Hello --- ive been struggling getting my jeep started after an unanticipated year away. it was sitting in mud for the year unfortunately. Looking back, i should have drained my old fuel -- i may have avoided all this trouble.
Upon return, Car started easily and ran great for one month. Then it started running rough a little bit, then it died on the way to work. I towed it home and managed to get it going again with fuel injector cleaner put directly into the engine via the air intake port.
Next day, was letting it run in the driveway for a little, when it died completely... no chance of starting. Checked the fuse box: ok. Checked the fuel pressure/ purge valve on the rail and all that was coming out was air. But -- it was air under pressure: every time i tried to turn it over it build more air up in the fuel system.
My neighbors seem to think its the fuel pump.
- what about the fuel filter?? kinda seems super clogged to me. if i were to change the filter to start, how do i test it without putting the tank back on... just in case it is the pump too??
- how can i tell if my tank is rusty inside? if it is, how do i fix it? new tank?
- could i have avoided all this if i had changed out the old gas upon returning? There was a half tank in there, then when i returned i put in 20 bucks more.... when it broke it was back to half a tank.
any help would be appreciated.... thank you!
