Thanks Adam - I am interested in this because my truck doesn't start up right away, you know in few revs of the starter. The 94 I owned in the past whcih was stock and low miles started right up. In fact it seemed to jump to running state when the ignition was turned on. This 93, which I rebuilt and am going to tear into again seems have to crank alot to get started. So, I was wondering where a leak could be. I didn't get the injectors calibrated last time becuase I don't think I had that info about it. This time that will be par for the course. Having read all of you peoples posts for the past 5 or six years. And of course, it could be another problem, but it sure acts like what Stace was talking about. Sorry I haven't tried the jump yet. Appreciate the response. Don't shoot me but I do have a fsm for the year.
