1984 Pontiac Trans-Am
Symptoms:
Car starts then if you switch on lights/ heater/ radio cars stalls then will not start. When you turn the key into the run position the chime goes off but ever so faintly.

Leave the car for a week and it will start and run but as before switch anything else on it will stop.

I got it back from the mechanics after it sitting for four months having parts replaced or repaired after a ski going through the drivers window. took it for a run to work and it overheated because the thermo fans wer not wired in.
It ran alright after reconnecting them then the next week after not having been run stalled at work and took four weeks to get it restarted after changing the coil and ignition module with two hours of turning over and flames coming out of both ends.
Since then has presented with the above symptoms.

Has the ignition switch been overloaded and does it need to be replaced or is the alternator cactus?

Thanks guys

 

Sounds like a bad/dirty/corroded main ground cable or terminal.

 

I agree, sounds like a ground issue.
