Alright ladies and gents, i acquired a 97 NA for 500, only prob was that it wouldnt start. After looking it over I noticed that it will turn over but wont start. Further investigation yielded no spark. First Natural step was check the Batt. - all good, Starter - All Good, I replaced the leading and trailing coil...still no spark to the plugs...what the hell is next? Where do the coils get their power? This is reall starting to **** me off...Any suggestions? Help needed ASAP...i need to get the car moved...



Thanks In advance..

uh, 97 NA.. does not compute.. maybe you meant 87?

the coils get a 12v power and a signal from the ecu, and the ecu gets its rpm signal from the crank angle sensor, it kinda looks like a distributor without a cap

I'd suggest taking out a DMM and checking the CAS to make sure it's oke (ohm testing it) If that's oke I'd head to the ECU and check the ECU to make sure it's getting signal from the CAS. If it is.. check to make sure it's sending out signal to the coils. if they are.. check the coils make sure they are recieving the signal.. Check the coils resistance.. is it not grounded properly ect. this is all fun Digi multimeter time.

d/l the factory service manual it'll tell where you to check and what resistances & voltage you should be seeing where.



*edit* i'm slow mike beat me to it.
