Cranking but not starting Sorry for the long post. I'm at a standstill:
Currently putting an LS with a 4L60 in my 65 Nova.
Harness is hooked up and my PCM is reprogrammed (VATS disabled etc).
Car is cranking but not starting: sprayed carb cleaner in the intake and got a rumble.
1. Tested my injector wires by using a noid light, they are pulsing.
2. Did a test on my injectors by connecting 12v and a ground to the injector, heard a click.
3. Removed spark plug wire from spark plug and put a spare plug on wires to see if it would fire, yes I'm receiving fire to all except #2.
4. Checked my spark plugs to see if they are wet with gas or smell like gas; NOTHING.
5. Grounds from my PCM are grounded to frame, should they be grounded to engine? Does it matter?

No start I'm with the above, sounds fuel related. If the engine has been setting for a long time the injectors could be clogged. Search "injector cleaning" for some home cleaning ideas.
If you can hear the pump coming on, and still have no pressure, then you're leaking somewhere. If it's an intank pump, which I'm guessing it is, because you'd see an exterior leak, you've probably blown off the hose between the pump and pick up tube in the sender in the tank.

Yeah.. return port is the center one and the feed is the outer port.. logic would see that be opposite.. but we have big dollar engineers to figure out and design these things for us..
