Default 2000 Mustang GT won't start - help!

I park my 2000 GT in an unheated storage building for the winter. It's about 40 degrees today and I haven't started it and let it run for about a month, so I went over to do that. The battery had gone dead. TOTALLY dead. I hooked up a charger and let it charge for about 30 minutes then tried to start it. It turns over just fine but won't fire. Never even tries. Checked the fuel pump reset in the trunk, no problem there. I don't know where to look next. Help!

Default 30 Minutes

Your battery is STILL weak after such a short charge.

Your gasoline is old and decrepit (next time Stabil gas treatment's ad shows the guy with the fancy hot rod boat that won't crank, take it to heart), and if the car was parked with anything but a full tank, it probably has condensed several inches of water in the gas now.

Get some Sea Foam and see if it will help, and get that battery fully charged. Top up the fuel with the Sea Foam and premium gas.

Any numbers of sensors may have decided to glue themselves shut (IAC is a favorite in situations like this), and you might need to just warm up the whole car with a portable heater to get it running again.

Check the oil. If its worn out and low, change it, putting in a good grade of synthetic like Mobil 1 (the synthetics are less affected by cold conditions and storage).

If it still won't start, do NOT keep trying over and over until the starter overheats and ruins your day. Get out the workshop manual and start going through all the steps in the troubleshooting guide.

Check that you're getting spark at all the plugs, fuel to the motor, etc, etc.

Pull the OBD II trouble codes, you might have a stored code that will help explain things.

Thank you for the reply. The gas tank was full and had STP fuel stabilizer added when it was parked for the winter. I think it must be a sensor somewhere. I've left the battery charger on low all day and will give it a try again in the morning.

I am having the exact same problem. I tried listening for my fuel pump to kick on when I put the key in the start position and i heard nothing. Also I tried having someone loosen the fuel bleeder vavlve thats on the left fuel rail when I try to turn the engine over and no fuel came out. I then tried putting some engine starter spary in the air intake adn the engine sounded liek it was firing so I am thinking that for me this is a fuel delivery system problem. not really sure what to do now as far as diagnosing the issue further to find the fuel system component that is the problem. Any suggestions on what exactly I should do next would be appreciated. ( I checked the inertia switch in the trunk adn it was pressed down still and fuse 14 in the fuse box was still good (fuel relay switch)).

johns46 can you post how you resolved your problem or what else you have found out to be the cause of the problem?

Check your fuel pump. If its not pumping, you're going nowhere. john46 never got back to us about what happened, but I would think it was contaminated fuel in his case. He MIGHT have also had a dead pump, but we never got that far in the discussion.

If you pull the pump it can be benchtested. It is probably dead. If NOT then you may have a PCM issue or a wiring issue.

I had the same problem with my 04 GT It turned out to be a bad fuel pump. I disconect my battery when I let the car sit for a week or more.

Ok so that was the problem I installed a new fuel pump and had to jump start the car to get it runing.

Now the problem is with gettin the car to start. At first I thought the battery and the alternator were just old and worn out so I replaced them ( took the alternator around town n i guess no shops were able to test that particular type of alternator). However I have still have to jump the car to get it to start. I have tried letting it run for a while and drove it around with the new parts installed and it does not seem to be holding or creating a charge.

If i have it hooked up to a jumper cable it will start up right away but if it is not it will simply take a few seconds for the lights to fully come on and then when I try to start it you just hear clicking.. not sure whats going on here since i just replaced the battery and the alternator and have drove it around so it should be charging the battery itself at least enough to start itsuelf back up again.

Any help anyone can provide would be appreciated!!!!!
