Ford Repair: mustang wont start, electronic fuel injection, mustang gt


Question
Steve, in response to your response, thanks ,I have a feeling it has something to do wtih the fuel. She filled up the car a few weeks ago adn that was the first time since I left a year ago I believe. possibly turning up all that gunk and sediment. Hopefully this will be something since she drove it about three weeks ago. But did leave it sitting around too much. It would be a shame to come back from a year overseas to a broken down vehicle. If it is a fuel system issue and needs to be cleaned out about how long/how much would that take/cost?

hi, I have a 2002 mustang GT, I had it for one year and then was deployed for a year overseas, i am set to return in one week and I left my car at my folks house. It sat there for the past year, and my folks started it from time to time and took it out once in awhile. It probably didn't get out as much as I wanted but did not sit the entire time. Apparently now it will not start. It turns over, tries to start, sometimes starts but will not idle. All fluids are fine, nothing appears broken or falling apart it just won't start. Do you have any idea of what this could be indicative of? Is it just a gummed up carb from sitting too long or could it be worse on such a relatively new car?

  Actually, your car has electronic fuel injection, no carb.  There's a few possible problems here...the biggest being the gas.  If gas hasn't been refilled much or at all then it could very easily be bad...gas will eventually breakdown if left for too long and thicken up.  If this is the case you'll have to have the tank dropped and most likely have to have the fuel system cleaned.  A side effect of this is possible gummed up injectors.  Your plugs could also be fouled.  They need to be warmed up every so often (at least once a month and run for about 20-30 minutes).  If both of those issues check out ok, then it's time to head to a shop and see if they can't pull any codes.  There's a lot of problems that can occur from a car not being used so it's important to have professionals check it out.  Hope this helps.

  Honestly, it totally depends on the shop and exactly what they plan on doing.  It should never take more than a day (between dropping your car off and picking it up).  It will take longer if they actually disassemble the lines and clean them thoroughly, but still within a day.  Many places will simply drop the tank, drain it, and flush some system cleaner through there.  This will usually do the trick.  Just keep your fingers crossed that the injectors aren't gunked up as well.  Hope this helps.
