C20xe won't inject.

[MattBrown]

Hi Guys.

Got an odd one here, a lad has bought a half finished xe nova track car, the wiring isnt the best, but is OK for now.

Its sparking, and no EML, but for some reason wont fire the injectors.

All earths checked

Full fuel pressure

Inhectors all clipped in correctly

ECU has 13v to it

Sparking perfectly.

tested the injectors yet?

[MattBrown]

Yes, got a set out of a car that runs.

Is the fuel pump relay ok? as this could cause the injectors not to pulse?

[MattBrown]

Fuel pump relay is fine.

Always thought they controlled spark and fuel pump? Not saying your wrong, but Im sure they do lol

[comptoncj]

IIRC it tells the ecu to pulse the injectors, well i thought thats how bosch motronic worked AFM working correctly?

[MattBrown]

Hmm, will have another look then.

Something not right with the wiring, but having 20 minutes to look at it wasnt exactly amazing.

Strange how it sparks yet doesnt pulse

Check pump to see if its getting power, if not then relay is fooked

Is the eml light actually wired in?
