I've searched the threads but didn't find an answer.
I have a 93 Mustang GT EFI, C4, A9P, Ryan's harness, new Idle Air controller in my '74. Error codes 23 & 96 (plus the typical 81, 82, 84, & 85)
I will crank doesn't start right away after sitting for an hour or so. Once it does start, it will run for about 20 seconds, then die. I can crank it over and it starts right up, but then dies again after 20 seconds. After reading some threads, I disconnected the IAC and Mass Air, it would idle (a rough idle) for well over 5 minutes, then while running I plugged in the IAC, with Mass Air disconnected, and it would die within 5 seconds. Disconnect the IAC, start up again let it idle, plug in the Mass Air, with the IAC disconnected, it would die again. I replaced the IAC and it still does the same thing.
Tonight, I got the error codes (23 & 96) as mentioned above.
23 = the TPS voltage, I have set this to about .95 but it doesn't stay there. The TPS isn't loose, but when I check the voltage after running the engine, it's off from where I just set it.
96 = Fuel Pump Relay not sending power to fuel pump. When I pulled the relays, there was a white/blue reside on the relay by the connectors (looked like dry windshield washer fluid). So I am pretty sure this isn't normal. Have I fried the relays?
I have tried reserching this to come to the answer on my own, but I am going in circles.
Any suggestions where to start?
