My 1987 Turbo II won't start and I know its not flooded. I removed a plug, grounded it and it makes only one spark each time the engine starts turning!?!?



The problem started a while ago but happened only once in a while. It re-appeared more and more frequently to a point that the car now starts only on rare occasions.



I did the Ohm test on the crank angle sensor and on the coils and everything reads OK!



CAN SOMEBODY HELP ME, PLEASE?!?!?!?!?!

bad coil or bad crank angle sensor ?

gusman

As I just said, I checked all of the coils and also the crank angle sensor as described in the Haynes manual by checking the resistance and it gave the proper reading. To make sure, I also checked the ones I got on my 1986 GXL that I keep for parts and I got the same readings.

vosko

oops sorry didn't read that...... maybe spark plug wires are bad ?

gusman

I already tried switching them with the old GXL and it made no change. Maybe it's worth a try buying a new set.....both sets are old!!

It's an intermitant problem right? Sometime it works, sometimes it doesn't?

gusman

Exactly!

And it's getting worst.

phinsup

Well then if you tested the coils and the crank angle sensor who is to say they aren't still bad... could test good then be bad then be good again, I would swap the coils from the other car, see what happens.

gusman

Thanks for the advice. I'll do the switch today and let you know this evening if it worked!

I had similar problem, but after replacing wires, cleaning plugs, deflooding engine, car started right up. I made the mistake of only pulling the trailing plugs when checking the status of the plugs, they were spotless. I later pulled leading and they were caked with crap (my oil control rings leak alot) took a dremel with wirebrush to the leading plugs and they were good as new. Even after cleaning the plugs though I had to deflood the motor for a long time, all the attempted starting with no spark had flooded it real bad. I was checking my spark with an inductive timing light, which was a bad idea apparently. What I get for being lazy.
