The truck was running earlier today, I started it on the auto start, and went outside when it suddenly died. I tried to restart it several times, and the first few times it would fire and immediately die. I was thinking I had seen gas engines do this before, so lets change the fuel filters.
Yes, I cycled it a few times. I didn't count how many but I'm sure it had to be at least 10 times by now.I was thinking the same thing. In fact it has gotten to the point that I heard the pumps? bog down a bit as they built up pressure. Even though the owners manual said nothing about cycling the key. I just thought it made good sense.
As for opening the drain plug, I took it off first before changing the filter, to release any potential pressure. I had fuel leaking out the whole time. Tank has better than 3/4 in it. The plug was the last thing I put back in.
