urgant help needed with ABY not starter

[flat out 90]

Even with the ecu unplugged I’m still getting the injectors open.

[flat out 90]

Is there a relay for the ecu other then the fuel pump one.

[jp_paul]

There is a relay that makes the X rail live, but I don't think the ECU is fed off the X rail as that goes dead on cranking. I had issues with it on an old 90 I ended up just shorting it out

[flat out 90]

Ok it’s just nothing is making sense at all. It’s like the injectors are open all the time that’s what really doesn’t make sense

[jp_paul]

So dumping loads of fuel into the cylinders all the time, on ignition switch in position 2 and 3 (cranking)?

[flat out 90]

Possible but that’s a new has before I wasn’t getting any fuel or spark but still not getting a spark

[jp_paul]

Don't forget the ecu switches the injector earth...

[flat out 90]

May be I’m doing it wrong but with the ecu unplugged there is still 12vs on both sides of the injector plug

[flat out 90]

I will say though things are getting hot like the ecu Is getting hot when the ignition is turned on. Not red hot but hotter than what I think it should be

[jp_paul]

Yes, that's what I mean. The ECU switches the injectors earth circuit, not feed

[flat out 90]

Ok well I’ll just double check that but if that’s ok I’m back to square one

[jp_paul]

Did you check the distributor hall sender?

[flat out 90]

Yes all wires checked and hall sender replaced. From a known working one. When I do the led test it shows it’s working fine.

[jp_paul]

I'm feeling your pain

That’s normal. The injector won’t open till the ECU grounds one side.
