Normal
you have a curcuit opening relay that is a dual relay. One side is trigger by the air flow meter. it turns the fuel pump on when it senses air flow and if the temp is cold it also triggers the cold start injector. next time it won't start, leave the key on and check power to the injectors. (blk wire - red tracer) they are fed direct from the switch. If you have no power there, look for a bad ignition switch. If you have power at the injectors, look for power at the check connector as I said before. That will tell you if the efi main relay is working. (or bad wires to it) If you have power there, then check all powers and grounds to the computer. Let me know if you need pin numbers/wire colors for them.
