Over the last few days, when I drive less than 5 miles, then shut the Trooper off for a few minutes, it won't restart ('91 2.8 TBI V6). If it sits for more than an hour, it restarts no problem. If I try to restart immediately after shutting it off, no problem.

But...if it sits for 10 minutes to 1/2 hour or so, no start. <img src="/forums/images/graemlins/confused.gif" alt="" /> I had an appointment yesterday a couple miles from work, wound up having to walk back because it wouldn't restart. Got a ride back after work and it started just fine. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

I haven't had time for a lot of trouble shooting yet, I did look at the distributor cap and rotor last night, they were a bit pitted, so cleaned them up (no help). I pulled a couple of the spark plugs, they had no discoloration or deposits.

When I did get it restarted, I noticed the injector pods (TBI, not MPFI) were leaking quite a bit (stream, not spray). Could the problem be vapor lock from the extra gas? Kind of seems to fit with it only happening when the engine is warm...it cranks like crazy, but doesn't even sound like it's trying to 'catch'. I tried removing the gas cap to depressurize the fuel system, but that didn't help either.

I have a replacement set of injectors already (waiting on the gasket set to install), but should I still be looking for other things? Ignition coil?

If it does sound like vapor lock, anybody have any tips to help start a vapor locked TBI engine until I get the injectors replaced?

Thanks,
