Question about Oldsmobile Cars & Trucks
I keep losing spark, replaced cam sensor, cam interuptor, timing chain, crank sensor, mass air flow sensor, tps sensor, coil pack, ignition module car ran abot 100 miles started shutting down again with no spark, starts again after sitting,
Generally the cause of an electrical component to fail is high heat or extreme voltage load.
Is the coil pack and module getting too hot from the heat of the engine ?
Is it shorting out because of oil or wet surfaces ?
Could you be loosing voltage to the module from the key switch ?
Are you loosing ground signals from the computer ?

Best to do a fuel pressure test, pump might be weak and dosent show up until it gets gets warm. Best to do the test after it quits again when pump is at its hottest. If you havent done it yet chg. fuel filter too.

next time it won't run after it heats up, spray or pour water in crank sensor and see if it will start. I have seen new crank sensors go bad.
