how would we know if we have crank and cam signals? and what is a relearn? car wouldn't start so we hooked the diagnostics reader up and that was the only code. Were clueless as to what it is

What base program did you flash the PCM with? I used the "411" PCM, started with a stock LS1 F-body program, tweaked it for my cubic inches/injector, added in timing across the board, uploaded that program to the PCM, and the car fired up immediately.

you have a nice scanner. at work i have a snap on soltice. but you hit relearn on the scanner and bring the rpm up for 30 sec or something i cant remember 100%( it tells you why your doing it) and it done after that.
and you need a scanner with live data to see if you have singles from the crank and cam. but i couldnt see a car not running just by a crank relearn. i think your not getting a single from one of them or the tune

you need the crank and cam single to get a injector pulse and coil pulse. if you dont have them the car will not fire
on my 24x swap i had to get the lower timming sprocket thayed down to get a crank single. i called efi and they said aftermarket cranks are all diffrent and to make sure the wheel is right in the middle of the sensor hole
take the crank sensor out and see it the wheel it dead on in the middle of the sensor hole if not your probley not getting the single

I bought the computer with a tune from pcmforless. The coils were from an LTCC setup i bought from someone and they were labeled what cylinder each was for. You think we have the coils switched up and thats the timing issue?

hook a timming gun up on the spark plug wires and that will tell you if you have spark ( it might be on the wrong cylinder but you will know) and you have to follow the wires in the coil harness to see which one goes where. i rewired mine so i know mine were right. a
nd did you switch the firing order in the harness or ecu. you can do it eather way i did mine in the harness.

left the coil harness the same from the LTCC setup we didn't change anything as far as firing order. Just plugged the ltcc harness into the new wiring and then plugged them in the order he had it. guess we'll see with a timing gun

yes. i can have the wiring up for you tomorrow. u need to switch 4 cylinders around i beleive. or it might be 3 ( injectors and coils)
but take the ls firing order and put it on the lt cylinders does this make sense

our harness was the plug and play and the injector connections only reached to certain injectors and was labeled. so shouldnt it just be in the firing order?
