I have a 2008 dodge charger sxt 3.5L V6 RWD, went to jack up the car and punctured my gas tank. The hole was as small as a writing pen. After I noticed that I made a mistake I started the car and it ran for about 5 seconds then died out and wouldn't start again. There was just under 1/4 of a tank of gas left. I put a pan under it and just let the rest drain out that side so I could try to temporarily repair it with Permatex's epoxy stick. After I sealed the hole and let the epoxy cure for the recommended 5 hrs.I put 2 gallons back in the tank and it stopped the leak, now it just turns over and wont start. Any suggestions? I'm going to replace the tank as soon as possible but I needed to try this until then so I could get my kids to school and me and my wife to work. This is our only vehicle and the dealership wants about $1000 to put a new tank on

First check for fuel pressure. If you have none, you likely have to fill the tank more. There is usually a small pot inside that the pump sits in. Return fuel keeps it full when the fuel level is near empty. That's to prevent the engine from dying out on corners when the fuel level is low. If that pot is empty, there's no fuel being pumped to the engine, and no return fuel to fill that pot.

Also listen for the hum of the fuel pump to be sure there isn't some other problem. It should run for one second after turning on the ignition switch.

If you sanded the "shiny" off the tank before you patched it, that patch is likely to be permanent. I used Chrysler's gray RTV gasket sealer on my '88 Grand Caravan over 20 years ago after Ma hit a chunk of steel in the road. The hole was three inches by two inches. That lasted until last year when the tank rusted though in other areas.

If you DO replace the tank, get a second opinion from an independent shop. My steel tank cost less than a hundred bucks from eBay, and the job took about an hour with a hoist. One reason I like my rusty, trusty van is parts are cheaper than for newer vehicles, but a thousand dollars seems awfully high.
