simonjob Posted January 1, 2018 Author Report Share Posted January 1, 2018 what do you recon it is could it be ether the crank trigger setting it off? Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 1, 2018 Report Share Posted January 1, 2018 You need to explain better what the problem is. Are you saying the ecu is staying alive after you turn the key off? Quote Link to comment Share on other sites More sharing options...
simonjob Posted January 1, 2018 Author Report Share Posted January 1, 2018 when I turn the key to the on position the fuel pump should prime for 3 to 5 seconds. but at the moment when I turn the key on the fuel pump is running for at least 1 to 2 minutes. I have checked the prime time in the fuel pump settings and it is set to 5 seconds. I was wondering is there is any other settings that could cause the pump to keep running on after the 5 seconds is up. could it be the crank trigger is setting it off longer or the cam trigger ?

simonjob Posted January 2, 2018 Author Report Share Posted January 2, 2018 managed to sort this one out I have found the pull up resistor was not on so it was picking up the trigger Quote Link to comment Share on other sites More sharing options...
