I am now getting a fuel pressure reading on my gauge. Still no injector activity. In the haltech tuner when cranking I see no injector duty cycle or anything.
**UPDATE**
MJ, bumped the injectors with 12v and heard them click.
I got it running, I have fuel flow. The harness for the CKP sensor on the front of the block was pulled out about 1/4 inch. I just started following wires to all the sensors and noticed it. Now that I know it will work its way out I need to get a new clip for it. Anyone making a junkyard run?
Thanks for all the help. I think that there were actually two problems that's why this was a little confusing.
Problem #1: MAP sensor wiring was poorly crimped and loose. Vacuum line running to Aeromotive pressure regulator was cracked. After fixing these problems I started seeing fuel pressure.
Problem #2: CKP sensor harness is missing the clip, worked it's way loose. After fixing this the car fired up.

If you're talking about the little cheesy metal clip that holds the connector in place, then I'd recommend just using some wire and twisting it to lock it on. I hate those stupid things. They always fly off when I work on my car, and it just pisses me off because now I have to go hunt it down. 02.gif

Use a strong paperclip and form a new clip with it, it'll work just as good. I can get you one soon if you want, but let me check the garage first.
