1G boost gage doesnt work car wont run...

Ok this is all i know about this problem. I was driving along at 50 55mph all the sudden the boost gage quit working and the car stoped running. Tried it again after unhooking battery for a few min. Cicled the key and the boost gage activated so i started it. Ran fine for about 2 or 3 min the gage quit again and the car died. Got it home went to put it in garage started it to back it in gage working fine. Car ran for prolly 25 min never had a problem. Shut it off and unhooked the battery. It sat for a couple weeks and i fixed a boost leak and am trying to get it going. Now the gage will not work and car wint start. If you try to start it a couple times and let it sit for a min it will try to start but dies... im lost.. any ideas would be great. Thanks guys

Sorry to hear it's going to be so expensive. I told you back in May that both ECU's needed capacitor replacements.

Yes i remember. When i found the leak i was hoping id get lucky. Shoulda just bought one back then.. just one quik question for you. What is the "mpi" what does it stand for and what does it do?

MPI = Multi-Port Injection

Typically refers to the MPI relay. Here's a good read about everything MPI-related: 1G basic ECU MPI circuit function
