Hi. I am from the UK and love american cars....Until they go wrong

Could my PCU/PMC be dead? How do i check it?
1989 5.7 IROC Camero = No spark at the coil HT. Got power into it but
Not pulsing.
Fitted new coil.
Engine does turn over.
Fuel pump is working.
All wiring feeds show 12volt.

Was running sweet. Switched off. A while later, restarted, then it just stopped. Not been able to get it running again...I HATE ELECTRONICS.

Thanks

 

No, not the ECM. The distributor is on it's own during cranking (turning over).

Odds are either the ignition module died or the pick up coil went open.

Hi RBob.
Have sent you a private message.

 

The pickup coil is under the cap, rotor, and star wheel of the distributor. It plugs into the ICM. Unplug it and measure the resistance of the coil. Should be about 800 - 1100 ohms.

OK, got it. Will check it out this weekend.

 

sorry had to do it :P good luck with your camaro sir

Looks like you hit the nail on the head.
Pick up coil, how on earth did it get into this mess

I must say, relative to your thread title, that distributor is dead. Need to replace a bunch of parts...

Complete new dizzy on order. Should be here on Tuesday next week.

 

New dizzy fitted and Hey Presto, all running sweet. Thanks for the info from site members.
Now for the cosmetic clean up.
