Went out to pump water and work on problem section of my driveway. My 3" pump that always starts in 2 or 3 pulls at the most wouldn't start today. It was killing my back pulling it so I just left it. It had been outside in the rain so maybe something got wet.
I needed to bring about 20 or so yards of clay to the bad spot of my driveway. I figured it would be the best if I could use the dump truck but it hasn't been running for about a year. I was skeptical I could get it going. I used my truck to boost 1 battery and hooked a battery charger on the other 2 batteries. At first the battery charger showed an error and didn't register anything. I put it on my pick up battery and it showed 100% charge. After that it worked on the dump truck batteries. Truck wouldn't even click at first but the air buzzer was loud and clear. I worked on driveway for a little less than hour and came back to see if the batteries had any charge. To my amazement the truck spun over fast and started right up. I gave it some more revs. but it died 30 seconds later but that's normal with the M11 in the truck. Sometimes it will catch and keep running before losing prime. I thought about taking the fuel filter off and filling it but was really surprised it spun so fast. It usually has to crank for about 20 seconds to prime itself after the initial start so I was worried the batteries wouldn't have enough juice for a 2nd start. I hit the starter button just to see and it started in about 10 seconds so must have been close to filling the filter back up. It stays running after the 2nd start and can be shut off and started all day as long as long as it's not sitting for over about 4 hours. I was really glad I got it going and didn't even need to open the hood.
The last time I started it last year was kind of a pain. Some guys helping me went to start it without knowing the drill. I don't use the truck real often so when I go to start it I always boost it and/or put a battery charger on it so it spins at max. cranking speed and will start a second time when it loses prime. They just tried to start it with it cranking slow. We didn't need the truck that day anyway. When I did need the truck a couple weeks later it was a pain to get going. I took the filter off and filled it but it didn't seem to be picking up fuel. I thought the fuel pump was shot or worse. After about four 10 second tries it finally started. It always starts instantly if it was shut off after use and the batteries are fully charged for the next start. I think when the other guys tried to start it all it did was completely empty the filter and maybe some other fuel lines. That's why I was so glad it started right up today. I'm not sure why it loses prime. The check valve was good and I bought a filter that's supposed to help but still quits after 30 seconds. I've read that braided fuel lines can leak air but show no sign of a fuel leak. Also read maybe the fuel tanks need to be filled more but that's pretty costly when I don't use the truck much.
