you will have to check that the ecu's vin is the same otherwise the bcm and ecu will conflict and probably just immobilise the car.

However if you have a fuel sender issue along with not starting, you should check your ignition barrel as alot of times the connections at the bottom are faulty which causes those problems.

We had a car doing the same thing, changed the ecu still did it.... turned out to be the ignition barrel.

thanks for reply, i changed full steering column and no good. when i try to connect vcm suite to the vcm with key turned on it says can not detect turn key on. when i plug another vcm in it connects and dtc on scan says immobiliser not connected. am i able to change vin on vcm and pair vats. or is there any thing else i could try?

thanks

did you check the wires at the bottom of the ignition barrel itself?
