Ignition problem with Explorer 92

[Auto2510]

the car doesn't start anymore. The battery is fine; the starter is working nevertheless the car doesn't start. I took a spark plug out and looked for the spark. There was no spark. The question now is: what do I have to look for to find the solution to the problem.

Is the starter turning the motor over. Is it just not firing?

Check the crank sensor and wiring. Sometimes merely disconnecting it and reconnecting it will work. Some have reported success by tapping on it with the handle of a screwdriver.


Check for ignition signal to coil pack.

Report back your findings.

The starter is doing well; the ignition system doesn't send the signal to the spark plugs. The spark isn't present. Where do I find the crank sensor?

About 10 oclock on the crank pulley mounted to the timing cover

One of the first things I would probably do is attempt to pull codes from the computer. Some ignition issues can leave codes in the computer's memory.

Does the fuel pump run? Does the CEL come on with the key turned on? If the engine managment system loses power or ground, you will lose both spark and fuel -- causing a no start.

I'd agree strongly with MrShorty for two reasons: The computer may give you a good idea what the problem is; and the computer may be the problem.

First, thanks to all of you who responded to the thread.
In the meanwhile I talked to some people and a guy from NAPA asked me about the function of the ICM. According to his experience this part is quite often the problem in a situation like I experience. Therefore, I took out the coil pack and the ICM. Fortunately, the ICM was OK, otherwise I would have had to invest some money. However, it turned out the coil pack was bad. I ordered a new coil pack. It should arrive end of this week. I will see whether the replacement will really solve the problem.
