Well, not even 500 miles and I'm truly pi$$ed at my new 2017 Ural.
I removed the fuel tank again today so I could gain access to the underside to wire in my new Fiamm horns and USB power outlet for my dash to power my iPhone. I've pulled this tank before, so I thought it would go better this time. Nope...
First mega-gripe... Who is the idiot that designed this fuel tank which has absolutely no single low spot from which to drain out ALL of the gas before removing the tank. Also, hasn't Ural ever heard of quick disconnect fittings which shutoff when disconnected? No, not this thing, it pours gas out of every stupid orifice all over the damn place. What a mess. I've ordered a set of screw type fuel clamps so that I can physically shut off every tube from leaking on removal but damn, who would have though this necessary in 2017?
Next, after finally getting everything back on the bike, I put some fuel back into the tank, prime the pump allowing the gas to pump through a temporary fuel line back into my gas can, reconnect the fuel rail connector, and try to start the bike. The bike won't start. I stop, check everything again which looks great, and try again. Nothing, cranks but won't start. It is then that I realize, I don't hear the fuel pump spinning up anymore!
I pull the fuel tank again except this time, I couldn't drain the gas off using the pump because the damn thing isn't working. Gravity doesn't work because there is no single low spot in the tank. Gas goes everywhere as I struggle to remove the tank. Stupidest design I have ever seen... Truly inexcusable.
I check all connections and backbone wiring to make sure I didn't pull something, or whatever. I can find nothing. I check all of the fuses under the side panel. No blown fuses. All of the mini relays I have to presume are working fine. I hear some of them tick "off and on" with the ignition and engine cutoff switch.
I even pull the fuel pump and the connector to make sure it is okay. Everything looks good and I hadn't touched any of this before the problem and I am stumped. I put my voltmeter on the fuel pump connector. I have to use sewing needles clipped in my alligator teeth clamps of my multimeter in order to try and get a reading from the worlds tiniest female connector ever made (the fuel pump connector) and no matter what I do, I can get no voltage reading at all! What in the world?!? It could be me, because as I said, these are some super microscopic tiny holes in this connector but I've read others just like it 100 times using the same technique. I don't know...
I examine everything again, check all fuses again, visually inspect the wiring loom all under the fuel tank to make sure nothing was pinched, pulled, or rubbed apart. Nothing.
No matter what I do, I can find nothing to indicate why this fuel pump is now refusing to spin up at all, nor why there is no power seemingly coming from the ECU to it. There is no MFI lamp lit on the speedometer.
I am dreading trailering my bike all the way down to Heindl to get them to look at it under warranty but unless somebody has a good idea, I'm just stumped and pi$$ed as can be. I've been wrenching engines of every kind and type for over 40 years but this thing has me scratching my head and cussing and spitting.
Anybody have experience like this and has some wisdom? I'd sure appreciate it right now.
I've attached a HIGH RESOLUTION version of the wiring diagram. Maybe somebody sees something I am not.
