Long story short - changed ABS sensors, all went well, ABS lights on dash out etc.
Started truck and all ok. Put wheels back on. Tried to start car - won't start. Sounds like it's immobilised. Pulled hoses to fuel filter and cranked - no fuel.

1) Do these trucks have fuel stop solenoid valve?
2) Where is immobiliser?
3) Please please please help me!!!!
