Immobilizer problem

[rich30mex]

Got up this morning and went to take the car to pistons in the park but she refused point blank to start. Luckily Mr armstrong had his tech 1 with him and was kind enough to lend it to me. When plugging it in I got 2 error codes the first was mass air flow fault the second was immobilizer code 145. I cleared them both but the immobilizer one went for immobilizer code 145 to immobilizer 144 and the car still will not start. Anyone know what is the best route from here on in is as I'm sh1t with electrics

Thanks

Now managed to get all codes removed and nothing showing but still no joy I have given up on it for the night and took the battery off going to see if the "man reboot" (removing the battery blowing on it and reconnecting the battery ) will work

Does the engine management light flash when your trying to crank? (I know the engine isn't cranking)

Do you have a second key you can try to rule out the chip in the key being the fault?

[rich30mex]

No mate it turned over but will not start

[Cliff]

Sounds like either the collar isn't recognising your key, i.e. Chip fault or the collar isn't sending the right code to the ECU i.e. Collar fault

[rich30mex]

right lets up date this

batterys been off for 38 hours cleared all codes on the ecu but still no joy. I can not hear the pump priming and theres no fuel at the fuel rail

[Cliff]

It's the immobiliser IMO - did you try with a spare key chip to rule that out?

[rich30mex]

Yes I did mate still nothing I'm waiting on a non immobilized ecu to try that see if that solves it if it does I have been told to get a set of chips from Courtney or some where like that as it remove the immobilizer from my ecu

[Cliff]

Could be the collar at fault or even the ECU - let me/us know how you get on with the replacement

[rich30mex]

No joy with the none immobilizer ecu trying a new crank sensor tomorrow

[Allys Cally]

your saying your not getting any fuel but are you getting spark?

[rich30mex]

Tbh not even looked for spark

Sorry to hear of your woes rich...

Was the alarm triggered prior to the no start issues? I'm not 100% but I would suspect the alarm is on a separate circuit to the immobiliser and would take precedence. Simple lock/unlock should satisfy if so.
Another thing to maybe check are the contacts at the diagnostic plug itself... dirty connections, wet etc.

Good luck

No mate there was no alarm and already tried the door lock and in lock I'm waiting on a crank sensor to see what happens then bud

[cal16v]

Just another thought... trigger the alarm and then try the key trick again. Nothing to lose
