I have a 93 Dodge Stealth, base model, 5spd, 159K miles.
Its had some problems for awhile about not wanting to start after a rain, but after turning it over a couple times it would start. However now it wont start following a rain. After the weather clears up and dries out a bit, it starts just fine. And at all other times it runs fine.
The engine turns over fine, and the sparks fire good too. I have cracked a fuel line and it is getting fuel just fine. However, I havent checked to see if the injectors are working right after a rain, mainly because Im not sure how to.
Any ideas or suggestions?

i agree about the short, though i have no idea where to start looking.
ive heard that the wires to the crankshaft sensor can become worn after a few years. if those wires are shorting out could it cause my car not to run?

If the CAS is disconnected or malfunctioning, it will not send the signal to the ECU which in turn will not allow the PTU to fire to coils or the fuel pump to run. Next time this happens, see if you are getting spark and fuel at that time, then you will know for sure if it is the CAS.

Well just got new plugs and new plug wires. No change, still wont crank.
However I did check for spark and I am getting a good strong spark.
As for checking the fuel situation....well I have opened a fuel line up and turned the car over, this results in plenty of gas. Not certain if injectors are working or not...however the exhaust pipe smells like gas after I turn it over.
Theoretically this would mean that I have gas and spark.
Any ideas as to what to check on next?

Is it still only occurring after a rain? Does it do it after every rain? Sorry about the ??, but it is hard to armchair troubleshoot.
If water is getting on your CAS, it will ground it out and possibly cause the symptoms you describe, once it dries out it would be back to normal.

That could happen (t-belt rubbing the wires), seems unlikely, but you never know. The CAS is on top of the crank, behind the pulley, near the timing marks. It is kind of hard to see with out removing the t belt cover(s). I'll check in the manual and see what it says tomorrow, if I get the chance.

Ohhh, SOHC, that does change things abit. I have never worked on a SOHC motor before so I only have rudimentary knowledge of it. Does it have a distributor cap on it. If it does, replace it as it could have a crack in it. You man not be able to see it with the naked eye either. If it is a fairly new cap, run a very (very) thin layer of silicon lubricant around the edge of the cap and install it.
Does it have the "rotor bug" in the cap, if so replace it also.
Let me know. Manual at 3sx performance
It cost 89$, but believe me, it is worth every penny and then some. It is an official Stealership service manual that has everything in it.
I had a ford T-bird from the 70's that stalled out everytime it rained (the dist. is on the front of the motor of Fords). I sealed up the cap and had no more problems.
*edit, where the hell is Rolla at??. I am close to the KC metro area.

Rolla...well I-44 runs straight from StL to Springfield, and Hwy 63 runs from Columbia to Jeff City to straight south. Rolla is where those two intersect...probably about halfway between StL and Springfield.
Its dry/sunny here, still wont crank. Ill try it again this afternoon...See if it cranks. The last time this happened, once the weather dried out some, it cranked right up.
Its got a distributor on it...I took it off last time it wasnt running, and it appeared to be dry. However, Ive had the car for about 2 years now, and no idea how old the cap is. The rotor looks to be fairly old too.
Just replaced the plugs (NGK) (gapped at 0.039 in.) and plug wires, the precious set look to be very old. I do actually get a good strong looking spark when I try to crank it, checked that last night.
I dont know if it makes much differance, but the old plugs are bone white, and from what Ive heard that means its running pretty lean...
