Well, I'm trying this cuz haven't had any luck on the web.. I have a F37F-12A650-VB PAN1 ECM for my 1993 Ranger.. I had replaced it about Six Years ago with this one , A Cardone 78-5507 rebuilt one, but the last couple of months started running like(and I thought) I had gotten water in my Gas...NOT.. after extensive checking on ALL my sensors, and chasing a -25 LTFT on my Scanner, I took out the Computer, and looked inside to find I have a Resistor that is FRIED..
The resistor burnt so bad I can not See the Bands on it to replace it with a new one...I can not see spending another $150.00 plus on another Rebuilt one if I can fix this one for $.05 cents....I have enough Knowledge about electronics to be really dangerous, but this is a simple fix looks like...I did in the past have a O2 go bad, Mass air that also took a crap, couple months ago, and a TPS that had a intermittent problem months ago also,two years ago has a Crank sensor go out too...So I believe one of the past failures caused the Resistor to go open, and it was intermittent and then got worse..
I am really hoping SOMEONE on here has the same ECM and can take the top off it and send me a clear picture of the resistors so I can see the Bands on the one I need to replace...
