2012 Ford Focus se crank but no start
 
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.

I was told that now i have to release the air from fuel line and repressurize it. Someone said find the schraider valve and release it there while having someone prime the fuel pump. I dont even know where it is on the vehicle. Can anyone help?

Is it supposed to have a banjo bolt or schrader valve on fuel line?

Should have the bicycle style valve. Turn key on, pump will prime. Push open valve and it will spit out the air. Do this until its all fuel no air. So, on then off, push valve. On then off, push the valve. and so on. It takes a couple seconds for the pump to stop, so wait that long. You can usually hear the pump buzz then stop. Bad fuel can plug up fuel filter, pump, pressure sensor, injectors, almost all the fuel system. I would change the fuel filter, or if you already did, take it out and drain the filter and fill it full with a good injector cleaner, put it back in and try to start it with that. Get all that air out first. Full dose of cleaner with no fuel will clean out the system.

Where exactly is that located and how do I push the valve? right now i was pushing the air out running the pump but before it hits the other pump under the hood. The filter is lifetime and is in the tank. says it doesnt need replacing or cleaning, couldnt get to it even if i wanted to. But you think this will work?

That sounds like a bad idea, -considering your no start & those symptoms. Advance key to On, and then check your fuel system pressure using a scan tool. Looking for ~40 to 45 psi. Separately, you can check fuel system pressure using an external analog gauge, but this requires some special adapters to TEE into the fuel lines.

Nope. I have never heard that advice on these cars. I have replaced my fuel filter twice and fuel injectors once and never needed to "release air". Key to On a few times, crank once or twice extra, and it fires right-up.

No. There are a very-few older Foci that do have a schrader on the fuel rail, but these are very rare. 2000-2003(?) and not many of these have em'. If there are newer Foci with a schrader, this would be new news for me.

It (2012) should not have a schrader valve. Still waiting for news about this valve that should be there BUT is not.

Yeah, good idea. Most car owners forget to replace the fuel filter as part of preventative maintenance. Most-most important after a new fuel pump.

I am fairly dumb when it comes to newer (MK3) Foci, and I did not know the 2012 does not have an external fuel filter. Are you sure about that?

His Focus has direct injection it's more complicated. What was this bad fuel situation? I'm sorry for your job loss sounds like a crappy employer that doesn't understand. If you worked where I work somebody would have picked you up and took you.

Ima make this short. I had bad gas so i tried to burn some out but it didnt go well. So I dropped the tank and drained it. I put it back in and now someone is tell me that i have to release the air in the line before it hits the high pressure pump under the hood. Doing so by turning key to run the fuel pump thats integrated with the tank. I was told that when i have a significant amount of fuel to put the line back in the high pressure fuel pump and unhook the other end of it so fuel runs through it. (Method Ill be trying today). I know it was bad fuel because it was green and brown.
