Car wont Start

[flev93]

anyone how to bypass immobiliser as mine has kicked in for no reason..

i havent changed ecu or key or anything..

i got no spark, fuel pump not even priming etc

i got power going to all the relays and coming back out.

but seems like the immboiliser has kicked in and stopped everything?

Answered you query in the thread above.

To your answer, I didn't unplug the immobiliser.

But the loom and ecu has been off the car before when engine came out for rebuild?

When we did that it wouldn't run, it would start then die after 3seconds.
But we put code reader on there cleared like 20 errors and it run.

But now I got nothing spark or fuel but all relays have power.

earths

[flev93]

only one earth i took of that was the gearbox one:/

[CALLUMSAMUELS]

that could easily be the culprit, i would give it a sand down make sure its proper good connection

[flev93]

dont you think it could be immobiliser?

and what about the earths on starter moter?

[CALLUMSAMUELS]

could be, i would of thought the key light would of been flashing tho, if you have locked the ecu you can only really get the ecu sent of to somewhere like bluehawk electronics for them to completely remove the secruity. before you deem that the issue tho i would go through all the other bits like the earths, all the earths, the earth strap from battery to chassis and gearbox proper sand them back to bare metal

[flev93]

its going on standalone anyway. will that bypass it all?

[CALLUMSAMUELS]

I think so

If the key light isn't flashing it's not the immobiliser that's the problem.

If the immobiliser was locked the correct key and ignition barrel transponder would unlock it.

Fuel pump still primes and starter motor turns when immobilised, it only cuts the ignition and fuel injectors.
