CEL- Check Engine Light
There is a input on the ECU that checks for FP power coming out of the FP relay during cranking and run.If the CEL is not on, that should mean you have FP power coming out of the relay, and your problem is probably the wiring after the relay.
Are you sure the injectors stayed open? Thats not very likely.Anyway FP diagnosis is extremely simple, since the circuit itself is simple.Grab a multimeter and start probing points on the above diagram, you should be able to locate the problem in no time.
