Issue with A9L...

Hey guys,

I usually post over at vintage mustang forum, but thought I could reach out o you all for some help.

I have transplanted a 5.0 engine into my 66. I have an A9L computer hooked up with a Ron Francis harness.

Everything appears to be powering up and I am getting fairly typical soft codes, except #96 which is fuel pump secondary circuit failure. Also, my fuel pump is not powering up at all when the ignition is switched on.

Any ideas? I did do a self test and grounded out #22 and the fuel pump switched on with no problem.

Check continuity from ECM pin 22 to the relay ground.

Thanks! I really had a hard time getting the 60 pin connector, relay bank, and fuse block thru the hole I cut in the firewall. There is a chance that I damaged a connection. I've looked, but I'll pull out the meter to double check.
