1999 Ford Mustang Q&A
1999 Ford Mustang Question: I hate computers in cars!!
other than clear old codes, is there anything you have to do to a replacement passenger side computer to get it to start the car? We have tried THREE and none of them would turn the car over. (two were close matches the 3rd and exact match) Plug my original back in and the car would start. But with fuel pressure that varies from 5-35lbs. I am just sick!! - 99MustangOwner
aside from what junk yards tell you, you cannot swap computers without re flashing the unit to yours. that is assuming the junkyard unit is anygood. start at the beginning. what is the no start issue? I see by your fuel pressure readings that there is not enough pressure for it to run. that may be the fuel pump failing. Do you know if it has any spark?? Roy - mastertech6371
