im doing a mpfi swap im all most done but that ***** not working help no check eng.. lights are on so y is it not firing up.

 

lol gonna need more info that that bud. pics of ur wiring would b helpful

 

hey

check the ECU to see if its flashing any codes...if not then...

check to see if you are getting spark to the plugs, if not check the dizzy and the wiring

if you are then check if you are getting fuel in each cylinder, if not check the injector wiring and the resistor box wiring

if you are then check the timing to make sure that it is at TDC

keep me posted, if you have pics or a more thoroughly explanation it would be much easier to help
