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.
