Saxo none start

[parapilot]

hi Guys,

I have a saxo VTR 1.6, none start. It has a flashing key light, cranks but wont fire.

I have tested key and reader, they are fine. Lexia sees the key, and states key code valid. the key also re programmes in. so im ruling out immo fault.

I have removed relay under ECU, i have 12v to 3,8,11 and 15, but with the ignition on i do NOT have power to 4,5,6,12,13,14.

Also no power going to fuel pump, during ign on or crank. when 12v is applied direct to pump, it spins so not faulty pump

Checked fuses.

Any ideas??!! :wall::wall:

Thanks
Jamie.

the flashing key light is the immobilizer light hence why it wont start get the ecu unlocked or buy a already unlocked one :y:

This ^.

The immobiliser is on. Quickest way around it is to buy an unlocked one from someone on the forums here. They tend to go for about £40-50.

Sorted.

lexia is telling me the key is valid, and engine start permitted as regards to the valeo immo box. the ecu does not have power, so replecing it i cant see helping. I will have the kit to unlock / remove immo on the bench so will do that if i need to, but im convinced its wiring / relay somewhere!

ill replace the multi function relay first see if that helps!!

cheers
Jamie.
