Look for large vacuum leak. if you gotta spray fuel in there to make it run, then the air:fuel ratio is way unbalanced

My 2000 rodeo wont turn over. It starts only with starting fluud. Soon as i stop spraying it stops running. Code has 3 codes about injectors. Does it have anything to do with the computer


Do you have fuel pressure at the fuel rail? If you do not have sufficient fuel pressure you need to check the fuel delivery system. If you do have sufficient fuel pressure at the rail you need to check the cam sensor or distributor pickup, whichever fires the injectors on your model.

1999 pathfinder won't start


The basic story here is you have fuel pressure at the injectors but not going thru the injectors.
So the next question would be, do you have voltage on one side of the injectors and a ground pulse on the other side from the computer ?

96 Lumina 3.1 won't start. It runs when I spray starting fluid in the throttle body. It has 42psi fuel pressure at the fuel rail. Is it bad injectors?


It is not bad injectors, it is lack of injector electrical pulse, never would all the injectors fail at once. See if you have 12 volts (use a 12 volt probing test light, avail at any auto parts store for less than $5) to one wire of the two wire connector of each injector with the ignition key in run position. If the test shows no hot wire at the injector connectors then check fuses marked ECM1 and ECM2 in the under-hood fuse block. If they are popped then you have a shorted harness or component.

Throttle body injectors won't fire No


Check fuel filter and fuel rail. If there is fuel in the rail, and the filter is good, could be low pump pressure or bad signal from computer.

Crank no start: has no spark and only has injector pulse on cyl # 1. if you spray starting fluid directly into throttle body car starts and stays running and has spark and inj. pulse. once you turn the car...


Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.
