Tech: 1994 Escort won't start, but turns over

My friend is stumped. He has a 94 Escort that came to him with a serp belt that snapped off and broke 1 wire off of the crank sensor plug which has been reattached.

The problem now is when you crank the motor over it will not fire. BUT, he noticed if he would bump the engine with the key and slightly move the key back a little it'll get spark & fire up and run just fine until you shut the motor off.

Do you think this is an ignition switch related problem, or something to do with the belt snapping off and hitting wires?

Thanks Chas

Could be a bad ignition switch. Could be the controller is just allowing a little spark in when it loses power too.

Dunno, what does a voltmeter on the coil do when you try this? What is the resistance across the crank sensor?

What I can tell you is that their is no power to the coil or injectors unless you bump the ignition and move the key back slightly after bumping it'll ignite & run.

I'll have to check the resistance on the crank sensor and get back to you.

These cars have known ignition switch problems...

Update: I talked to my buddy and he's telling me he check for current to the coil, and it has current to the coil when the ignition switch is in the off position. When it's in the on or start position the coil doesn't have power.

Is there power to anything? Is there power at the ECU? If there is no power at the ECU unless the key is held in a weird position, you need to look at the key switch.

I was just told a new ignition switch from Ford was put on. Problem still exists.. Anything else??

I have had this experience with older fords and it was the ignition module. The crank circuit in the module would quit but the run sircuit still worked. As long as when the key was released at the right time they would start. There was no spark in the srank position but there was in run.

Thanks. I'll tell him to give that a try.

Come to find out the ignition module was also replaced. He hopes he didn't get a defective module. Could it be something else?

Thanks Chas

It was put on very incorrectly if the problem described above exists. It's entirely possible the original problem is different and your buddy created a new one by putting the new ignition switch on.

Problem fixed. It appeard that when the serpentine belt broke off and pulled the wires from the crank sensor, it also broke the wires internally in the harness. Once he physically replaced part of the harness, the problem is now fixed.

Thanks for everyones help Chas
