well i have just built up my 4x4 to 2wd !! 2wd engine ,2wdecu,2wd wiring loom, all set to go and i have no spark when turning the car over have changed all these parts still same problem !! cps,ecu,chip,coil,dizzy,rotor,ign amp,loom,phase, relays, running out of ideas here i get a spark when turned to pos 2 and nothing when cranking !! fuel pump primes and have fuel pressure just no spark !! all 4 lugs are there on the pulley and checked power at coil and sensors and have changed the factory alarm relay box and have no aftermarket alarm on the car !! anyone ideas before i give up :P and timing is spot on too

 

When you say "my 4x4 to 2wd new motor" what do you mean, a 4x4 engine in a 2wd? What engine and sensors, and what loom?

 

i put in a 2wd engine m8 with 2wd loom and l6 ecu

 

wire going to the phase sensor's wrong way at a guess

 

nope mate they are round the right way

 

A quick pot shot, do you have the correct TPS for L6

 

TPS won't prevent a spark though, my money is on the ECU/chip or bad CPS.
