1989 325i motronic 1.3 spark, fuel pressure but still not go

[Varden]

hi everyone,

i recently installed a 325i engine and motronic 1.3 efi into my e21 323i, but despite it having spark to the plugs and fuel to the regulator while the car cranks over it just won't start, i think its the tps i can hear clicking on and off when i turn on the ign and the solenoid on the manifold buzzes too but no go.

Apart from my cocking up the wiring job are there any other pitfalls to look out for?

Motronic engine plug differences that could stuff up wiring plans?

It was a 325i 4dr auto i pulled the engine out of, and it was running before i wrecked it out.



Any tips and pointers greatly appreciated.

What the hey more pics...

Not sure if it has any bearing Varden, but did you change the Crank Position Sensor?
