Default 2001 dodge ram starting problems

Here we go, I have a 2001 ram 1500 4x4 5.2l the truck has 53k i changed plugs wires cap and rotor over the last summer lately i have been having a strange problem that i am looking for advice on. When the truck is cold it starts fine if i drive for 10-15 minutes and shut it off it starts right up fine, if I let the truck sit for like a half hour it cranks and cranks before she fires up and it seems like the computer is dumping more fuel to compensate. I tried to buy good tune up parts MSD wires, champion truck plugs, napa brass cap. My thinking is that when the truck sits after been warm the cap is condensating?

Any help or ideas would be cool

Any fuel leaks? Sounds like perhaps the fuel is draining out of the lines if it sits for a while after running. I'd pass on the champion truck plugs next time. In the dozens of times I've changed spark plugs on various vehicles I've only ever broken the truck plugs, and between my friend and myself we broke 3 in one change.

Can't notice any fuel leaks, what makes me think it is electrical is that when it does start there is a strong fuel smell like the computer is richening up the mix because it doesn't want to start?

Thanks for the tip on the truck plugs[&o]

o2 sensors going bad? your computer may not report bad o2's (it's a bug the dealer can fix, but I like mine the way it is)
Air filter good? Another thought is maybe your IAC is dirty... take the throttle body off and clean it thoroghly and pull the IAC and clean it as well.

Had kinda the same problem on my 99. Try this next time, barely press on the gas, if it starts let off the throttle.If it dies restart the same way but dont let off the throttle you can make it home as long as you dont idle. The problem was a "air motor" sensor on the intake. $65 part at the dealership.

Thanks Green, The thing that is weird about this is the truck runs fines and idles fine once i get it started the problem only occurs if the truck is warm and i let it sit for 10-15 minutes and try to start it, it just cranks until i put my foot into it and then it starts almost like it is flooded or or not getting good spark pulled a couple plugs the other day and they look like a possible lean condition.

Think i fixed the problem finally pulled the cap and it was toast not even one year on it I think I am going to have to route the wires according to the dodge recommendation. I think that is why it condensated all the contacts in the cap black as soot with white powder everwhere. Just Glad to have it fixed.

Default RE: 2001 dodge ram starting problems

all right, I thought i had this fixed but it is still starting like crap, I have done a fuel pressure test and the system holds pressure for about 10-15 minutes and then bleeds down to nothing, and with the gas smell when it starts i was thinking it was an injector leaking so i tested them with the truck running by pulling the connector of each one and listening for changes in the motor but really didn't notice any serious changes, so then we checked the resistance and they all seemed within range of the haynes manual spec.

My questions are should the fuel system hold pressure longer than the 10-15, the only way to get the truck to start is to put the throttle to the floor if it was a sensor which would be the most logical place to start iat, map, tps, engine temp? or is there a way to pressure test the injectors to see which one might be bleeding down. Or a way to test the pump to fuel rail section of the fuel system the fuel pressure guage i have just threads on to the schrader valve on the fuel rail.

I am so puzzled by this because the truck runs and idles fine once it starts.

Any help please

It is possible for the fuel system to hold pressure indefinatly....If all of the components are functioning properly....
BTW... what did your fuel pressure read??

Fuel pressure was approximately 48psi and bled done below 20 psi within a half hour my thinking is fuel injector leaking into plenum[:@]

you probably do have leaky fuel injectors, get some BG 44k fuel injector cleaner, run your tank down close to empty and pour it in, then fill up with about 5~8 gal of fuel, then drive until it's almost gone before adding any. this will give it a good concentate of the cleaner and hopefully speed up the cleaning.

Well its finally fixedq, After talking with a mechanic friend he said to check the injectors pulled all of them left them connected to fuel rail, pressurized the system watched for ten minutes or so and sure enought the number 4 injector started to leak swapped it out and she runs and starts like a champ. Yeah!!!!! hopefully nothing else for a bit.

when the fuel lines heat up they expand and are sucking air as they cool they contract try replacing fuel lines

good to hear its fixed. i had a problem i was chasing with an engine POP under load, you could even hear a slight pop at idle, i started unplugging injectors one by one with it running till i found the one that made the idle smooth again, drove it on 7 injectors and not one pop. i pulled them all and hooked a couple wire leads to them from the battery so i could get them to open and close when i touched it, and did this at the same time i was holding the injector down on top of a can of cleaner without the nozzle on it so when i pressed the injector down it would try and shoot the cleaner into it and then it would open when i touched the contacts with the wires from the battery. i cleaned them all and found one injector (the one that was being suspected) wasn't closing all the way when i took the lead off. so i cleaned the crap out of it and it started working as it should had, be fine ever since. its the little things that cause the big problems sometimes.

I had a similar problem. Sometimes my 2001 RAM 1500 would stall just driving around and not start again. Believe it or not, it turned out to be the coolant temperature sensor!

If the sensor or wiring is intermittent or defective, the computer reads it as -40 degrees F. When this happens, it chokes off the air and dumps fuel to get the engine lit. Of course, it was not -40 degrees F but if the computer sees this low temperature when driving (like an intermittent connector) the motor will just die where it is.

I chased my tail for weeks. put in a new CAM sensor, crank sensor and even disconnected the manifolds from the CAT thinking it was plugged. My coolant temp sensor connector was bad, so I swapped it out and the truck runs so smooth you can barely tell it is running at idle. Who woulda thunk a coolant temp sensor would leave someone stranded but that's what happened.
