i'm new to the forum and by mistake i posted this question in the wrong area. hope someone finds it this time...

ok. i have a strange problem but i know it is related to fuel. i have a 2.8 that runs great once its started. idles great, drives great, great power, etc. it will start up with no problem if it has been sitting for a day or several hours. however, if i drive it, turn it off, and then try to start it in less than 30-60 minutes i can't get it started. i thought this was because the engine was getting flooded from leaky injector but it doesn't look like the case. i pulled off the air cleaner and ran the engine for 30 minutes then tried to start it after 10 minutes off. sure enough it wouldn't start. so then i sprayed starting fluid and it started right up. so what in the heck is happening to my fuel delivery for starting after the engine is warm? doesn't make any sense to me. it runs great after its started but doesn't want to start up with in 30 minutes of the engine running HELP!!!

Yours is not a typical problem. It is possible that the ICM is malfunctioning a bit when getting warm. Usually the spark goes, but it's possible that only the injector signal is bad.

Maybe, Cold start injector? Have you checked the fuel pressure? How is the rest of
your ignition components?

Advice from the General Chat Forum is that your fuel pump is bad. You can go after that first, or do some other trouble shooting to confirm.

Do you have some photos of your fuel line routing? Are your heat shields in place? It may be vapor lock - the fuel boils in the line. Today's fuels boil at a lower temperature due to the addition of ethanol.
