Car cranks, no spark to plugs. 1982 Buick skyhawk. How do I trobleshoot

Make sure battery has a full charge and battery connections are all good. Have a helper crank it while you check for spark at the plugs. If spark everywhere, check fuel pressure.
Is this vehicle computer controlled?

Hope this helps

not getting spark if it wont start with starting fluid im guessing u got distributor on that old of car may need cap, rotor and pick up coil

under dash aside of brake pedal

BAD COIL OR IGNITION MODULE INSIDE DISTRIBUTOR RUN OHM TESTS TO VERIFY

it sounds like there is really only one more component to check - check the rotor in the distributor cap and cap itself.

c...

The check engine light ,has to do with ,is the gas cap tight? or the engine is burning RICH and the computer kicks it LEAN and then it kicks back RICH ,then it doesn't know what to do so it puts the check engine light on! it is ok to drive,fuel mileage may be lower. in a lot of cars it has to do with" ignition key cycles" put the key in ,turn it on crank it let it run,turn off ,take key out ,that is one cycle i know with some cars its 20, and some others its 54,your car may have what is called a OBDII .,plug ,under the dash ,a code reader ,could read the code and clear them ,THERE is something else ,that may work with my skyhawk,buick to clear code i could unplug the ---- negative side of the battery and wait 3 minutes and tighten it back on,you'll have to reset your radio

check your injector fuses and also your crank sensor

have you replaced the fuel filter? If it is clogged it will restrict flow.

change the crank sensor.No the ECM has no internal oil components
