Question about Cars & Trucks
When I turn the ignition to on wait for the fuel pump, 2 times, then turn it to start, the car will start and then die even when I'm pumping the gas pedal trying to keep it running. It seems about every 4 to 5 days of this (approximately 5 minutes daily) it will actually start. I have replaced the Camshaft and Crankshaft Position Sensors and Battery. Sometimes when I do get it running it seems to be running a little rough, other times runs perfect. Has anyone heard of this type of problem.

Running lean , not enough fuel . Have fuel pump pressure an flow tesing done . Have a scan tool hooked up to look at engine sensor data . Any number of thing's can cause this type problem . an looking for a magical fix on here is going to fix it . Newer vehicles have complex electronic's , PCM/ECM engine computer an sensors ! Diagnostic equipment an someone who knows what to look for is what fixes the modern automobile . Training as well !!!! Coolant temp sensor could cause this .

Some GM products also incorporate the oil sender switch into that circuit for fuel pump, so that in case of an accident, engine shuts off, oil pressure drops, in turn, shuts off power to fuel pump. May be worth a look at what your getting for oil pressure, as well as checking switch/sender.

sounds like it may be and ignition relay falling out. i think there is 3 of them under the hood. have to ask is there fuel pressure, spark. i know you changed them but why.
