No Injection Pulse Rb20det

[requiemk]

Hey guys i need a bit of help, im not getting injection pulse.

car has recently been off the road for a few upgrades and now i don't have injection pulse.

i have power 2 both sides of my injection plug (9volts)

i am getting spark

Theres an earth in the engine bay for engine loom and thats correctly earthed.

i have swapped cas for another unit and still same problem but it shouldn't affect it as im getting spark so cas is functionaly correctly :S

I thought the only inputs needed for injection were Crank position and the ecu earth. ecu is getting power as im getting spark.

cheers any ideas much appreciated.
