No, the injectors are not all going to go bad at once.
They can easily be checked by providing the proper voltage across their terminals. (But some are 6 volts with resistor packs, so be careful.) More like is the main fuel injection brain box. But it could be something simple, like the wire from the distributer to the brain box being off. You need to find a full fuel injection trouble shooting book.

What will cause a 1990 geo storm sohc to run rough or not start? Changed, plugs, wires,cap, rotor?


Except for the ignition coil, that about takes care of the secondary ignition system. You should check to see if you have a good strong blue spark at one of the spark plug wires. If no spark, check the coil and the crank position sensor for one place to start, also the ignition control module. If you do have spark, the ignition should be good, and then you could concentrate elsewhere.
If there is a schrader valve on top of the engine-a fuel pressure test port-it would be easy to check fuel pressure. Autozone and others loan a fuel pressure tester. Possibly, a 1990 Storm may require a temporary "tee fitting" in the fuel line somewhere to test pressure. Look for the test port- it may have a cap that unscrews. It would be located in the fuel rail or the line to the injectors.

Beyond that, other problems could be dirty injectors, a malfunctioning EGR valve, a large intake manifold gasket leak, or worst case, a mechanical internal problem. If it gets to that, perform a compression test. If you have good compression in all cylinders, it should be good internally.

1993 mazda mx3 won't start


If the fuel filter was very dirty the injectors may be clogged up . How much pressure do you have to the fuel rail ? How did you check spark ? How good is the compression ?

2004 ford explorer will not start but turns over


For a no start , cranks over ok. be sure you have fuel pressure at the fuel rail first, before checking the injectors. There should be more that 40 psi at the rail... if not .. you might have a fuel pump problem. Even if you have fuel pressure at the fuel rail... the next thing I would check for,,, is spark !! Make sure you have spark at the spark plugs. The order would be... fuel pressure first and then spark , , then injector pulse. !! Then plugged exhaust.... then bad fuel then engine timing. The injectors have power to them all the time. The PCM controls the ground to the injectors. So you would have to monitor the ground side of the injectors. So checking injectors is kinda complicated. Hope this helps you. Good luck.

My 2001 Saturn, will start but not stay running. We have checked the fuel pump and all fluids. Did a compression check this morning, fuel injectors are not injecting fuel into fuel rail. Why is engine...


You said, 'fuel injectors are not injecting fuel into fuel rail' but it's my understanding that the fuel rail gasoline is supplied by the pump, and the fuel injectors just pulse to allow fuel to get to the cylinders. I would check out the fuel delivery problem further. Check for pressure in the fuel rail that is within specs.

If not, then the pump or fuel pressure regulator may be the problem. Check the fuse for the fuel pump. If good, then the pump may be bad in the tank.

Good luck on this.

1997 Chevy Silverado 1500 4x4 will not start. Getting spark checked all fuses, changed rotar - spark plug wires,


Have you checked the fuel pressure? Fuel pumps are a common failure item on those trucks. Pick up a cheap fuel pressure gauge and hook it up to the shrader valve on the fuel rail. With the ignition on and you should have 55-65psi. Even if it's a few psi below spec it could stop the engine from firing.Once you determine the fuel pressure isn't adequate make sure you have a good power and ground at the fuel pump. If that checks out, time for a new fuel pump module. I recommend only replacing it with an AC delco unit, I've heard bad stories about aftermarket replacements.
You could also spray some carb cleaner or starting fluid in the throttle body and crank the engine over. If it runs for a few seconds after spraying starting fluid in you know you have a fuel delivery problem.

95 Camaro Z-28 starts hard


Need to verify fuel pressure at the injector rail with the engine cranking and with the key on and engine off. Specification is 55 - 61psi. The pressure should build with one cycle of the key. If the pressure is slow to build up there may be a restriction in the system between the pump and fuel rail .
The system should hold pressure without leaking down. If it leaks down there is a problem. If all is good there Checking for a good blue spark at several plugs to verify the ignition system is working ok. A vacuum leak could also cause a hard start issue.
A bad pick up coil or weak crank sensor can cause hard start issues also.

Engine turns over but wont fire up


Check to ensure that there is fuel to the injectors using a pressure gauge on the schrader valve on the injector rail or fuel filter (which ever has it).

Check engine compression with a proper compression tester.

Buy an inline spark checking tool and install it between each spark plug and wire to ensure that you're getting spark to each cylinder while cranking.

These three things cover the basics. Once you've tested all these things, you can further diagnose the problem.

On 1999 4.0 Explorer, engine turns over but does not start.


An engine needs three things to run : Fuel, Compression and Fire. Check to make sure you are getting fire to the spark plugs. The fuel pressure regulator on the injector rail may be bad. There is a schrader valve on the injector rail, check to see if there is fuel there. It is a valve like a tire valve, depress it slightly to see if there is fuel there.
