I didn't want to be one of those guys who joins and it's obvious they only joined because they have a problem they need help with... but... LOL I do have a problem. I actually don't personally own a PWC but have a friend who has 3 that I ride a lot. I also help maintain them as I have worked on cars for the last 20 years or so. I've learned a LOT working on SeaDoos and find that it's a love/hate kind of relationship. The Rotax motors are awesome when kept up... but that's the key. If they're allowed to go unmaintained man they can bite you! So, having fallen into the world of SeaDoos, enjoying and maintaining I figured I would join a site where folks know what they're talking about when it comes to them.
Oh wait... I did post in the introduction section so this isn't my first post afterall! lol
Anyway, here's the issue... it's on a 2005 RXT Supercharged 3 seater.
Last spring I rebuilt the pump so to speak. It sucked a rock and I had to replace impeller and wear ring. Nice job and learned a lot about the propulsion system on these things. Which is COOL by the way! Ran like new all season until in late summer it wouldn't shut off when you pulled the "key". You could kill the motor but it would beep still. It set for a several weeks since it was the end of the season. (Remember these aren't mine.) When I got the chance to get over to look at them I found it was a bad DESS (?) post. So I swapped it with a used one off a parts ski. Now these set, even though I highly encouraged them to work on winterizing them and have the batts removed, all winter. It was a warm winter but still. Well this spring I stepped in and was determined to get the RXT up and running. After putting all the work into the pump last year I wasn't going to see it just sit right? Now the problem...
This thing turns over fine, but does NOT want to start. I pulled the plugs, and of course without fogging last year, they were nasty and corroded so I replaced them. Still not firing. Pulled the plugs put them into the coil boots and checked against a ground to see if they were sparking. I have spark on all three cylinders. So I drained every ounce of gas out of it, including disconnecting the fuel line to the injector rail and running the pump to get the last little bit in the tank, and filled with fresh high octane. Turns over and spits and sputters like it wants to fire, but just won't get going. I can't find ANY reason for this thing not to run and it's driving me nuts. Pulled the codes on the MPEM and all that is there is the cumpass out of range. That's been there for a few years and never affected the performance of the machine that I know of.
This is the only thing I can think of, and really would love your opinion before spending the money. The batteries... this one has the OEM Yuasa in it, but it's 4 years old and like I said was not maintained over the winter like it should have been. It did get a trickle charge on occasion but seems whenever I went over to check them someone had unplugged the extension cord for something else at one time or another. So it got charged but not all winter long. I cycled the battery by taking it out, running a 10amp charge on it for a couple hours, then trickle overnight. Put a load test on it and it passed, but was on the weak side. So I am at the point of thinking I should change the battery. At the best price of $130 I don't want to just throw money at the thing.
My question is does this sound reasonable or is there something maybe I'm missing? I should mention that I did jump the battery to try and have solid power to see if it was the battery or not, but not sure if that really gives a good indication since jumping does not always give full strength going through a weak battery.
There it is. Any help is GREATLY appreciated!!
