92 Cavalier starter problem.

[beeswax]

Hello folks,

I've had a weird problem for awhile now.

When I turn the ignition, sometimes I will get a single click sound coming from the solenoid on the starter. Sometimes it will start right up perfectly. I've changed all the battery terminals, ground strap, and replaced starter twice.

I was thinking that their might be teeth missing on the flywheel, but I checked that and all the teeth were there. When I swapped the starters out, I've tried different shim configurations, currently I'm using the original shim, and it seems to make contact with the flywheel perfectly.

I think the problem is electrical related. The wires connected to the starter solenoid and starter motor looked clean. I was thinking of checking the fusible links next.

Anyone experience this before, or any suggestions?

Thanks

check the engine to body ground strap, with a car that old that one may have wore thru enough to slow the current flow, if you can't find it run a ten gauge wire fron the engine to the neg battery terminal ( this wire is a temp use only )and see if that helps

the oem strap will go from the fiewall to the engine or a tranny bolt

Thanks for the suggestion.

I've put in a new ground strap already thinking that might be the cause, the old one was corroded and useless, but the new one is in good condition.
