I have a 2012 Ford Focus se. I had bad gas but I’ve dropped the tank and put it back in already. New spark plugs were added but I still have the same problem as when I found out about the bad gas. It will only start with starting fluid and when it does the rpm revs up the shuts back down. If it doesn’t do that then it goes to .5rpm and just jumps till it dies back down. I have good gas in there now and still same problem. I don’t have a factory warranty and my power train warranty doesn’t cover any repairs. Check engine light cuts on then back off from time to time. No codes are read and the transmission light is on. If anyone can help this would be greatly appreciated. I’m believing fuel injectors are next to replace but I’m hoping they aren’t the problem as I just lost my job due this problem. I can hear the fuel pump going but it is quieter than before I took the tank out. I’m running out of options. I don’t have money for a tow truck to take it to a shop. Even if I did I wouldn’t be able to pay them neither. I got it 2 months ago and it had 42k miles. I do a lot of driving so now it has 47k miles but the low amount of miles makes me believe there is something bigger that is a problem.
