Getting Darth started and running has been at the top of my list for the last month, and it’s been postponed by bad weather. Jen was out of town this Saturday and I wanted to take advantage of that—she hates the exhaust fumes—so I got to work as soon as I could. The first issue was fuel. Last weekend I had her running off fuel I poured in the carb but I couldn’t get her running long enough to pull fuel up into the filter. The other issue was that the negative battery cable had given up and was getting hot to the touch almost immediately after cranking, so I swapped in a new one.
I started out yesterday by hooking my electric pump up to the hose right below the filter and verifying that the pickup wasn’t blocked. With that setup I got her idling roughly off the boat tank, having to stay next to the carb to alternately adjust the choke and accelerator. I backed the idle screws out a quarter and then a half turn with no effect, and kept her running for about five minutes before shutting her down. The idle is more of a gallop, which definitely points to fuel issues, and it’s different than when I had her running last year. The good news is that the exhaust is clear—there’s no white or blue smoke.
I pulled the electric fuel pump off and tried running it off the mechanical unit with no luck. Figuring something was wrong with the mechanical unit, I jacked up the front end, crawled underneath, and pulled it off. It was full of fuel, and I couldn’t see any issues with it—no leaks or damage. So I put it back on, tightened up the connections, and figured I’d sit back and have a think.
The easiest and quickest solution is to just buy a new pump (and a couple of filters), but before I fire the parts cannon I want to review what I know and see if there’s anything I’m missing. The way I’m seeing it, the next move is:
- Replace the fuel filter and see if it’ll pull from the tank. If not,
- Put the electric pump on to prime the mechanical pump, and see if that cleans up the idle. if not,
- Replace the mechanical pump and see if that pulls from the tank.
That took the better part of the morning into the afternoon, and by then the wind was picking up. It started as a warm day but got colder as a front moved in, so I did some minor stuff inside the cab and then moved to the garage. I cut a new pattern for the bench seat support out of 20 gauge steel, measured and marked everything out, and trimmed it up. Then I screwed my bender into the floor and carefully aligned things up. 20 gauge steel is much easier to bend than 16 (what was I thinking) and in about an hour I had a new support formed, with the final adjustments to be made when I cut the old piece out of the truck.
While I’ve got the girl up on jack stands, I’m going to spray the area between the clutch and flywheel with some PBblaster to see if I can get the two to separate. If by some chance I can free things up, I can avoid a costly tow and transmission job, which I’d love to be able to do.
