This sounds like a bad computer, if your sure the coilpacks are good and you replaced the module and the new module is good and the wiring to the module is good then i would say the wiring to computer or bad computer, this module and coils are hidden in the rear of the motor and go bad often but if say there all good then my next step would be the computer,

Where is the crank position sensor and the ignition module ,coil pack at on a 1998 Pontiac Montana transport


Your spark plug wires go to coils, coils sit on top of ignition module.You have two crank sensors, if crank sensor issue, check the 7x crank sensor, on back side of engine block, down low, two wire connector, wire colors, yellow and purple.

97 oldsmobile achieva wont fire changed coil pack spark plugs cam sensor still wont start


Make sure battery has a full charge and battery connections all good.
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you having a problem with more than one system, I want to check for rpm signal, that usually comes from the crank sensor. Not sure why you replaced cam sensor? I always want to check sensor wiring circuits before replacing anything. Don't replace anything unless your testing points in that direction.

Why wont my 2002 olds alero start when its cold out


One of the coil packs or the ignition module is probably bad. Test for spark when cold. If no spark on any coils suspect the ignition module or crank position sensor. If spark is gone on only one coil check the plugs and wires to that coil pack. If theplugs and wires are ok then replace thge coil pack. Don't forget the obvious load test the battery and clean the battery connections. If the check engine light is on run any diagnostic codes and repair

I HAVE OPEL VECTRA B(ENGINE X16XEL)MODEL 1999 THE ENGINE SHUTDOWN SUDDENLY DURING DRIVING AND NO FAULTS ARE RECORDED IN THE ECU


Check gas and spark. Check if fuel pump is still working. Do you have fuel pressure? Or can you check the fuel pressure? With key on, the pump should have put fuel under pressure in the lines and up to the injectors.
Check ignition system by checking for spark at one of the spark plug wires, with the engine cranking over. You need to see a blue, snapping spark to know the ignition system is good. If no spark on one wire, check another or all of them. If no spark, and no trouble codes-could be a bad crank position sensor. This sensor helps the computer calculate the timing of the spark, the main sensor the computer uses to signal for spark. It signals to the ignition control module (which controls the coils and the primary current to the coils ((the coils-where high voltage is created to cause spark at the plug)) ). So no spark? Could be a bad crank sensor...or a bad ignition control module...
If you have a single coil and not a coil pack, you might want to test that coil, but if shut down while driving, sounds like computer related, so check ignition controls: that would be crank sensor or ignition control module, or in worst case a bad PCM.

Where is the ignition module. Can I get to it from under the hood? Should I replace the Crank module when I replace the ignition module?


Hi.

The ICM is located under the hood, next to the coil pack and spark plug wires. Here the part: Pontiac Grand Am Ignition Control Module (ICM).

If you ar having distribution problem and misfire check also the crankshaft position sensor. It signal is used to control coils and sparks.

Car does not seem to have spark.where is ignition coil car


There's a coil pack that usually sits right on top of the engine. Follow the spark plug wires. Usually the coil pack won't fail completely you might lose 2 cylinders but not all 6. Are you getting a check engine light? It could be the cam or crankshaft sensor, they send signals to the coil pack via the power train control modual.

When i drive it jerks and it wasnt starting for a while one day it wouldnt start after i had been driving for a while i poured water on the coil pack and it started


I first would guess a faulty crankshaft position sensor and then ignition coil/ignition module
The problem is with the spark itself. The spark to plugs and wires are controlled by coil pack, which is attached to ignition coil, which then is connected to crank sensor. You can test crank sensor with an ohmmeter to see if it is good. I would also test each coil pack.

My fiancee's grand am stalled out on her the other night and won't restart. It acts like it but just cuts out as soon as you release the key. I've replaced the fuel pressure reggulator and has a new fuel...


I would test crankshaft position sensor. If coil packs are getting power, then crank sensor should be good. If you are getting spark to all cylinders, then check to make sure you are getting fuel to all cylinders. If you are, then you most likely have a bad fuse or relay that needs to be replaced. Is the fuel pump relay ok? Fuel getting to all cylinders?
