Boosted Ls1 240sx (Not starting) Hi guys, Trying to get this ls1 started, In the scanner under as far as codes go it gets crankshaft re-learn, now Ive seached and searched and found that its in bi-di controls but hw do you get to those settings, here's my setup:
-ls1 shortblock (camaro)
- 317 heads w/ comp 918's
- MLS and arp head studs
- aftermarket fuel rails
- 120lbs injectors (lucas)
- aem injector driver
- 76mm turbo
- tial mvs
- ati dampner pulley
- 2004 GTO 5.7l pcm
- ls1 corvette harnes pinned to gto.
- camaro TB
- th350 Built by JW.
The car cranks but no turn on, Im by myself so I cant check for spark, fuels there but dont know if injectors are firing.
Heres my tune I have hp tuners pro w/ mpvi controller and 3bar map sensor.
Any help would be greatly appriciated. Also I have found my flow rate calculator, so I still havent put that in yet.

You can't do a re-learn without a BCM, and I have never seen one in a swap. At any rate, it has no bearing on whether or not a car will start.
Unless that's an e85 car, that seems like about 2x the needed fuel injector. That combined with a 3bar MAP with no bottom end resolution.... well, good luck with the whole clean idle thing.
Don't spend too much time cranking on this thing in a no-start condition with those monster injectors, you will wash those cylinders out.

Do you have VATS disabled? or a VATS bypass installed? Start with the simple/obvious things that can keep a car from starting. I'm in Baltimore also, if you need some help checking over things I may be able to help you. I just helped another member complete his RX7 LS1 swap where I wired it completely from scratch. PM me if you want some local help.

Spend a few minutes to wire in a push button switch to the starter. It's a handy tool for exactly what U R looking to do....
I get them @NAPA, with a water proof cover..Not much $$.
