Default car wont start

I ran my car pretty low on fuel. Drove to the gas station, turned the car off while i went to help someone with a seperate issue and when i went to start the car back up, all it did was crank very fast. I figured i ran the car out of gas. I didnt think the fuel was that low but i guess i'm just a moron. pushed the car ten feet ahead and put gas in. No start. Just a lot of fast cranking. Push the car to my house, three blocks away, pop the schrader valve under the driver side frc and i've got fuel coming in a solid stream. The car will still not start. Popped the negative off the battery (praying for a simple solution) and still no start. Fuel system is pressurized. anyone have any ideas before i have to bend over in front of the dealer? The car is an 05 m6 with 23k and no cel's

Not that it should matter but, did you fill it up when you added fuel back in? A thorughly full tank might help send a little more pressure to the fuel pump(s) maybe?
I was going to suggest the battery thing but you already did that part.
I would say let it sit a while longer and just keep trying, but don't try too many times in a row or it could kill the starter.

Sometimes running a car out of gas will ruin the fuel pump because it overheats. Do you have a gauge that you can put on your fuel rail to see if you are getting good pressure?

I'm going to get a gauge later today. Things got more weird. I let the car sit overnight, as i was running out for work yesterday morning, i figured why not give it a shot. Car fires right up. Take it for a ride after work about 15 miles total and it runs great. bring it back home and park it. i go to take it out later last night and nothing. just cranks. let it sit over night until this morning, and again, nothing.

Default my vote

is for a loose electrical connection in the ignition system.

Check these and maybe get some dielectric grease for the connections as you check them.

Good luck

well things took a turn for the worse today. no fuel is getting to the rails now. fuel pump fuse and relay are good. Looks like the inevitable will have to happen. I changed a fuel pump on a 2000 c5, looks as though the design has been changed since lol. Exhaust, suspension and even the rear looks like it has to be dropped, sigh. I searched to see if there were any instructions on this but i havent had any luck finding them. I dont have a shop manual either.

Bad luck.

This is worse than the guy who took steel wool to his windshield trying to clean it.

If it is the fp that needs to be replaced, I was told almost a year ago by a chev tech that it is quite involved. Not that you can't do it, but supposedly the shop manual calls for a lot of labor (about 7 hours worth). Good luck. If it were me, I'd find a good indy shop to do it vs. the dealer who probably still hasn't done one yet.

Not to get off the beaten path here, but I believe this may be a warranty issue.

If the car is still in warranty, or has a GMPP, it might be eligible for repair under warranty.

I've done it recently. It's not a fun job. The hardest part is getting access to the tanks. You have to drop the entire rear section, exhaust, flexplate, etc. Other than that the crossover tube is the worst. I have lots of pics of whatever you will need.

If you have any questions, feel free to PM me. Here is the Left Tank Removal from the service manual.

This is what the tanks look like. The early 05's had a fuel sending unit problem that required many left tanks to be removed including mine. The dealer techs got good at it and learned how to do it with out removing the entire rear section. The mn6 is easier than the Auto trans. Mine took the dealer around four hours.

I take my statement back about the dealers not doing any yet... Thanks for the info, Les!

If it was a crank sensor then i'd still be getting fuel to my rails, just no injectors firing. I have NO fuel pressure at the rail

The unit is in the tank so it's labor intensive.If you're out of warranty maybe a local mechanic you trust and who's familiar w/this setup might save you some cash.Hell,maybe somebody on here can guide you thru the process!

heh, i ended up killing the battery last night, i was closing things up tonight and noticed fuel at the shrader valve.. jump start the car and ity fires right up. I left it run for 20 minutes. gave it a few revs. Shut it down and turned it back on a couple times and it everything worked fine. I still dont trust it and i will wait until i get a fuel pressure gauge before i try to go anywhere... this sucks because carlisle is coming up and i was really hoping to at least get a t stat and tune
