Hey guys, First off, Happy 4th!! okay so the other i was driving her and she was running like a champ. I shut her off for about 15 minutes came back and all of sudden she acted like she was out of gas. spitting and sputtering for about 3 minutes then ended with a very very loud backfire. and i havent got her to start since! the car was low on gas but not empty! i thinking a fuel filter but what yall think? she is a 81 911sc 3.0 fuel injected


please email me directly warrent22@gmail.com

Thanks

Check valve in the fuel pump neck and you may have toasted the air box.

Get some CIS fuel gauges......

Do you have a pop off valve in the airbox?...airbox is the big thingy on top of engine. The pop off may have popped and that will not allow the car to start. If it has popped...reseat it and try to start the car. Good luck !

Remove air filter from under black cover and look for toilet bowl lid, make sure lid is securely closed!
