Car Stall problems of the 2014 Ford Transit Connect

After having several flat tires I had to drive off the interstate after the right front tire went flat and the engine must have bounced up and down too much so the accident dashboard light came on. The fuel injection system was affected as well and the car didn't want to start, started misfiring and conked out at low speeds. Whenever I put fuel in to the gas tank the car didn't want to start again and sometimes I had to turn the key 10>20 times to start the engine. Unless when I put fuel into the tank and I kept the engine running (fire hazard). After several thousand miles of driving the car after the car accident light came on and no repairs done to the car the misfiring and stalling out at low speed would dissipate except for the refueling problem. Or at least until the car went over a large bump/pothole and then start all over again stalling out at low speeds. I did take the car to a goodyear auto repair shop and they told me it may take 2>3 days worth of repairs to fix it. Unfortunately I still do not have the money to fix it and probably can't afford to fix it multiple times as the expense would amount to two>. Three times the current value of the car itself plus the problems with the engine bouncing too much just causes the same problem to reoccur so it's basically a bottomless pit of repair and expense.

"engine fault, service now" light comes on upon ignition, and while operating. Engine bucks, stalls, and slips. This has happened more than 100 times since I purchased the van in August 2014. The dealership says they do not know how to fix it. It is a known problem with Ford, but they are completely ignoring me. My cust. Service rep tells me that the "next step" is to take it to the dealership to have them repair it. The van is unrepairable and dangerous.
