Hey everyone i could really use some help ive been trying to fix my sisters car and im stumped. we bought the car with a 3.4l in it from a chevy venture, it had overheating problems and suspected head gasket failure w/ no oil coolant mix. I have replace the following; head gaskets, head bolts, heads were resurfaced and a shim was added with head gaskets, upper and lower intake gaskets, throttle body gaskets, injector o-rings, spark plugs, plug wires, oil change and filter, thermostat, cooling system flush, power steering pump, air filter, fuel filter, and fuel pump along with some other things like tires and rotors and brakes but those wouldnt cause the problems. after all that work was done and the car was reassembled it will just crank all day but wont start, there is no fuel pressure but there is spark and proper compression. the relay under the hood clicks but neither the old pump or the new one makes any noise and the there is no power at the connection. i was looking around and came across all of the complaints about the passcode theft system and it deactivating the pump and injectors. my theft light is on and it stays on and does not blink. i have tried the ten minute reset thing and i tried the resistor bypass thing, and the car still only cranks and will not start. anybody have any help at all they can offer ill answer any other questions you might have. thank you for any help,

hi, I have a chevrolet malibu classic 2004,and i did the bypass thing to it and it didnt work,the car start in the cold morning but after driving the car for around 20 min it wont start,i place the key in on position and the check engine light is on and i can hear the fuel pump working and the car can start,but if i place the key in on position and the check engine light dont come on then the fuel pump doesnt work and the car wont start,i replace the fuel pump relay and still having the problem,i took out the relay and i place a tester in one of the slots and then i putted the key to on position and the tester light was weak and the check engine light off and when the check engine light is on the tester light is stronger,looks like the relay is receiving low volts from somewhere

Maybe ignition switch, the electrical one not key. Should be mounted on back of key switch assy.

I am having the exact same problem, my mechanic or dealer can't find out what the problem is. Seems like outside temp is effecting what is happening. Same exact problem with check engine light, hearing fuel pump, etc. Where you able t find what the problem was, cost, any info will help. Thank you!!!!

Were you planning on taking the vehicle to the dealership to be looked at? Please keep me posted when the issue has been taken care of.

Thanks for you reply! I already took it to the dealership and they had no clue after diagnostics. They just wanted to change the fuel pump to see if thats what it was, $700 for the pump alone! Also my reg mechanic of 11years diagnosed it as well. outside hot temp seems to have a definate effect. What do you suggest? Thank you!

Caron, just got to my car after the heat of the day and the check engine light came on when I turned the key to on, heard the fuel pump come on and she cranked up right away! The problem started back in April when the temps started to get hot here in Pensacola, FL. Also when the check engine light does not come on, the fuel pump relay makes buzzing sound, changed that out.
