i rebuilt my LS motor (sleeved, bigger pistons, stronger rods etc.) i installed the engine and only two cylinders are working. what could be the problem?

 

Inverted a pair of spark plug wires?

 

already checked that...
maybe this would help...

when i sprayed brake fluid up the intake it runs fine ..so im thinking its not getting any fuel.

does the vafc have anything to do with the problem...any settings i need to put it on?

 

You have to set the type to 4 CYL and the TPS voltage input as rising upward.

 

could me not hookin up the intercooler piping be a problem because im missing alittle piece of pipe so that part is just open right now...just a little note.

 

No, that would only matter in cars with a MAF sensor. Those cars would sputter and die. Your car possesses none, therefore if the turbo piping ever blew, you'd just run like an NA car.


Make sure your spark plug wires are firing, your timing is on, and that your injectors and fuel pump are working.

 

okay the spark plugs are firing....
the timing is good....
the injectors are good cause i flip flopped it with the the 1,4, and still one and four is not working...
the fuel pump...haven't checked that yet but, if the 2,3 cyclinders are good, then that means that the pump should be good right?
