Rufus N Dufus just bought a 1993 Chevy 3.0 starter 454 been sitting for 2 years motor turns over fine put starter fluid in the carburetor motor started right up but no fuel getting to the carburetor don't know what I'm getting into I need advice
last year i had the very same problem!! ethanol is extremely caustic to rubber. we dont notice it much as we are always putting in new gas, but let the gas sit in the system for 90 days and it starts to eat the rubber hose from the inside. if you don't mind i would like to post a link to what happened to my generator. it started to do that first, close to the tank. the video shows exactly what it does to rubber.i ended up replacing all the rubber gas lines. i no you said it is fuel injected but take a look at it and see. ethanol also will cause a lot of water to collect in the gas tank after sitting for a while. i use heat in mine every other refuel or so. helped a bunch. napa guys were right on with that one.
You are correct about the ethanol! It is nasty stuff, it is a shame the government shoved it down our throats. You are welcome to share the link, I remember watching the video on your channel and it is very informative. Thank you for sharing. When I get to Arizona maybe we can have a few cold ones together! :)
I have a 1989 class C coachman lepruchon motor home, I have a single 40 , The pump works great but the sending unit will not read right, We have tried 3 new ones and none of them read right, It has the F I 460, What can I do to fix it right?
I would check for a clogged catalytic converter; manifold gasket leak; or bad Rotor or rotor cap? Have experienced the symptoms your are describing with these problems.
Hy there . First of all like you videos . i am working on a GM CHEVY 454 RV that was sitting in the yard of my landlord for almost 5 years and i decided that will be a nice project for me . it need allot of working but its a challenging and will be great . Nobody has started the motor in years . some water inside since we are in uk and the wheather is verry wet most of the time . last weeks i started by removing all the spark plugs add ub40 in the cylinder holes for lubrification , i fitted 2 batteries and crank the motor without the spark plug wires in to get oil presure . the engine its sppining good and all working there i think . i have oil presure but i dont know if the fuel pomp is working , i dont know how can i check it . i am not a mechanic by the way . maybe some solution mite help .Regards from Sam and Jenny from UK
Hey! What were your symptoms? Mine acts like it's not getting enough gas, it starts to lose horsepower, and it vibrates like it's about to stall when it acts up. I am wondering if it's the filter or the pump, or maybe even something else! The problem seems to only occur after the engine has ran for a bit, making me think it's an overheated fuel pump, that could be overheating because it's pumping too hard through the filter!
lance Pilon I changed the filter in mine, and, since then my car has run significantly better, with no problems at all. I'd give the filter a shot, because it's cheaper, and if that doesn't help, the pump. But my car feels almost new! And my gas Mileage bumped up by 2-3 mpg.
I'm almost positive your correct fuel can sometimes thicken over time hop everything goes well great video very interesting learned a few things to so thx :)
Vincent Falcone At this point I think the problem may lie within the tank. Looks like I am going to have to drop the fuel tank. Second filter was not clogged at all, not much else left that would cause the probe other than a restricted or faulty fuel pump.
davidgriffin14 Fuel pressure is ok when tested. It may not be when the problem occurs but I can not test it while driving. I think I may still have water in the tank, that would probably cause the same problem. Water would be easier to deal with. I do not want to drop the tank unless it is absolutely necessary. Thank you for your input. I truly appreciate any suggestions.
An engine scope would give you an answer fast. Suggest it to your mechanic, if you can't find the issue. I'm going to carry mine in my RV. OBD does not help with every problem. A scope, on the other hand, rarely misses the issue.
Probably water in the gas tank but COULD be computer related. There is a " pour - in " additive now that harmlessly evaporates water from fuel tanks, Auto Zone will have it. If it's electronic in nature, it's probably a $10 sensor failing under heat load that costs $200 in diagnostic time to find.
I did add some dry gas to the tank, no improvement. I am convinced that the fuel pump is at fault. I the problem persists after a new one is installed I am going to have to look further. Reason I am going with the pump first is that the fuel tank has to come down to repair the fuel filler tube. So while the tank is down I want to eliminate the fuel pump as a possible problem.
Rufus N Dufus Update on my first comment. I MAY have your answer & it's a PAINLESS, relatively cheap fix ! We MAY be barkin' up the wrong tree. The problem you describe is intermittent IGNITION, NOT fuel starvation. It is a VERY common problem here in the sub - tropics where extreme heat and moisture condensation are constant issues with vehicle and marine electronics. ANY parts store can check this for you ( take them the part ) and it's remedied by simply replacing the plug - in IGNITION MODULE, usually about 60 bucks ( non OEM ) . The problem is SO prevalent here that many people who spend time on the road actually carry a spare !
As someone already said you should drain and flush out the tank and then put new gas in. There could be water in the tank for sitting too long. Also use fuel stablizer if it sits for more then 90 days. Another thing you can do is clean the injectors they maybe partially clogged. Hope that helps.
this is the video i was talking about with the ethanol and rubber. messed up the seal on the float in the carb as well. in the end had to replace all the rubber gas lines rebuild the carb again. i was told to drain all the gas i could in the system and use a stabilizer or heat in the tank its self if going to sit more than 90 days. th-cam.com/video/CV_zULGgnb0/w-d-xo.html

To much story and takes forever to get to the point. Gus is over the hill and mow we hear it sat for a while Gas tank is as old as gus so meanwhile why even bother explaining when she's belongs at home l........?
Helpful!! Thanks sir I’m having the same problem and after this video I change my fuel filter and it’s good now !
Thank you so much
I hope everything works out...definately looking forward to more videos!!
sharrin kay Thank you! I am sure there will be many more!

Can you link to the video showing the filter replacing?

Have you seen the vids. about RV's catching fire!
Great video! My father in law having the same problem! Do you know where exactly the fuel pump is on a 2005 mountaineer motor home?
Could you please tell me what was the problem cause I'm having the same problem
manifold leak can cause 02 fault code, cause a lean condition, fuel pumps in these are nfg, an auxiliary fuel pump add can be a fix too

Have you checked the air filter?
Where is the fuel filter located?
Dude I had a similar problem and it was overheated intake air........right on keeping the doggie out of the work area
My problem was a fuel pump issue. Rufus is not allowed to play in the danger zone! :)
did this cause your check engine light to come on ?

Clayton Moore that's happening to me right now on my 05 suburban,you think its fuel filter?

you should do a fuel pressure check.

where i need buy the fuel filter ?
monterrosaminer. try filter place close to building

My money is on the fuel pump! However I do appreciate your suggestion, and if I am wrong I will apply it.
As someone already said you should drain and flush out the tank and then put new gas in. There could be water in the tank for sitting too long. Also use fuel stablizer if it sits for more then 90 days. Another thing you can do is clean the injectors they maybe partially clogged. Hope that helps.

Sorry, I saw Fuel Pump!!!!!!!!!!!!!,,, So Though You had a Carb... Jack, As I Typed 1/2 way Thru,,
Mechanic is trying to cheat me . But if he replaces the fuel filter but the pump is bad
Hi what was the probleme there dis you change the fuel filter and pump
Bad pump maybe
i have the same problem , i think it is fuel filter
To much story and takes forever to get to the point. Gus is over the hill and mow we hear it sat for a while
Gas tank is as old as gus so meanwhile why even bother explaining when she's belongs at home l........?
If you stick to the topic at hand, the video would only be a few minutes long...
Always a clown
Alright already just change it and let us know if it worked. Seriously not interested in your life story.
