SOURCE: car wont start

I noticed you replace the crankshaft sensor, but not the CAMshaft sensor.
The Ignition module takes the input of both sensors to tell the coil when to energize.
This sensor should come up as an error code when you attach a obd reader.
Even if your light is not on - there may be a code. If it is not your vehicle originally, some people pull the bulb!

spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]

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.

I have a 1996 mercury sable that wont srat i pulled up at home about 2 hours later tried o leave and it did not start, i checked the coil pack for a spark and it gave no fire, so i replaced the coil pack...


Probably the crank sensor, do you hear the fuel pump 'buzz' when you turn on the key (not cranking the engine, just key on)? If you do hear the fuel pump (only lasts about 2 seconds), it may be the ignition module, otherwise it is probably the crank sensor.

How to fix a coail pack on a 1987 Pontiac 6000?


Coil packs are replaced not repaired if found to be defective. ---prev.gif next.gif DISTRIBUTORLESS IGNITION SYSTEMS Starting in 1987, some models came with engines equipped with a Computer Controlled Coil Ignition (C3I) or Distributorless Ignition System (DIS). Fig. 1: Triggering system used on the C3I fast start system 86812034.gif
Fig. 2: Electrical schematic on C3I ignition system 86812031.gif Both DIS and C3I system consists of the coil pack, ignition module, crankshaft sensor, interrupter rings and ignition control module (ICM). All components are serviced as complete assemblies, although individual coils are available for Type 2 coil packs. Since the ICM controls the ignition timing, no timing adjustments are necessary or possible.

I already replaced the crankshaft sensor. When the car gets hot it won't crank and then when it cools down it will start back up 2000 Grand Prix 3.8


Could be ignition control module or fuel pump, if you don't have spark to spark plug's, control module, also check for fuel pressure at fuel pump pressure port, port will be on fuel rail.
