Suck, Squeeze, Bang, Blow

Long-time lurker, first-time post.

On mile 349 of a 350-mile loop last week, my '06 RG died! I went to leave a stop sign, and it quit. I can't restart it. Here are the DTC results:

P none PN 141nr004-0 (I can't find any such PN)
S none PN 68920-01d (I think this is a turn signal cancel module)
SP none PN 67261-04 (this is the actual PN for the speedometer)
T none PN 67459-04 (this is the actual PN for the tachometer)

So, I don't have any DTCs to help me troubleshoot this issue. I'm getting back to the simple four-stroke cycle of suck, squeeze, bang, blow.

My air filter is super dirty (I'm the third owner and have ridden it about 2,000 miles). I'd guess it has been YEARS since the air filter was changed out, but I don't think SUCK is the issue, because I tried to start the bike without the air filter and got no love.

As for SQUEEZE, the engine is turning over via the starter, and I doubt I all the sudden lost compression on both cylinders. I'm moving past this as an issue for now.

BANG! I pulled the spark plugs and am getting spark to each one. That said, I don't know if they're sparking when they should from a timing standpoint. And, Mr. BANG also requires fuel. I can't tell if I'm getting fuel, but I've half a tank of the bang juice.

When it comes to BLOW, no one ran up and stuffed bananas in my Rhineharts at the stop sign, so, like SQUEEZE, I'm going to assume BLOW is working fine.

Tomorrow I'll have a fresh air filter on the bike (dealership sold me the incorrect one today), but, as stated above, I don't think SUCK is the issue.

So, I'm down to fuel and electrical. I'll apologize now for this being my first FI bike to troubleshoot - carbs seem simpler when $HIT hits the fan! What's the process to see if I'm getting fuel delivered? Open the butterfly and look for flying fuel?

Also, I've searched various forums here, but I can't find procedures for troubleshooting electrical components. I have a multimeter, and I'm not afraid to use it! But, as a for instance, my service manual does not give me any insight into determining if a component is within spec. It's simply, "do these five things to remove unit and these five things, in reverse, to install a new unit."

I want to know how to test a crank position sensor to see if it died. A throttle position sensor to determine if it's getting power, etc. Is that kind of info on road glide.org, and, if so, could you be so kind as to point me in that direction?

I'm over being pissed that the RG left me stranded and pushing it home in front of all my neighbors, and I've moved on to being excited to try to fix the thing and get back to some nice summer rides.

So, any help you could provide would be much appreciated! That said, any ideas of things I should consider but haven't mentioned above would be great, too!

Welcome!! I'm sure somebody will help, lots of knowledge on here. I'd say if you have spark and air maybe prime it with gas when you try to start. From reading your post you sound like you aren't afraid to dive in, good for you and good luck.

BigDoug,

Thanks for the welcome and well wishes! It'll likely be a process of elimination, but I'm not big on throwing parts/$$ at the problem until something fixes it.

I'm confident the crew here will help get me back on the road.

Thanks for the idea on priming it - you reminded me I have a can of starter fluid out in the garage! I'll do that tomorrow to see if it starts. One thing the service manual mentioned was a plugged fuel filter could cause a non-starting bike. It looks like a remove/replace-with-new procedure and not a serviceable item. If starter fluid works, I'll likely buy a new fuel filter to see if the flow is choked off. Awful tough to get Mr. BANG to show up at the party if he can't drink his bang juice!

Something I failed to mention initially is that I also checked out the suspect fuses today. Although the 15A fuel pump and ECM fuses were good, they were a bit dirty on the metal posts, so I replaced them with new ones. The 15A ignition fuse on the left side in the fuse box was good, too.

I'd too go with starting fluid for the bang, most times when injectors go it one lungs with idiot lights, so this may be deeper, you know how to check spark

Fuel supply line from pump in tank sometimes splits so you get no fuel delivery. Enthanol being the cause.

If it's fuel injected, when you turn the key on and kill button on, you should hear the fuel pump running in the tank and then pump up and stop. If it continues to run without stopping, a hole is probably worn in the supply line in the tank. Very common on older bikes. Heck, it even happens on newer bikes. After that, there is a multitude of problems like crank sensor, throttle sensor, etc.

BigDoug/Reds4, It's ALIVE! . . . briefly. The starter fluid worked! Thanks for the idea, guys.

So, I've a fuel delivery issue. Smarty, the fuel pump primes for a few seconds and then shuts off as it always has. So, it at least thinks it's priming the system.

JayRay, you may be on to something with the cracked line, though, per Smarty, a cracked line would cause the fuel pump to continually prime at start up.

I'm inclined to buy a new fuel filter to see if that's plugged up. But, in the interest of not replacing the entire fuel delivery system piece-by-piece until I find the culprit, I'm open to any troubleshooting advice the crew has for me.

Thanks for getting me this far!

Very well could be the fuel filter. If it is pressuring up, that's the next thing I would check. Also, open the tank cap and listen for leaks. It has to build up to a certain pressure for it to start.

If the air filter was never maintained then chances are the fuel filter was never changed either so changing the fuel filter is a good idea. Also check for the fuel line cracks in the fuel tank and the fuel filter housing being warped.
Usually if there is a crack fuel line or warped fuel filter housing there will be signs that there is a problem, the signs would be engine popping or backfiring like you got some bad fuel and lack of power, also the bike will run good when the tank is full but as the fuel level in the tank drops the issues returns because the fuel drops below the fuel line crack and the system starts to suck air. If none of these symptom happened before the bike shut down then chances are you don't have a problem with the fuel lines or fuel filter housing.
A fuel pressure gauge will tell you if you are getting enough fuel PSI if you're still having problems after doing the work in the fuel tank.
If you're still having problems check the fuel injectors and the injector wiring.
