I'm having Fp problems. Relay works and engine runs when jumpered from test connector to ground but won't switch to ground KOER. been testing grounds and they all show a little over 1 to 1.5 ohms. is that enough to cause this condition? can I check FP resistance at the Pump connector at the rear of car? Getting 12 volts everywhere I should at relay inc, prime circuit. still no ground at pin 22. If I can run codes, is it safe to say my computer is good? Manual trans
