Check to see that fuel pump is working. The pump is located in the fuel tank. If you turn the key to the on position you should hear it running. Check the fuel pump relay for correct operation also.

1990 chevy blazer 350 ci throttle body fuel injected . the motor is flooding out u can see the injectors keep dumping fuel into the throttle body


Sounds like you have an injector leaking. Have someone just cycle the key on and off to run the fuel pump but don't crank the engine. If you see fuel dripping from the injectors, unbolt the injector cover on the throttle body, remove the injectors and replace the orings around the injectors.

1990 f 350 7.3 liter runs fine until fuel tank


install clear plastin line in the return from the injector pump, any air in the fuel means trouble, somewhere in the fuel system its drawing air , usually neat the tanks, but not leaking enough for fuel to leak

Had no spark. Replaced ignition mod, 2 coil packs, and computer. I now have fire; problem is engine will not run, the fuel injector sprays fuel (too much i think). When i unplug the injector the engine...


Check for any wiring pinch which might have occurred when the injector was replaced. The injector is driven directly by the computer, so it seems to point at the new computer as being faulty. (pulse signal is always 'on')

I have fire and fule I just replaced the spark plugs and redid the timeing and it still wont start what ellse can I do?


are the injectors opening? fuel pressure doesn't mean the injectors are delivering any fuel to the cylinders, does the system have any trouble codes? if u are not sure if the injectors are getting a signal buy a NOID tester from NAPA or a tool dealer like Snap-On, it is very easy to use, plug it onto the fuel injector connector and crank the engine, if the injectors are getting a signal the light will flash, it is kinda hard to see so do it in the evening, if the injectors are not working then check to see if the computer has power, if the computer checks ok then u may have an issue with the engine wiring harness, very common on this car. also make sure the timing belt is ok.

Replaced cyl head assy, now engine won't start


Fuel pump won't run unless it starts, it is designed to run for two seconds then shut off, if it were to run and you had a damaged line you would cause a fire. The cam shaft sensor gives you spark and injector firing but the crank sensor has to work two, check to see if you pinched off the wires on the crank sensor, also does it have a coil pack? If it does leave me a post.

I have a 1990 Firebird 3.1 Crossfire fuel injection. The problem that I am having is that i am getting no injector singal to the injectors. I have checked fuses, checked fuel pressure, and fire on spark...


I believe this is a dis system.
it sounds like you have a bad crankshaft position sensor, the crank sensor is used by the pcm for fuel injector timing.

on this motor it is mounted behind the harmonic balancer, be carefull when removing the balancer because there thin metal plates indexed into the back of it, these plates are what initiate the crank shaft signal to the pcm.

good luck

No injector pulse, no current to the injector


Check the pickup in the distributor as this is the cam sensor. The injectors run of the pulses created while the rotor is turning around. It should be a plastic disk located under the rotor button.
