Getting on the highway My car just died,and would keep blowing every ecu fuse I put it.

My 02 sensor wires where melted 2 days ago and need to check that first.

but could a main relay cause this problem, eversince I put in my new injectors and walbro pump the main relay acts funny. It wont start after its been running if I shut it off and restart it within 5 mins.

anyways Im in a rush but any help would be great.

I have a multimeter and a continuity tester, how could I use these to find my problem

 

check to see if u have any loose grounds/wires at the main relay and by your ecu that was the problem for me.

 

definetly check you o2 wires, i kind of had they same problems and it was my secondary o2 sensor wires. they kept shorting to the exhaust and shift linkage.
sometimes the speedo worked sometimes not.

 

thanks for the input guys, im just waiting for some daylight to fix this ****, then I can go boost again!!!
