93 with no start problem - ZR-1 Net Registry Forums

Hello Gang,

I've got a no start problem and I'm looking to see if anyone has any quick suggestion or common causes before I jump into the diagnostic charts in the FSM.

Here is the history....

My last big road trip down to Montana I was experiencing hard starting when the car was hot and driven for a lengthy period. Then on the second day, the car sudden stalled out and would not start, only turn over. I popped the hood, did some minor touching of connectors etc. After 10 minutes, the car started and ran fine. On the third day, waiting at the border crossing, the car has a hell of a time starting after shutting it off to talk with border services (at this point I'm thinking my new fuel regulator is giving me troubles).

Travel 4.5 hours at various speeds with no troubles. I pull into a small town for a soda and bam no start. Pushed it to a friend's house and played around with it. Popped the fuel lines, had pressure etc. Continued to play with it and finally after 45 minutes it started. I got it home (well almost) and then it quit again. It?s been in the garage since then and it won't start no matter what.

There is no CEL.

Due to a busy work schedule, I haven't had much time to thoroughly dig into it. I have check the basics and found that I have no spark. I've checked the connectors by the coils etc, all look good.

The plan is to get into over the next few evenings and hopefully figure out the cause. I know the crankshaft sensors suck in GM?s, so I was leaning towards maybe doing that.

Any suggestions would be greatly appreciated!!

PS - I tried running a search for similar topics, but some of the words are too small or too common, so they don't bring back any results. For example "no start"

Thanks again

Tyler
