Default Re: Burnt plug wires

You said it was overhauled 30k ago, very doubtful on chain. You can also check the chain by pulling the plugs, inserting a piston stop in number 1 cylinder hand turn engine till you touch stop note position of timimg mark relative to damper, rotate opposite direction and recheck mark, should be the same within 3 to 5 degrees. Did you carefully check the electrical connections to the distributor. There maybe two connectors, one of which is the ECM connection

That is great advice. I will do that. Thank you.
And yes we checked the wiring but couldn't find anything. I was debating on checking again but the mechanics said he thinks its mechanical not electronic. I am having him replace the ecm now since I dont have the computer to reset it.
