I was going to say crank sensor, but you changed it. What have you done to it latley? Or did this just start? I kinda want to say PCM for some reason. Any welding done on the car latley?

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

Yes you are heading in right right direction. Check to see if there is spark out of coil. Spark at coil means replace distributor or rotor. No spark at coil replace ignition module or crank sensor good luck. Oh yea crank sensor is cheaper i would try that first if there is spark out of coil.

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.

I also have a 2003 2.2L ecotec manual transmission.I have changed plugs,coil,map sincer,still have a misfire problem,i think somthing is wet inside but what that might be i don't know.Any suggestions


I worked on another fuel injected vehicle and found that it had an injector problem which had caused the check engine light to com on telling me that I had a random misfire.I did the same as you did and changed the knock sensor ,the crank position sensor and the cam position sensor only to find out that is was a distributor and injector problem.I would recommend that you test your cam and crank sensor and make sure that they are working properly And if the sensors are good then I would check my fuel system including the injectors to make sure there are no bad ones.

Power at engine module and power to good coil packs but no spark


Sounds like a bad crank sensor or a bad ignition module. If you have a scanner that can read sensor data, you can crank the engine over and see if there is an "RPM" reading. If there is an RPM reading, then the crank sensor is good...Throw the module away. If there is no RPM, replace the crank sensor.

2003 chev malibu wont start due to lack of spark from the coil pack, checked the voltage from the ignition and its ok, changed cam sensor, changed the crank sensor, tested the coil pack and the processor...


That car has 2 crank sensors , did you replace both? One is at the front crank pulley and the other is behind and low on the engine block, above oil pan. Be sure the ICM (ign control module has a good ground, (black wire) it grounds at a bracket where the trans bolts to the engine approx at the 2 o'clock position.
