I've been reading on other forums about using factory parts instead of the stuff from parts stores. Some results from the parts store components were quite bad ! I may try an OEM crank position sensor before getting into the wiring etc. The service manual says that the wiring etc from the CPS to the IGN module is suspect if it wont run !

After reading about after-market parts failing fairly soon after using them, I'm wondering if I should try an OEM crank sensor. It's easy enough to change. I haven't checked the FSM about the clearance HotZ28 mentioned. Wasn't aware that it is/was adjustable (??)

IIRC correctly, (been a long time since "93) but I think the CKS on that year was the non adjustable type, plug & play type! There could still be a malfunction in that wiring circuit.

That's what I'm thinking too. Hot Z ! That harness is like a snake !! May have to pull the alternator etc to get at access to the harness, for an inspection. I suppose the loom would have to be opened to get a look for wire damage etc.....And of course you are right..it's been a LONG time since "93 !!

I ordered a factory GM crankshaft sensor. I see on some forums that some aftermarket parts have a failure rate more that OEM stuff Since the crank sensor is easy to change, I'm gonna change it & go from there. I'm going to wring out the harness from the sensor to the IGN module also...

I just bought a factory crank sensor, after reading about aftermarket parts failures. Luckily that part is fairly easy to replace. Buick doesn't run, it's outside, so I'm waiting for the temp to get above 20, to work on it !!:giggle:
