hey i have a sierra sapphire rs cosworth 4X4
the problem started about a weekago the car would turnover but wouldnt fully start then it would, i thought it was the imoberliser for the car and then i got tht replaced now with the new alarm the car was still doin the same thing, now we hve found out the the ecu is playing around and the car is dead now i think one of the relays has gone any advise on to how to get this fixed or if theres anywhere where i could get a cheapish new ecu for the please let me know thanks coszee

 

probably not the ecu, try the large engine loom multiplugs aroung the battery area on the bulk head
