No spark or fuel = bad ecu?

Stil nothing

Here is what I've done.

Tested resistance in both cam sensors , and crank senors, all 3 are in spec

Tested volts at those all were right under 5 when key is on

Tested ignitors and coils both good

Jumped signal wire from ecu to ignitor and got spark coming out of coil
Ran new wires from ecu to ignitors just to make sure


Tested continuity in all the core A wires including earths/grounds got info from this>>

For those who care.


34 pin connector
Pin. Tested
12 -ignitor signal Good
13- sta Good
14-nsw. Good

24- IGT Good
25 IGT2 Good
26. Igf2 Good

33. Ground/earth left. Good
34. Ground earth right. Good





22 pin connector. Tested

5 Ne+ crank. Good
6 ne - Good
10 g1 camleft. Good
11 g1- Good
16 g2+ cam right. Good
17 g2- shares g1- Good

22 earth not to motor BAD added new ground now good






16 pin connector. Tested

16 ground. Good





28 pin connector. Tested

9 ecu power. Good
14 constant power. Good
22 +b ecu switched power. Good




So the only thing it can be is the ecu not sending signal to ignitor?

And the only reason left is the ecu is bad?

Because sensors are good and wires from sensors to ecu are good

And wires from ecu to ignitors are good

Guess ill order one and hope for the best

Yeah I thought this day would never come now all the small time consuming things
