Fuel pump keeps priming after Air pump Removal + Wiring

Isnt fuel trigger by ground.
Have you checked a short to ground from the PGM-FI relay on this?
If you want to you check continuity to ground from the ECU trigger pin & ground, to see if the ECU is in fact changing state.

After talking to another tech, I was thinking the same thing. Looking back on my "adventure", I'm pretty sure I had a few of the grounds unmounted after removing the wiring. I plan to remove the wires I have cut, reinstall the harness and bolt the grounds down properly. If this doesn't work, I still have another harness that I have not cut into yet. Will hopefully get to do this this week. I'm so ready to get back behind the wheel.

Ok, I have good news to report. Remaining Air pump wiring removed from harness. Installed harness. Starter works properly. Bad News: Fuel pump still priming. (this is the original harness from the car that I had hacked into, still have untouched harness as backup.) I have found a PGMFI Relay troubleshooting guide in the service manual. Running through this guide is my next step. I will update as I have new info to share, good or bad. Thanks guys.

After doing a lot more searching online with others that also had a "flooding" issue and would not start, It seemed the ECU was their issue. Even though mine had been given a clean bill of health, I ordered a used one on ebay. It has been delivered today. I will update with what comes about.

I plugged in the new ecu, put the key in the ON position, applied fuel pump fuse, fuel pump kicked on as it should for priming, then......... the fuel pump stopped priming....... Survey says, it's the ECU. I have contacted SIA electronics for a refund for the remainder of money spent with them. I have not started the car yet since this ECU is not programmed to my keys.
