Your checking incorrectly for spark. Hokk a timing light to the cyliunder in question. If the timing light won't flash, your providing enough voltage to the plug for it to fire. You"ll get the gas from that. It sounds like a cracked coil.
I would start by draining the tank and changing the filter. Then refill with good gas and see if it will run. The first few minutes may be rough as the lines will still have the bad gas in them. If it doesn't straighten out in about 5-10 miles of driving then you may have to change the plugs. If it's still running poorly maybe try some injector cleaner. Don't get too carried away with that stuff though, it's actually kind of hard on them.
Sounds like the switch on the clutch pedal needs adjusted. Is the floor mat bunched up under the pedal, I've seen that. It could also be dirty ground connections. There are several. Not only the battery ground but smaller ones also. A bad ground can mean low voltage to the ECM and injectors. Does the start solenoid click. If it does may be bad battery connections on either end. If it doesn't may be bad connections in the small wires to the solenoid. The alternator could be consuming the available connections when the battery is recharged from starting then the ECM and injectors can have enough. Why it would run rough for a while. The first place to look is always the electrical connections. A lot of people have paid for new starters because of bad connections. I had a friend kept buying alternators from his trusted mechanic because somebody had removed the ground wires from his engine to the chassis. (This was before he asked me to look at it. Of course!)
very likely the fuel injectors are damaged, replace them, the fuel pressure regulator and all rubber fuel lines, also pull the gas tank and replace the short rubber hose at the electric fuel pump, I know this is expensive but even a few miles of running would have wrecked havoc on the rubber components, that rubber debris will flow through the fuel system and will plug the injector's, E85 melts it and skin for that matter.
