rpsinc Posted January 17, 2020 Report Share Posted January 17, 2020 I have a 2001 4700LP with DT530. It has been progressively harder to start it. Seems to me to be the fuel system bleeding down. I am not sure what to do to prevent it other than starting it every week, and I really dont want to do that. Is there something else I can try? I keep covers on tires and solar panel on batteries. Life is making it impossible to use regularly but I dont want it to deteriorate more than it has to. Have a potential time frame to get it out but need to solve this issue. Any input from experienced usesrs/owners?? Quote Marcel Link to comment Share on other sites More sharing options...
Darryl&Rita Posted January 17, 2020 Report Share Posted January 17, 2020 Description of issues? Does it spin over at the same speed? Does starter speed change during cranking? When was the last time the oil was changed? Oil level checked?

rpsinc Posted January 17, 2020 Author Report Share Posted January 17, 2020 Starter seems to be a bit lazy but I think it may have to do with 5+YO batteries, but have tried starting it with charger on 50A. Not sure but thinking that starter not spinning engine fast enough which is why the charger on 50A. Oil changed 2000 miles ago and level is good.

Darryl&Rita Posted January 17, 2020 Report Share Posted January 17, 2020 (edited) You definitely need full cranking speed to fire. It should spin over at 150 RPM, minimum. Get that corrected, first. ETA: With a 50 amp boost helping the batteries, it's time to look at the wires and connections, as well as the batteries.

rpsinc Posted January 18, 2020 Author Report Share Posted January 18, 2020 Had time today to do some troubleshooting and discovered batteries were 7+ years old. So replacing them now. Will also check fuel filter for fuel inside. Did not have a wrench large enough for the one on the DT530. So picked one up with new batteries.

rpsinc Posted January 18, 2020 Author Report Share Posted January 18, 2020 Your advice was spot on. Changed the batteries and voila!! It started in just a few seconds. Guess I dont have a fuel delivery problem. Now to schedule a trip. Havent been out since National HDT Rally of 2018. This working thing is getting old.
