I've got an 4x4 cosworth with t34 with a 330bhp chip ( ecu has White mixture screw and L3 on chip). It's an Escort engine in a Sierra with 4x4 loom.
I have a problem starting, put new leads, dizzy, rotor arm, group a coil, ign amp. but still no spark. There is fuel, Could this be a phase sensor or is there another reason.
