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.

Why won't 96 grand am start ate being wrecked?


You will have to determine if the vehicle has spark as well as fuel pressure. Pull a plug wire off and ground it over the engine. Crank the engine and it should spark. If spark is ok, you will most likely have a fuel supply issue. You will need to hook a fuel pressure gauge to the fuel rail test port to determine if pressure is available. If no pressure suspect a fuel pump or power/ground supply issue to it

Car want fire up


what engine ? what displacement?
USA? car?
it cranks robustly but will not start the engine.
the classic 100year test on gas engines is:
1: lost compression.
2:lost spark
3: lost fueling or flooded.
in that order. most folks skip #1 ,due to hope deal and no guage.

and then check spark got spark to all 6 or 8 spark plugs>
yes, good. some 94 have a distributor, is it loose>?
no, fix spark.
3: are spark plug tips dry, try test fuel , spray fuel.
3a: are spark pug tips soaking wet in fuel;?
yes, its flooded, (wideopen throttle, cranking) unfloods it.
keep in mind, flooding can happen on 1 cylinder only. MPI
or all.

I have a 1994 Grand AM, 3100 engine, I was driving down the road when it starting to shut off. now it doesn't start. I checked the spark, it's ok. I have 40# ish on gas and if I spray starting...


IT ONLY TAKES GAS,SPARK AND COMPRESSION TO START. EVEN THOUGH U ARE GETTING GAS UP TO THE RAIL U NEED TO GET SOME NOID LIGHTS. YOUR LOCAL PART STORE CAN RENT THEM TO U. SOUNDS TO ME LIKE THE INJECTORS MAY NOT BE PULSING. SO U MAY HAVE A BROKEN WIRE,IGNITION MODULE PROBLEM OR ECM ISSUE.

I have a 2000 grand voyager and the motor turns over but will not start. What could be wrong with it?


its either not getting gas or its not getting spark to the spark plugs.. check to see if its a gas problem by spraying wd40 directly into the air intake as you try to start it up...if the motor tries to start up then youre having a problem getting gas. This could be a fuel pump, clogged fuel filter, injection pump, or even a computer problem. To check if it is getting spark, pull out one spark plug, leave the wire on and touch a screwdriver to the side of the spark plug and the same time to the engine to ground it.. while grounding it on the engine, have someone bump the key to start it...if you see spark in the gap of the plug then you are getting spark and there is no problem there... if not, it could be possibly be a distributer or electronic ignition problem

93 Jeep Grand Cherokee Won't start


The crankshaft position sensor was seriously problematic in those old jeeps. It's located towards the top of the bell housing slightly to the driver's side I think.

How do I change the rear 3 spark plugs on a '94 Grand Caravan?


Yes, these are tough to get at from the top. Put the front on jack stands or ramps, and you can reach them a little easier from the bottom. You just need to reach up where the exhaust pipe comes down, and you can even see what you're doing this way.

Engine cranks but doesn't start


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.

Check ur spark plugs for wetness, if u have water in ur cylinders, you have a gasket problem. 94-95 grand am had a problem with intake gaskets, but my grand am also had a manufacture error on the head gasket too. The dragged the heads over it putting the heads back on and smashed the rings..
