Short version is I have a 90tt. It was running great and then died on the way home one day and would not start again. I get it home and it runs great for a week. Does the same thing again as once home it ran fine. I go away for a week for fork and then went out and now it hasn’t started since. This is what I know
Has Wirespec harness new style PTU, old style CAS, new style Injectors.. Chipped ECU
Getting fuel and fuel pressure looks good
Sellin duel May light comes on and goes green
Not getting spark so I started at PTU
I test ok on pins 1-6 according to FSM
Little confused about the CAS
Removed it and spin you can hear the Injectors cliblack wire on left is ground, battery voltage on the black, white strip, whit is 5.12 volt black on the right is 5.12 bolts
Replaced the relay same result
Confirmed fusible links good
Borrowed a PTU just to be sure
ECU is talking to datascanI am starting to think ECU but not sure if there is a test or way to cofirm
