I thought of another check, you probably already did this though. Measure the resistance to ground on any of the fuel injector connector ground pins. It sounds like if that is even 2 Ohms (I picked that number out of the air), you will get that code. And the ECM should compensate for it by sending more power through, thus having no noticeable decrease in performance.
Are those the obd codes you are getting (p1237-P1242)? Maybe the fuel pump relay? Does it run then? Is there anything you notice about how it runs? Maybe a lag when you hit the gas, or bad gas mileage? Have you checked the fuel pressure?
