No Spark!!!!
Car just died at a stop sign Friday night. Cranks and Cranks but wont turn over. I know its getting fuel the pump turns on and Im getting fuel in rail.
Checked for spark yesterday and there is none at the Distributor. How do i diagnose this problem and track down the cause
I did replace the cap and rotor last year and have only put about 10 miles on the car since then they are still like brand new
possible ideas right now
coil
ignition module
bad ground
blown fuse
ECM
not sure let me know
thanks for any help

Re: No Spark!!!!
id check for spark at a plug first. pull a plug wire off the plug and check it there if no spark at all id bet its the magnetic pickup trigger in the distributor if you have another one laying around slam it in and try it if it runs or sparks it will be the pickup.there easy to change just knock out the pin in the gear and slide out the shaft and bolt it in hope it cures it

Re: No Spark!!!!
Seems to be common these days!! I have the same problem right now and have narrowed it down (hopefully) to that. Posted in another thread too, same topic hehe!
