TDC697 -> ECMB Fuse Blowing (10/1/2007 9:57:55 AM)
|
My sons 1990 G20 van is not getting fuel at the TB. The fuel pump runs for about 10 seconds after the key is turned. Too long right? I thought the pump was not supplying enough pressure. So I changed the pump and filter. Same problem. I then took a look at the fuses. Both 10 amp fuses ECM1 and ECMB were blown. The ECMB fuse blows immediately when replaced. I replaced the fuel pump relay. Same problem. I looked at all the wires for shorts. One wire leading to one of the injectors was flattened a bit by the adopter ring(or spacer) resting on top of it. Insulation was not pierced though. The van has an alarm system that doesn't work anymore. Your help would be greatly appreciated.
