R33 GTR Won't Run - Low injector pulse

[lanky71]

Hi,

So after towing my car on a car trailer it started to run really rough, it went to an alarm installer and got immobiliser, alarm, tracker installed but two days later it wouldn't even run.

It kicks over but engine just won't actually start.

The injectors are getting very low pulse and the crank angle sensor doesnt have a heap of spark when turn manually or via ignition, we've already had the alarm guys test it and they are adamant it isn't the immobilizer causing any issue.

At the same time the spark plugs are now fouled, and two relays in the boot connecting to the twin fuel pumps have blown as well.

Any ideas where to start looking?

The ECU is a black box and there is a eflex sensor and AEM AFR cut in place which reports but then when trying to crank says sensor offline.

Hi mate, sounds frustrating.

i would check the following:

- Alternator 

- Coil packs / spark plugs 

- Hosing to air intake and engine 

- Turbo gasket 

- Fuses 

- Damaged or disconnected sensors which the ECU had picked up

Something may have been accidentally disconnected during the alarm/immobiliser install or it might have short circuited something.

Or it could have been just coincidental that something has gone by over time.

Good luck.
