5M-GEy injectors

after going over the entire ignition system and finding no reason to my engine not running, had a look at fuel system.
seems the injectors werent working, they arent getting any power from the injector plugs.
ive gone over a hell of a lot of wireing but still cant figure out why the injectors wont pulse.
they have + power but wont earth out when i crank the engine.
thanks, jesse

have you checked the terminal on the ecu?
could be an internal ecu isssue (ie. its rooted)

i checked the earths to the ecu and stuff but wasnt sure what else to check.
do i check the 2 injector plugs for earth?

being earth switched it cant be anything else but the ecu if they are getting 12v.
check the wires for continuity
have you checked the resistor?

we checked the resistor for + power and it was alright.
sounds like it might be the ecu some how, strange though because ive had the car running on that ecu only days ago.

Make sure you have a really good, solid earth for the injectors (pins E01 and E02 on the ECU from memory), these should be thick chunky wires and they should earth on the inlet manifold near the injectors.
If it's not that, your ECU isn't pulsing the injectors for some reason... and there could be a hundred different reasons why.
