Hi guys got a small problem had my escort rs turbo stripped down for 2 years. Rebuilt it and Finally got it started the other day it ran for about 5 mins then cut out and won't start again. There no spark got power to the coil got power to the dizzy I had a spare ECU tried that and it started on the button then exactly the same thing happend cut out now it won't start with either ECU. Could I have blown the ECUs somehow. Iv searched everywhere to find the problem anyone had this problem or can help me out thanks guys.
