Hi,

Initially, the ECU/ECM (engine control management) is to be suspected. Chances are the servo/drive transistor that switches the fuel injector on/off is shorted and therefore there is constant power supplied. Am not sure if service shops in your area would do component level repair, but it is possible just to replace the discreet component(s) that may be defective. Often, to my understanding, repairs involve replacement of the entire unit/assembly.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Changed the fuel pump and filter...still won't start


Check the injector circuit. There should be a fuse for the injectors. Each injector has a power wire and a ground wire. The power wire should show current when key is on.
Your fuel pressure should show around 50 psi with key on. Is it?
How to check the injector ground circuit: Use a test light. Clip the lead of the test light to the positive battery post, and use the probe into the ground terminal of an injector connector (the connector is unplugged). Now observe the test light while someone cranks the car. If injector ground circuit is working right, the test light will be blinking-meaning the computer is correctly grounding the injector circuit for a split-second each time the light blinks. If no light, check ground wire from injector to computer. If light does not blink but is steady, computer failure.

Dead cylinder number 2 bad injector number 2


use a digital volt meter,put it on the ohm scale check number 2 fuel injector should be 11 to 16 ohms if not reads zero fuel injector faulty.if numbe 2 fuel injector okay.use noid light hook it to fuel injector electrical connector with fuel injector disconnected and see if pcm is firing the fuel injector noid light should blink when cranking the engine.if light steady pcm not firing 2 fuel injector,if noid light dont light up.there is a open in the wiring connector 2 fuel injector 2. if fuel injector okay,check spark plug, carbon foul you have a bad ignition coil or wire if you see oil on spark plug you have worn piston ring or leaking valve guides allowing oil to foul out spark plug.do a compression test check compression to see condition of the cylinder.

Car cut off like it ran out of gas, there is plenty of gas


check fuel pump is working, go to the engine compartment and take the fuel line off the injector rail and place it in a bottle then have a friend to turn the engine over and see if you have a steady flow of petrol flowing into the bottle, if you dont have any fuel at all id say its your pump. if you have a start stop flow or a week flow try changing your fuel filter

My 1998 Pontiac Grand Prix GT quit running after I flushed the cooling system.I put in new plugs, new module, and new coils. It drowns plugs and doesn't seem to be getting a hot spark. It starts when...


It sounds like the computer is operating the system in full rich mode. If all the plugs are fuel fouled then, it's something that effects all cylinders equally. If so, then check the ECT (engine coolant temperature) sensor. Make sure it is connected and in good condition. If the sensor lead is disconnected causing an open circuit, the computer will attempt to run the engine like it's at -274deg. kelvin. Also check the MAP sensor hose for cracks and damage. If you are checking the same plug each time then you may have a shorted injector or driver. Attach a noid light or a high impedance test light to the injector harness. If the light stays on with out blinking while the engine is running then the injector driver is shorted out and PCM replacement will be required. If that's OK then check the injector for a short using an ohm meter.

Theft system


You have to take the key out for five -10 seconds after you wait ten mins in the on position. The reset does not take effect until you remove the key.

1998 pontiac grand am misfire cyl 4


I'm a bit confused concerning your spark plug wires as the standard 2.2 engine does not have them, so my suggestion is based on the 2.2 engine as the 4 cylinder you state you have.
If the secondary electrical has been replaced, I would suggest inspecting the fuel injectors for operation.
The easiest way to test the operation of the fuel injectors is to listen for a clicking sound coming from the injectors while the engine is running. This is accomplished using a mechanic's stethoscope, or a long screwdriver. Place the end of the stethoscope or the screwdriver (tip end, not handle) onto the body of the injector. Place the ear pieces of the stethoscope in your ears, or if using a screwdriver, place your ear on top of the handle. An audible clicking noise should be heard; this is the solenoid operating. If the injector makes this noise, the injector driver circuit and computer are operating as designed. Continue testing all the injectors this way.
If all appear to be functioning we can move on to the next suggestion.
Let me know.
Regards.
