Hey guys, a few of you know that I've been working on my TC for a while now, and I've finally got it all together and ready to start. :-)

However, I'm out in the driveway trying to start it up and I can't get her to fire. I don't think it's getting fuel and I'm not exactly sure on how to use the Kirban, but I don't think that is the problem. A thought that crossed my mind is if I could have mixed up the fuel supply and return lines on the fuel rail but I don't think I did that either. I'm running out to get some more gas, I'll be back in a bit for another round.

The fuel lines are different sized so you can't mix them up.

The Kirban may need to be adjusted. Have you checked fuel pressure?

Have you checked spark at the distributor?

Are you sure cam and ignition timing are correct?
Was ignition timing set with a timing light, spout out?

I set the cam timing to the best of my ability and I believe it to be accurate.

I think I narrowed it down to the fuel pump, I did the fuel system diagnosis and jumped the test port and the fuel pump isn't running.

My plan with the ignition timing was to get the car started and use a timing light. I set it all up to the #1 cyl like it said in the tech article.

Found the problem with the fuel pump.

I traced back the power for the fuel pump and found that I never connected the connector for the IRCM power. I connected it and everything kicked on. (smacks head)

still wont start though.

thanks pete, I'm gonna play with it some more but my time is running thin, I leave for bootcamp in about 11 days, I wont be around for a few of them and the priority is just to get the thing running so my father can reclaim the garage.

I'll post my findings+some pictures when I get a chance, it came out pretty decent considering the circumstances.

Alright, here's where I stand:

I have spark and fuel going into the cylinders, but I'm thinking it's a timing issue.

I realigned to cam timing and then it actually started to kick over and sputter a little only when I was pushing the gas to the floor, so that leads me to believe that it may be flooded at this point.

I played with the ignition timing a little but it had little to no effect. I got some detonation in one of the cylinders, could this be a result of too much fuel in the chambers from cranking it over?

Is it actually running. Did you actually have to move the cam from where it was? Have you checked ing timing with a gun, even while cranking.

I doubt if too much fuel will cause detonation at cranking or even idle.

If it is flooded real bad you may need a fresh set of plugs.

no, havn't gotten it running yet. I meant it was backfiring, not detonation. A buddy of mine said these symptoms lead him to believe that the crank is either 180* out or the timing is off quite a bit. I know it's not 180 out so I went back to the timing belt game.

It sounded like it wants to start, just not firing.

Pulled the plugs and they were covered in fuel so I left them out for a little while and put new ones in.

I'm thinking that the problem is the cam timing is still out of wack, I can't seem to get it to line up correctly for some reason. I setup everything and when I let the tensioner out either one of the pulleys moves and/or the other half of the belt has little tension on it. Are there any tips/tricks to this? This is becoming the hardest part of the entire project.

The trick is to watch and see which way it jumps when you release the tensioner and how far it jumps. Then you line it up that much out in the other direction so that when you release the tensioner, it pulls it into the exact correct position
