Hello, I am in need of assistance,
I have a 1970 ford fairlane that has developed a problem. When you go to start the car, it fired up and runs, as long as you hold it in start, as you turn the key to the run position, it will die completely. I replaced the coil, ignition switch and what I thought was a ballast resistor (instead it was a 20 amp circuit breaker going from the starter solenoid to the ignition coil and the car was running fine with it installed and the car had no ballast resistor installed in the old wiring harness). So now I do not know what to do, the car has a new painless performance customizable wiring harness so I think I may have knocked a fuse loose but not too sure on this. Please help me.

 

Hi
Maybe you should look at the ignition switch.. and don't hold it in the start position unless you want to buy a new
starter or ring gear..
FYI. there are 2 circuits for ignition, one is the start, it engages the starter, when you release the key it is in
the run position which goes only to the coil..
I'd say if she starts, but stop when you release the key, then your run circuit has a problem...
You can check this by turning the key to run, then using a volt meter, check the voltage at the coil.. you should have
12v on the + side don't try to start the car while doing this... ouch..
on the ignition switch you have 3 different wires 1. power, 2. start, 3 run... again check voltage at the run wire..
I hope this might help
Best
