No injector pulse on 4agze

[Sprintn]

Just hooked up my loom everything seems to be working fine but still wont start, check injector pulse and there doesnt seem to be any, anyone got some help?,

[Skylar]

Well, do you have spark?

Does the CAS work all good? Probed it on an oscilloscope?

[Sprintn]

Yep spark is all good, no idea what an ascilloscope is lol

Have you earthed the ecu loom (brown wires that bolt to intake manifold)? I assume there is a good earth on the engine (ie thick cable from the block or head to the body, and a couple of other smaller ones).

Traced back the injector power feed wires and made sure they are getting 12v on ignition?

Yep the brown wires are earthed, and indeed I do have a thick earth strap from the block to the battery, and another one from the body to the battery... And the injector wires are getting 12v
