Helpp!! 1jz crank no start issue

[surffer227]

I just finished my 1jz swap in my 240, it ran fine for a day or two but now it will only crank and not fire, intermittently it will start and run for about a minute then cut off and just crank again. I have fuel pressure and I have tried a new ignitor but that didn't work. Any ideas??

Check your codes.

I'm not sure if that was wired in, I have to ask

 

[seoul4korea]

Do a search on how to do it, it should be attached to the intake manifold

 

[theGOODWIN2012]

Double check on your coolant temp sensor. Though it was running fine for a few days before, if it happened to come loose that will cause no start. Not that that ever happened to me :biglaugh:

 

[f00g00]

What harness do you have?

 

[surffer227]

Auto harness and auto soarer ecu I'm running a w58, I know the OBD plug is there just gotta see if it's wired in, at work now so I can't -_- would the temp sensor let it start once in a while?

Could be crank sensor.

Non vvti 1jz is obd 1 meaning the obd plug is useless. W pin on the ecu needs to go to the check engine light wire and then jump te1 and e1 in diag box on the intake manifold.

Pulled a plug and there's no spark when cranking

 

[hvyman]

Wont get spark if the ecu doesnt know engine position.

After cps check your ECU

May want to check the exu first.

Found leaking diodes in ecu, getting them fixed now, hopefully this fixes it

 

[hvyman]

It would be capicators. Diodes dont have anything to leak.
