I cleaned all the grounds checked both in line fuses any other obvious locations left to check? Tried bypassing the switch by running a hot wire direct to the coil and still acts up? Thanks for the help

I wonder if my dual relay went south on me. When the car is running if a feather the accelerator I notice that the relay will click and power to the fuel pump will turn on and off momentarily (green and black wire cycles). Also until it starts there is no power at the green and black wire and the engine quits when it the power goes out but all my ignition still has power. VICKs advised that it is likely the dual relay getting funky. I likely helped it along a bit after I had the AFM rebuilt I did drive it for probably 5-10 miles with the idle set too low and causing the relay to click on and off constantly at idle. Any thoughts???

It is the AFM that signals the relay to close. when you are feathering the gas, you are moving the AFM. It sounds like you may have a signal issue from the AFM rather than a dual relay issue. Since the AFM was just rebuilt...... Anyhow, if you get a new relay and that doesnt solve the issue, then you have a spare relay.

Keep blowing ignition modules...any ideas?

My 81 FI spider keeps blowing ignition modules? I have replaced many of the electrical/FI parts.
Now I am lost! Really need help trying to figure this out.
Thanks, Marty
