So the night before a trip to WSIR my 1jz decides to sound like a EJ25 and drives like terrible when i start it . I take it to my mechanic and he looks through it and opens up the engine harness and the extension was done terribly. So after re-doing the harness the car starts up and sounds good but feels like its hitting fuel cut around 4k. So I take my ecu to Driftmotion and recap it and take it back and the car doesnt start. I doubt the recapping could cause this but Im just wondering if anyone in socal has a Soarer 1jzgte and would be willing to let me try my ecu on it.
Thanks

 

Are you sure all your coil pack clips aren't broken? This is a common issue on 1st gen 1JZ's.

 

is it a soarer? if so why is the harness hacked?

 

Is the swap JZZ30 or JZA70? Also yeah sounds like coil packs to me.

 

yea ill have to check those. well its a soarer 1jz in a sc300.

 

jzz30 swap
yea ill check those out and let you guys know, thanks

 

What he ^ said...those things, to include the harness are very bridle. Please let us know what it was.

 

When I did my plugs today I forgot to hook up coil pack wire on #5 and it sounded like a subi. Then pluged it in and wow she purred.

 

is your check engine light on? if its not. the ecu is dead.

 

Unless the CEL wasn't wired in!

 

I forgot to metion that after the car was re-wired it started up and sounded normal just cut off at around 4k rpms. So anyone have a 1jzgte out of a soarer that i could test on?

 

does anyone know if recapping an ecu could cause a car to stop cranking over? or is it highly unlikely?

 

i had a 1uzfe ecu recapped for a 92 SC400. the check engine light wouldn't come back on. i suspect the leaky capasitors did its damage before they were replaced.

the car would start sometimes, and sometimes not. well now its super dead.

 

so anyone that could help me out by trying my ecu out? or have a spare ecu?

 

if your dcar was running before the recap and now it isnt that should be your first suspect.

take it back to the place that recapped it and ask them to double check everything----do it with an angry look in your face lol.

One mistake on the recap could cause your car to behave differently or in your case not run at all.

good luck
