ignition control module???

[sleeper2]

ok so here is my dilema.....
1992 dodge grand caravan SE
3.3 v-6
:laser:

i have no spark and no fire, is this the engine control module or what ?
ya know that little black box on the drivers side fender beside the battery

That is indeed where the ECM is located, BUT
Your problem is most likely a faulty sensor rather than the ECM itself. Need to debug first.

In the modern engine, the spark to each cylinder is controlled bythe computer. All systems use a Crankshaft Position Sensor (CPS). This is used as a timing signal for number one cylinder and used in determining the engine speed (rpms). A second timing signal is generated from either a Hall Effect distributor or a Camshaft Position Sensor (electronic ignitions system - 3.3liter engine uses this system). The computer must see both signals in order to send a signal to the coil (or coil pack module) in order to send spark to the cyclinder.
If no signal in either sensor, no spark occurs.
Typically in this case, the computer sets a catch-all malfunction code of "no timing" when there is a problem in either sensor.

ok so where is this sensor located on this vehicle cause i cant seem to find one in the place where you would think it would be located

Do you find the problem. I have the exact same problem and find the issue.

I have the exact smae problem on a 98 I have replaced the crank sensor still nothing Should I replace the Distributor or the ECM next. Or if possiable is their away to test the Distributor may remove it distrubutor and ohm it out or soemthing.

This system will engange when the key turns on and I will get a moment of 11-12 volts to the coil then the ASD is kicked in and I loss the power to the coil.
