ep82paul Posted May 2, 2016 Author Share Posted May 2, 2016 Open the diagnostics plug and link out B+ and FP, when you sinfo itch the ignition to position 1 the efi relay should come in and the fuel pump should run. That will check the pump is ok.If it does not then the fault could be the 15A efi fuse or efi relay.If it does run then but not in normal circumstances, then it will probably be the circuit opening relay. But I dont think this relay will close until you engage the starter, then it only stays on for a few secondsFound this on gtturbo forum written by wee john very good info just tested it now fuel pump works car started straight away so my relay under glove box is broke Quote Link to post Share on other sites
triple j Posted May 2, 2016 Share Posted May 2, 2016 (edited) the circuit opening relay it could be the problem, pull the cover off it and check if there any dirt in there, u should be able to here it click when turn ignition on Edited May 2, 2016 by triple j Quote Link to post Share on other sites

Stu Posted May 2, 2016 Share Posted May 2, 2016 I would check that you have the dizzy plugged in correctly before looking at the circuit open relay, especially as you have had the dizzy out and it was working before. The ecu triggers the circuit open relay only when it senses that the engine is turning over, so if the dizzy isn't plugged in the ecu wont read any engine rpm so it wont trigger the relay/pump. Check to make sure the pin inside the plug and not too wide so they get a good contact with the dizzy terminals. Quote Link to post Share on other sites
