I'm at a loss! ![Frown](https://dodgeforum.com/forum/images/smilies/frown.gif)
I just got my used 1999 Neon about a month ago. Took it to the mechanic, no problems whatsoever, has been running like a champ.
Drove it home this morning just fine, no issues, and three hours later when I went to start it, it won't catch. The engine cranks but won't start.
The battery's fine, we tested it and tried to jump it. Tested all the relays in the engine fuse block along with the fuel pump and ignition fuses, and they're all fine.
For whatever reason, it just won't start. There's no smell of gas so I don't think it's flooding, but I'll pull a spark plug tommorrow just to be sure and see if fuel injects into the cylinder.
Is there anything else electrical it could be? It seems the fuel pump just isn't pumping. Maybe a fuse inside the car or do the neons have a kill switch if they get bumped too hard? We live in a neighborhood with alot of kids.
If anyone has had this issue that can give me other things to try, I'd greatly appreciate it!

Not Nssicarily...I've had this problem before...Under the hood in the relay box, there is a relay for the Auto Shut Down...You are going to want to try and jump that relay...pin 87 (not 87a-the middle pin) to pin 85...the fuel pump should turn on...if it doesn't, then you got a bad fuel pump or you are out of gas.

Doh! I'm an idiot. I was checking the fuses in the engine block, not the ones under the dash. The fuel pump relay fuse in the dash is grounded and blows instantly, went through 6 fuses as soon as it starts up.
The mechanic spent a few hours checking it out and hopefully it's just a short, but that involves checking the different wires in the harness, an expensive procedure.
Looks like my car is stuck at the shop until I get paid again
