Re: HELP! Stalling as soon as the engine gets warm.

Thanks everyone I just wanted to update you because I got her running! I was up til 3am last night I voltage tested all the terminals and relays, cleaned them all, took off the distributor cap and uninstalled the ignition module and tested all the connections. I cleaned it all and reinstalled it and cleaned the pickup coil connections. This morning I got it and she fired right away, it ran idle for 35 minutes without dying and my fan went on too. Must of been a loose connection it looked like the pickup coil connection was loose too.

Voltage key on:

Power to coil - 11.66v

From coil to ignition module - 11.68v

4 post terminal to/from module - 0.98v

Ignition module 2 prong out to pickup coil
When connected:
Prong 1 - 5.53v
Prong 2 - 5.56v

To fuel pump relay - 12.29v
To MAF power relay - 12.29v
To MAF burnout relay - 12.27v
