Have you checked to see if the coil is getting battery voltage with the key on ? Problem could be the EEC relay.
Do you know for a fact the rotor in the distributor is turning when the engine is cranking ?

SOURCE: I have a 93 mercury topaz 4cyl 2.3L that stalls

It sounds to me like you replaced everything but the most likely cause of a stall while driving...The crank sensor.

SOURCE: no gas, no spark, 1991 chevy cavalier 2.2l 4cyl

This is an all too common problem with the Cavalier and other GM J-body cars. Usually it is because of the crankshaft position sensor or the harness going between it and the DIS (aka ignition module). Without the DIS seeing a signal from the crank sensor, it doesn't know when to trigger fuel and spark.

Sometimes this can also be caused by a faulty ignition switch. The switch will allow you to "crank" the car, but it doesn't make the proper connections for the ignition system, so the car never actually runs.

The previously indicated oil pressure switch could also be causing the problem, but if you hear your fuel pump run then it's OK.

Hopefully this helps. If not, your Cavalier is as messed up as mine and probably not worth fixing.

1999 nissan maxima dont start but crake


The first step is to determine if it's a spark, fuel, or compression problem. Here's a quick way to find out which of the three is missing. Remove a plug wire, insert a Phillips screwdriver or spare plug piece of bare wire into the plug wire boot and place the end near the engine block (do not hold the plug wire while cranking the engine unless you want a shocking experience). If there's a spark when the engine is cranked, it has ignition. The problem is either fuel or compression. If the engine has an overhead cam with a timing belt, loosen the cover over the timing belt and check the belt. If the belt is okay, the problem is no fuel. Listen for the electric fuel pump in the fuel tank to make a buzzing noise when the ignition is turned on (you may have to open the gas cap to hear it). You won't hear anything if the pump has died. Diagnostics can now be focused on the fuel pump circuit to determine if the pump, relay or wiring is causing the no start. If the relay has voltage but the pump isn't running, you'll probably have to drop the fuel tank to check the wiring connector at the pump. If the problem is no spark, anything in the ignition circuit that creates the spark may be at fault. Use your AutoTap Express DIY to look for an RPM signal from the Crankshaft Position sensor while cranking the engine. A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. If you have an RPM signal, a bad ignition module or PCM may not be switching the coil(s) on and off. Using a voltmeter, check for voltage at the coils with the key on and while cranking the engine. The voltage should be switching on and off. In ignition systems with a single coil and distributor, a bad coil or a cracked distributor cap or rotor can prevent the spark plugs from firing. On multi-coil, distributorless ignition systems and coil-on-plug systems; one coil failure may cause an engine to misfire, but it won't prevent it from starting. What's causing the no-start? All engines require three things to start and run: spark, fuel and compression. If any one of these isn't there, you aren't going anywhere

Engine died while driving, no spark, replaced coil, now starts, idles, runs well at low rpm, but misfires when accelerating. No check engine costs thrown. What should I check next.


Change your ignition module. The distributor is a weak point of the Honda, I will always change out the whole thing than just try the coil.

Cherokee revs up wont start


Your description is too vague to give specific advise. However, if you are stating that the engine turns over when you turn the key but it wont run, then you want to check a few possibilities. Fuel, Spark, compression. Make sure the engine is getting fuel. Then check for spark at one of the plug wires. Then check cylinder compression. No fuel can be a fuel pump, plugged filter, or pump electrical connection, like pump relay or wires. Spark problem can be ignition coil, coil pack, distributor module, distributor points. Compression can be piston rings, valves, head gasket. This is not everything, but it may help you!

1988 Jeep Wrangler starting problems. I replaced the ignition module, spark plug wires, coil, distributor module, and my jeep will not start. It gets fuel, turns over, but still not starting. It is a 1988...


you are saying it is getting spark, and fuel, right? If it is getting spark, and fuel in to the throttle body, check compression-make sure the Mass Air Flow sensor is plugged in, and double check your spark-you say you replaced all those ignition items, but do not say that you have spark.
