computer problem - Ford Forums

Is anyone familiar with the computer pin out and could you tell me if the computer has 12v going out on pins 37 & 57 or is the 12v coming in.
This is for a 88 turbo coupe computer and engine in a 92 ford mustang. Also if I don't have any power on these wires does that mean my computers bad.
thanks

Power should be going into the ECU on pins 37 and 57. If you have no power on these, check your EEC Power Relay - either the relay itself is faulty, there is no power to the getting to the relay from the battery (fusible link), or the relay isn't getting a signal from the ignition switch. Grab a circuit diagram for your car and a multimeter - it's time to go hunting!

thank you so much I was on the track that I thought the computer was bad but come to find out while removing a plug I accidentally removed a fuseable link. I am up and running
Thanks again

Glad it worked for you - nothing feels better than a cheap fix (!?).
