Message	If I had to guess. I am Flex fuel and running ethanol June-Sept. But once temps get into the 60’s starting it can be a nightmare. Happened this year. I slowly ran the E out of the tank in Sept. waiting for it to get near empty so I could put my 93 pump in. Sure enough cooler temps at night 65 degrees next AM. Exactl same problems. Wen and got pump 93 in a 5 gallon. Put it in. Fired instantly. What you described is exactly what happens to me when temps get cool here in MN. Oct-June I store with pump 93. I talked with my tuner and they can address this issue for me. But doesn’t matter because I put 93 in for colder months and storage. ` 1990 NA 1993 TT
