1983 olds 5l. 305 ci. hei? carburator

i was driving along and it just konked out like its not getting spark maybe. hard starting and runs weak if i dont hit the gas. i'm gonna replace the cap and rotor but is there a test for the coil? resistance maybe?

had an '83 Cutlass, had the same kind off trouble. It was the ignition module. When you take the top off the distributer, you'll see it. Just a thought.

there's many possibilities...

...but to answer your question about ignition coils...yes, there is a resistance test. for an HEI coil the spec for the primary winding is .5 - 1.0 ohm and for the secondary winding it's 6,000 - 30,000 ohms.

you could put a spark tester on it, they generally put enough load on the coil to rule out a weak one and dynamic testing is better than using an ohm meter.

when was the last time it had a fuel filter?

ign modules are testable at most parts stores.

perhaps you could give a more detailed description of what it does and we could offer more direct advice...

I agree with carguyinva that there are many possibilities and ignition wouldn't be my first suspect. Generally when a module quits, it yes or no with spark. When a coil goes bad, it's usually load that cripples it. I would start out looking hard at fuel supply AND QUALITY. I've seen water in the fuel act like that too.
