Hi, So I have an 1987 E30, a car which I love and have been though a lot with, and if you have a e30 you know exactly what I mean.
My new challenge is quite staggering, so I need some advice.
Car started to hard start and then starts on and off, until crossing an intersection and the car completely shut down on me, I did all the regular test, checked for spark, battery, I had installed new crank shaft and reference sensor but still check them all ok. Also the OBC and the OBC relay, all ok. I discovered that it was indeed the fuel pump that was running and stopping so I bout an after market msd fuel pump pressurising will. How ever now the car wont start at all it swings quite strong but no joy. and the hum i would usually hear from the idle air control valve and have switched it out with a fully functional on. still no joy. I am now at the conclusion that its a main harness problem and not engine harness because everything else is working and before everything else was working. Am I missing something??
