ecm relay problem ok people, here is the deal. I have an 86 5.0 with the H.O. engine. it has the DA1 computer in it. the ecm relay some how got water in it and was bad. I replaced the relay with a new one and then the computer. it still didn't fix the problem, but then i realized that the ecm relay was't clicking. I then removed the cover off of the relay and forced it to contact, the car started up and purred like a kitten, but as soon as i let up on the contactor in the relay the car stalls out. the best I can figure, is the power wire that activates the relay is bad or the relay is bad. how do i trouble shoot this problem?. does anyone know witch wire makes the relay work. I did notice that the new relay has a circut board and the old one doesn't. I don't know if that is how they make them know or if sompthing is wrong. |
