Hello everyone: Allow me to introduce myself, My name is Mike. I am a retired Navy jet mechanic. My wife has a 92 250 Dodge van. This quit running while going down the road. We have owned this vehicle for ten years. Compresion and fuel are good. There is no spark at the coil and at the distrributer. I use a Haynes repair manual for diagnostics and repair. The coil, switch plate assembly(camshaft position senser) and crankshaft position senser all test good. I replaced the cap and roter as they were due and showing thier age. The switch plate senser has three leads. One is a pulse wire, it checks good. the other two wires are a power supply wire and a sensor output wire. the Haynes manual does not have wireing diagrames for 92-95 model vans. How do I test these wires and what do I do from here? The PCM reads out good but the ignition switch may be faulty. The ignition switch was replaced in 2010. Who has answers for this? Any help is welcom. Thanks Mike

 

With the key in the ON position, do you have 12 volts across the ignition coil primary?

 

Which wire is the ignition coil primary? I will test it tomorrow.

 

The 2 little wires going to the coil, not the larger spark wire.

I see you're a fellow New Englander. Are you anywhere near the home of basketball?

 

Alloro: I was busy today building a chiminy for my wood stove. The van has to wait. Perhaps tommorow I will have time to test the coil wires. I appreciate your help and interest in this matter. I will contact you again when I know more. Thanks, Mike

 

Power to the coil tested good. Crankshaft sensor tested as open circuit. Book said it should have 0 ohms resistance. How do you read Zero ohms?
I don't know where the home of basketball is, I am in Maine currently, just south of Augusta.

 

Zero ohms is the same as a dead short, just like when touching the meter leads together. Keep in mind that most meter leads when touched together will read about 1.2 ohms due to the resistance in their wires. So you'll want to subtract that figure out of your reading.

 

Thanks for the info. onward to changing the computer. Changed everything else. this is third computer in 10 years for this vehicle. Mike

 

computer is the ONLY major componet I have ever replaced on my 92 B250
