    Have replaced the ECU ( had to use old prom) still will not start, but every once in a while fuel will intermittently spray from injector. have heard that distributor signals the fuel injection off of the position of the cam. Will install new distributor next.

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

No fuel getting Ito spark plugs


If no fuel is getting to the plugs the inyection system is not working. Check for spark in one spark plug. If you don't have spark that is the reason why the injection is not working. When there is no spark, the ECM or injection computer won't work because it needs a signal from the coil, as s proof of spark..

Why do I have to pump the gas pedal to get my 1991 Nissan stanza to start


You probably have a carburetor that feeds fuel to the engine rater than Fuel Injection. Fuel Injection squirts a bit of fuel into the ignition chamber when you turn your key, allowing the car to start, with a carburetor, you have to manually pump the fuel into the ignition chamber to start the engine. Usually Two to Three times should be enough.

Fuel system troubleshooting


I was going to suggest checking for spark but I guess you found it. The computer checks for a reference pulse from the ignition module before allowing the fuel system to start or continue injecting fuel into the cylinders.

Where is my fuel pump at? on a 1995 chevy camero 3.4 yes ran the car out of gas put so in wont start now what should i do first


Your fuel pump is in the tank. Turn on the ignition, and listen if you can hear the pump run in the tank. It will only run a few seconds if the engine is not running. You can repeat this several times to prime the fuel injection.

I trust this is a throttle body fuel injection system?
If it is: purchase a "noid" for your vehicle at an autoparts store this little tester will let you know if your injectors are working. if they are not; they will not be spraying gas into your "bowl" the injectors are little electrical powered solenoids; check fuses, fuseable links and, the efi module.
