Question about 1994 Pontiac Grand Am

1 Answer

Engine cranks but doesn't start

The 94 Grand Am that won't start is getting gas however, I can't put an in line spark tester because there aren't any spark plug wires. How can I determine if there is spark with an engine that uses the ICI (ignition control module)?

Pull off the hat and lay it up on the wipers. Run plug wires from the coil adapter towers to the plugs. Run a ground wire to ground the hat. Check for spark with a spark tester one wire at a time. Don't get near it when you have a friend crank it, there is enough voltage in the ignition system of a 2.3 quad 4 to kill you. I'm not kidding, just be careful.

What can cause a 1995 corcica to go dead and smell of gas


Check for leaking fuel lines or a puddle of gas under the car. If the exhaust smells like gas then the gas isn't burning completely and may be a number of things like spark plugs, plug wires, clogged air intake, fuel injector that stuck open...

94 grand cherokee cutsoff going down the road then won't start until it sets for a while


When it won't start someone will need to find out if you are dealing with a no-spark or no-fuel problem to proceed.
If the check engine light is on you should get the computer scanned for trouble codes.

The starter cranks normally but the engine won't start


Hi there:
You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

New alternator and battery installed still will not start


Not much to go on. Try replacing the start relay with another one in the fuse box. Thats if it won't crank. If it cranks need to see if you are getting fuel look down the TB carburetor looking thing on top of engine with key on and someone cranking engine. Put one of those testers in line with the spark plug wire it has a light inside that flashes when the engine fires. Or you could disconnect sparkplug end and hold on but it will knock you on your *** and could KILL you so don't do it

My 2000 Dodge Grand Caravan will crank but won't start.


Hi, if an engine cranks but refuses to start, it lacks ignition, fuel or compression. When the engine cranks normally but won't start, you need to check ignition, fuel and compression. Ignition is easy enough to check with a spark tester or by positioning a plug wire near a good ground. No spark? The most likely causes would be a failed ignition module, distributor pickup or crankshaft position (CKP) sensor.

The 94 grand am doesn't start


One suggestion I can make to see if your car is getting spark is by purchasing an in-line spark tester from an auto parts store (not very expensive) and pulling each spark plug wire off and checking with the tester.

If you are getting spark to every wire and they all seem to be the same brightness, try replacing your spark plugs with the recommended plugs and setting the gap with a spark plug gapper.

To see if you are getting fuel to each cylinder, try to start the car a few times with the fuel pedal to the floor (for fuel injected engines) to clear a flooded engine and then pull the spark plugs out of the engine and smell them to see if you can smell fuel, if there isn't a strong scent of fuel, you may not be getting fuel and you'd probably need to take your car to a mechanic to have them check the fuel system and injectors.

I hope I could help you get started to narrow down the problem. Good luck and don't forget to rate! Thank you.
