    Well, I have been dealing with this issue for over a year now, and I think I may have actually fixed it! I am still a little tentative about it, but considering I haven't been able to start it hot since late June, I think I may have finally tracked it down. Whenever it wouldn't start, I couldn't hear the fuel pump prime, so I was thinking it was the pump (it seemed to do it worse below 1/4 tank). Figured I would take the cheap route first, so I bought a new fuel pump relay from Napa. Cost me $18. Went out after I bought the relay, and it wouldn't start. Swapped the relays (took all of 90 seconds) and it fired right up. Has started every time since.

    I finally found my problem...I rebuilt the TBI and it now runs like a champ! I'm sure all the changed parts don't hurt either! LOL. Thanks for all of your help guys!

    Ok so it runs great but I'm still having trouble with it starting on its own without the help of starter fluid. Can anyone chime in here please. it runs great once I get it going but every time it needs starter fluid to start it up.

    I replaced the fuel pump relay in my Sub early September of last year. It was an easy replacement and cheap too (about $20). I have not had a starting issue since. Good luck with this.

    I've also changed my relay but still having the problem...IDK what to do next.

    I don't have time to read back, but I had problems with mine doing the same thing. I reseated the 4 pin connector on the distributor, and that got it going. Just make sure your connections are good and don't have any corrosion.
