another gti6 not starting

[kentiiboii]

bloody car has done it again...

was running perfect! Tuesday morning went to car started it up to find where power steering is leaking (but didn't touch anything). shut the car off and come back to it later on after getting rear caliper from scrap yard. fitted rear caliper, bled the brakes then went to start the car to test the brakes but car wouldn't start.

ignition is coming on, engine is turning over, fuel pump is priming, were getting fuel to the injectors but the spark plugs are dry.

weve tried changing fuel pump relay but no difference, checked the fuel cut of switch a thousand times, checked all fuses and relays, changed batteries in keyfob so we could turn alarm off but that was never a problem before and weve even tried using easy start but still not firing.

going to get diagnostics on it soon as I find where it is.

anyone else have any ideas what it could be? someone might of had something similar.
I think it could be crank sensor and ill be changing that in the morning for one of the other gti6 (hopefully its a working one).

could do with it sorted asap as car is booked for mot on Saturday.

Sounds stupid, and might not relate, I had starting issues with mine when my fuel filter came loose. It would crank etc but that's all wouldn't fire

Crankshaft sensor or map sensor

will keep that in mind, I thought blocked filter before we started but were getting fuel.

Crankshaft sensor or map sensor

If I havnt for that how can I go about getting one and making it work to the car? Will be recoding wont it?

Think you're right there.
Locked ecu caused by the immo chip being lost.

[kentiiboii]

Cully I think you might be a legend! I swapped case on key for the better one I had lying around. Immobiliser chip is still there. On way to garage now to try it.
