    please help this POS LT1 wont start!!!!

    I dont know if this is the right thread but my friend blew his motor (its a lt1 in a 1995 camaro) so he bought a motor out of a 1993 vette. so the opti, water pump, intake, fuel rail, oil pan, windage tray, pickup tube, balancer, timing cover,cam, timing gear, and maybe a few other things were diff, I changed everything but the opti back, the car is getting fire to plugs for sure i tested it, its also getting fuel to the rails, but it wont start. it turns over then drags then turns over then drags until the battery goes dead. whats wrong please any input would be great cause im tired of working on this pos!!!!!

    Timing or injectors are not firing, pull the plugs to see if they are soaked in fuel. IF tis trying to fire the times is very likely retarded or advanced to far in realtion to cam or crank position sensor.

    Beyond that I have no ideas, Could even be the opti just took a dump on ya.

    I think that the earlier optis were able to engage two ways. Meaning the firing order could be 180 degrees out. Are you pos you have the firing order for the wires correct? 1 or 2 crossed might keep it from starting.

    ya I think the opti has a cam sensor in it.. right? well, if the opti is not the right one, then maybe the cam sensor is different too? Heck does the Vette opti even have a cam sensor in it? Who knows. I am only good with factory engines not hybrids.
