I have a 89 spirit 2.5 turbo and I just put a turbo intercooler with factory TII airbox and hoses. Well, I took it for it first test drive and steped on it a little and the thing just dieds?? I got It back in the drive way and it has a code 42. I noticed that the fuel pump was not working?? I know that it maybe the ASD relay. I did just change the head gasket and maybe I have some vacume hoses messed up. Maybe it overboosted?? Please help!!!
