1988 Oldsmobile Delta 88 Royal V6.
Service engine soon light.
GM Computer codes = no
Replaced water pump and thermostat replaced.
Replaced brain, cam and crank sensors, and electronic distributor pack, ( part with the plug wires ). had the ignition module ,i think that's the name, checked and was told it was good.
Question: After my engine warms up the car shuts off, like the key was turned off, then wont fire over for several hours. it cranks fine but wont fire. i know were not getting any spark when this happens. After sitting several hours it will fire up, but only till it warms up.
Answer: OK. Two things. With the check engine light on, you MUST have the codes scanned to see what system is setting the light. This may help in diagnosing this problem. Aside form that, just because an ignition module tests good, does not mean that it won't fail when it is on the car, and hot. Even if quickly removed when the car is not starting, and tested, then re-installed, and car still wont start, does not guarantee it is good.
Tests of these modules are not always definite. You would also need to check for fuel injector pulse signal from the computer. If you have no spark AND no injector pulse, then i would suspect a wiring problem between the crank position sensor and the ignition module. If ONLY spark is missing, then i would suspect the ignition module or wiring problem to it.
