Hey guys I need some help with my EX. When I started it to leave from work last night it was idling kinda funny and felt as if it had an ever so slight miss and the low fuel light came one. I stopped and put $30 which is ~7 gallons in until i get paid tomorrow. After I left the gas station I felt that it had a bit more of a miss, on my way home there is a slight incline which crests about .75mi up and it took forever. There was now power and the whole truck was shaking like a wet dog. When I finally got to the top of the hill I pulled over and was going to just let her idle for a bit thinking I had air in the fuel system. I tried giving her some RPM to blow the air out and when I held it at about 2000 for a bit I noticed the RPM slowly dropping until I let off the throttle, when I did that it sounded like a Big Block Race engine with a wicked nasty lope, then she quit. Luckily I wasnt to far away from my shop so I had my buddy bring his 6.0L out with a tow strap and we pulled it to the shop where it still sits not wanting to start.

I know there is diesel in the tank so I can rule that out. The batteries have been on the charger for the past hour or so and it cranks over real fast. I pulled the fuel filter and check the bowl it was low almost empty from me opening the drain valve on the side of the road to see if that would help, so I topped it up with a touch of ATF. I didnt have diesel or I would have used it. When I go KOEO I can feel the fuel pump click, but It doesnt really sound like its running. And when I pull the filter with KOEO the fuel bowl doesnt fill up.

My question to you guys is what should I try next? I really need my truck as I'm not to fond of driving the Chevelle in the rain, plus without a heater it gets cold lol. Any thoughts, tips, suggestions are greatly appreciated.

Thanks
Andrew

If the fuel bowl isn't filling, you need to see if the fuel pump is working.
You could put 12V directly to it and see if the bowl fills.
If not, you can set it up to have the fuel pump pull fuel directly from a can of diesel.
If that works, then you'll need to drop the tank and find out what happened in there. That's probably my guess, that the pick up is clogged or loose.

My truck stranded me outside of vegas this past weekend, it started with a rough idle then just stalled and would not start. it cranked but would not fire. turned out to be the IPR connector, a cheap wire connector but cost me over $700 to narrow it down to that.
