My 1992 Bonneville will turnover but wont fire. The carr has 205,000 miles but has been running great. Parnelli Jones was the origional ower so I would like to keep it around awhile. I recently replaced the Fuel pump and filter because the pressure was low. Next I checked for spark and got nothing so I went for the ignition coil and replaced the module but still no help. I also checked all the fuses and codes in the ECM and they all checked out. Next I suspect the cam or crank sensor but am reluctant since nothing was logged in the ECM. Any suggestions for a perplexed rookie?

I am not sure but that 3.8 engine had a penchant for having a bad crank sensor. it is behind the crankshaft damper. The damper and the sensor both come of easy.

Suggested Repair

Replace the crankshaft position sensor located behind the crankshaft damper.

Conversation Summary

A 1992 Pontiac Bonneville with high mileage cranked but would not start. The owner had already replaced the fuel pump and filter, found no spark, replaced the ignition coil and module, and verified fuses and ECM codes. An expert suspected the crankshaft position sensor behind the damper. Replacing that sensor restored starting.
