View Full Version : 1jz s13 issues

07-14-2013, 11:39 AM
Hey guys I'm new here. I have a s13 coupe that I've had for a few years with a 1jzgte I've been putting in it and I've almost completed the swap. It runs and drives pretty well actually but I'm having a few issues getting it all fine tuned and I know there are a lot of educated people on here so I figured I'd give it a try.

Info on car:
S13 with 1jz
2jz aristo ecu
440cc injectors
Garrett 57 trim top mount turbo
Tail wastegate
Tial bov
Wiring professionally done
Aero motive fpr
Walbro 340lph fuel pump
Boost signal limiter
Aem uego wideband

1)Car is running lean. What are things to look for when lean?
2) car won't start after it has been started once a day? The second time I try to start it, the car coughs and then just cranks and cranks and cranks.

Things I've tried:
1)new fuel pump
2)new coolant temp sensor
3) new coil packs
4) checked my ecu for leaky capacitors, there were none

Come on you gurus please help me figure this out

Hmm. Why the 2jz ecu?
