Run then quit?? Anyone else had this?

My stang was just gone through and new gaskets were put in and a new tranny too. I got it all hooked up and it will start for a little bit and idle kind of high for about 15 seconds and then die. It had a nw coil put on and plugs. Im kind of thinking its gas related. This happen to anyone else?? What fixed it??

No info about your car's model year, EFI or carb, no mods listed. Makes it hard to troubleshoot when we don't know what you have. It could even be a chevvy for all we know...

That's why it is a good idea to use the sig under the user control panel (User CP) option. It allows you to post your car year & mods, which help greatly when troubleshooting things. No, it is not there for us to snoop and see any "Secrets" you have hidden away under the hood. Be a good stangnetter and update you sig for future reference & don't keep us guessing.

the motor was gone through and all new gaskets were put in. it was cleaned up a bit and a E303 cam was put in. nothing out of the ordinary.

Either you really don't get it or aren't interested in getting help.

The model year of the car is needed. The electrical wiring and the fuel system changed several times between 79 and 95.

There is no clue as to what engine you are running. Is it a stock block 302, 302 based stroker, 351 or 351 based stroker?

Is the engine running carb or EFI?

If your car is EFI, is it mass air or speed density?

If your car is EFI , does it have the stock fuel system, or does it have a larger fuel pump and/or adjustable fuel pressure regulator?

its completely stock 5.0? stock everything with the A3M computer(mass air). Nothing except the cam. Everything else is stock.
