.
