Common? Well...... it happens. I have had runs of three bad parts in a row, before I got one that actually worked. It was standard practice for me to buy three thermostats for my volkswagen, in order to get one that actually worked......

The pump is just an electric motor. So long as it has good power, and good ground, should work just fine.

 

I think its time for the scrap heap for this dodge

 

Where ya at, and how much? I could use a parts truck........ half or three quarter ton??

 

I am back with truck still messing up, have replaced crank sensor,cam sensor, o2 sensors everything but MAP sensor. Fuel pump and pressure is good. Truck will randomly stall out while driving then sometimes will start up but most times will have to sit, it will crank but not turn over. Sometimes it will drive 10 miles then stall out sometimes not even a mile. I love my truck but I am at a loss as what to do next.It doesnt throw any codes either. I read that bad ignition module could do this to but I am not sure. Can anyone offer any help? I also saw my oil pressure had dropped to zero.Also it isnt like stalling when you run out of gas its like the has been just turned off.Could the crankshaft sensor I put in have been bad, also I read something about a spacer being needed or the new sensor wouldnt function right.

 

Check all your connections at the PCM, sensors, and your grounds on/around the motor.

Ignition module and cam sensor are the same thing.

About all that's left is the PCM itself.

What are you missing when it won't start? Get the fuel pump prime? Got spark?

 

would a bad IAC valve or bad map sensor cause stalling and no start? Also replaced that charcoal canister thing.

 

If it will start if you step on the gas a bit, I would suspect the IAC. If it stalls while you are just runnin' down the road, IAC won't have any control over that.

 

Just a thought....try swapping relays in PDC box.

 

This is a shot in the dark....have you checked the coil?

 

Coil is new but someone told me to recheck the prongs on it , so going to look at that tomorrow.Sure dont want to get a new comp for it, if it is something else.
