Bi-Turbo CFCA issue starts then immediately stops

[chrishay321]

Hi All

i have what seems to be a rather unusual issue with my 2013 2.0 Bi-Turbo CFCA Shuttle, it was driving fine them without warning it just stalled, and has not run since, it will start and run for about 5 seconds then stalls. there were 2 codes in after its initial stop but after clearing those they have not reappeared, and no other codes have been reported

the initial 2 codes were:
"mass or volume air flow circuit intermittent" and "ECM/PCM power relay de-energized performance - too early"

i have disconnected the MAF sensor (no change), i have changed the fuel pressure regulator (no change), disconnected the EGR (no change), disconnected the exhaust / DPF (no change) and disconnected the turbo / intercooler (no change)

i disconnected each injector in turn, injector 4 (no change), injector 3 (no change) injector 2 (it will not start at all) and infector 1 (will not start at all)

i did a leak down test and got hardly and fuel coming out of the injectors (but as it does not run for very long at all i assumed that was normal)

any ideas or suggestions would be greatly appreciated

thanks

Hi @chrishay321 sounds like a immobiliser fault. Have you tried the spare key? Do all the lights go out on the dash?

Hi Phill

thanks for the suggestion, i hadn't noticed the immobiliser light coming on, so i just checked it, it does stay off and there isn't the message on the computer saying its activating. i will look at theimmobiliser fuses though just to make sure

Did you manage to capture the 4 digit fault code? That would be worth searching.

I would also try cracking the steel fuel lines to each injector to make sure it’s getting fuel.

Will it run on brake cleaner?
