I can't figure this one out.

1jz auto swap into stock 5 speed w58 sc300.

Got everything in exteneded all the body plugs. Crank perfectly fine. Timing is fine.

I got no spark and no fuel at the injectors. There is fuel in the rail.

I checked the crank and cam sensors all have voltage.

Ignitor is getting voltage. Only thing I can think of is the ECU, but before I go and buy another ECU anyone have any suggestion what might be the problem?

Could the speed sensor not being wired correctly cause this? Is there any wire that was needed to be swaped on the ecu or body plugs for it to fire the spark plugs/injectors?

have you checked your neutral saftey switch or did you bypass it?

Off topic, but if you had a 5spd SC, why'd you go auto 1J? Or do you just mean the engine was auto but you kept it 5spd? lol

1jz auto swap with w58 stock tranny.

I already did bypass the NSS and it crank perfectly fine. I just have no
spark and injectors spraying.

when i did my 1j swap i had the same thing, i found a big fat brown wire that was the power supply for the injectors, it was not hooked to power, ohm test between an injector connector, and your bodyplugs to find which one it is, it might be hiding somewhere.
*side note* the ecm supplies the ground for the injectors make sure you are not checking those wires.

Was it a brown wire that needed to be excited? If so I know exactly where that is.

Check the Crank angle sensor on the oil pump if its connected and the temp sensor on the upper water neck. The 2 wire sensor is for the ECU and the single wire sensor is for the gauge cluster.

I just swaped the crank sensor with another. both sensor on the upper water neck looks fine. After I changed the crank sensor, seems like I'm getting fuel now. No spark still. I'm going to add more grounds to see if it'll help.

Spark plug is gapped at .0.27 correct?

yes, the large fat wire needs to have 12v connected to it, make sure that wire is the wire going to the injectors though... the ecm provides the ground as i said before but the large brown wire in the harness needs 12v ign power, how are your sure you are not getting spark? can you visually see that you aren't getting spark?

dinhnerz

Yeah I can't see any spark when I grounded the spark plugs. I even tried different spark plugs and different coil. I can smell the fuel on the plugs now.

could be the ignitor taking a dump, assuming you got one with your engine set

dinhnerz

Anyone know how to test the igniter?

dinhnerz

Looks like I'm not getting voltage at the ECU at the ign wire when the key is at the 2nd on. Anyone know if there is suppose to be voltage there?

dinhnerz

Turn out igniter is fine. Seem like wiring problems. Anyone know when you're extending the body plugs, there was a big brown wire what exactly was that one for? Anyone know?

dinhnerz

I'm not getting voltage to the wires circled in red. I'm suppose to be getting constant voltage to that. Anyone know why is that?
