I brought a e30 bmw with a cosworth engine running 270 bhp about 18 months ago.I wanted more power so removed the engine and rebuilt with all uprated parts.now the fuel pump has no power going to it and the injectors are not firing.
does the front crank pulley have anything to do with the firing of the injectors?

does anyone have a 2wd colour wiring diagram and ecu pin number diagram?

iv also fitted a swedish plenum and had to cut the loom and extend the wires thats why i want to start at the begining and check everything.

iv tried ecu,crank sensor,3 bar map sensor on another car and all worked fine


any info will be a big help thanks
