Car Starting, then Dieing immediatly,

[Johncrow]

I went to the gas station today and bought $10 worth of propane. The guy who was filling my cap wasn't the usual guy, and when I was done, The car couldn't start. It would turn over a lot of times and would occasionally catch on a cylinder here and there but for about 10 minuits, I was stranded at the gas station. Eventually, I tucked my balls away out of sight and asked a guy in a Honda Ridgline to give me a boost (trying that long and hard to start it, the battery could probably get some help turing the engine over). It worked after the second try and I left. I got to my friends house to help him put strobes in his civic and when we finished, I was stranded in his driveway.. I kept trying to start the car and again, it would catch every now and then but not starting. I kept giving it 5-10min brakes just in case the engine was flooded but it still would'nt work. Finally, I put it on gas and in three tries and probably about 15 cranks each it started and I drove home. When I got home, I tried it on propane and same deal ( luckly i didn't have to go anywhere this time). Please Help, and can fuel injection flood?
