If this truck has the 4.3L vortec motor it will not start with 40-45 PSI fuel Pressure.Thius engine requires approx. 56 PSI fuel pressure or it will not start. The fuel pump more than likely needs to be replaced this is a common problem with the 4.3L vortec engine.Change the fuel pump and your problems will be solved.

If its trying to start it could be the fuel pump. Try some start fluid.You should hear the fuel pump cut on when you turn on the ignition for about 2 seconds. If you have fuel check to make sure you have fire. Take a plug wire off and put a screwdriver in it and hold against something metal while turning the engine over. You may need help to do this.If you have fire then its timing. Could be the cashaft position sensor.

I would run the fuel pump for a little while with the fuel line disconnected from the engine into a gas can . Although you might have changed everything you might still have residual water in lines or motor. I would still put dry gas in the tank

I have a cadallic escadale. It will turn over but wont start.


The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

Car wont start


if it backfired then there must be spark , (usually) i would suggest checking if there is fuel pressure (listen to hear the fuel pump when you turn the key to the on position) if you dont hear anything then you may have a fuel pump issue..
