Mini Me Problem

[autox 89 dx]

I just put in my SOHC ZC with my Z6 head head in my 91 Si and went to go try to start it up and it won't start.I tried saturday to start it and it cranked over fine now it just clicks. So I tried to bump start it and it started and ran fine but as soon as I let off the gas it dies. I don't know what it could be maybe a vacuum leak? could the starter also be bad , what do you guys think I'm stumped

Well today I went over the car again and I left off the ground for the tranny thats why the starter wasn't working.I fixed the ground and the car started right up I have to get my timing light back from my buddy so I can time it tomorrow.I put a firdanza fly wheel and it revs so much faster can't wait to drive it.
