I recently bought a 2006 FXDWGI - Dyna Wide Glide. Awesome bike - however I am running into problems with her. The previous owner rode her like 200 miles in 2 years as his priorities changed with work and family. Because the bike sat for so long, I got a fuel leak from the tank. I changed the fuel check valve, and the fuel line from it. Once I got everything buttoned up, and gassed her up, I was chomping on the bite to ride her. (While I was waiting for parts, I did a complete tune up on her - new spark plugs, oil filter, and changed all the fluids.)

Well, my problem is that she won't start. I'm 99% sure I hooked up the fuel pump connections to the top plate. When I disconnected the fuel line from the quick disconnect, there was fuel in the line. She'll turn over, but not catch. She is acting like she isn't getting any fuel, but there is fuel going to the fuel line. I also threw her on the battery charger, thinking maybe she was low on charge. Once charged, she'll turn over and over, but no catching.

Any advice on how to trouble shoot this?

 

Can you hear the fuel pump prime when you first turn the key?
Quick disconnect seated properly?
Check valve upside down?
Everything ok inside the tank?

 

First you need a service manual. That will help you trouble shoot your bike. A quick check would be to spray starter fluid in the air filter and crank if it fires up you got a fuel problem (not the best for your bike though). Check for spark at the plugs. Check compression. The fuel system you can prolly you tube there a few things that can be wrong there. When you turn the bike to on does the fuel system fire up?? you should hear it.

 

^This.

 

think backwards and reverse everything you did in your head. if you can make only one change at a time unless you know exactly what your doing. Not doubting you but u seem to have limited mechanic experience. Get the shop manual.

There is the very real possibility the pump is dead out of the box. You could have popped a fuse. Im assuming the battery was connected. no fuel or bad fuel, remove the check from the system to see if it fires. debris in the tank clogging the pickup.

tons of variables but yours problem seems like a basic one that didnt manifest itself until you tore into the bike.

 

Did you cross your spark plug wires?

 

I had the tune up done before I got the parts to change the Fuel check valve with line, and the new fuel line. I know to only change one spark plug at a time to avoid crossing the lines. The bike has spark and compression.

1Qcktrufflesnuffler - I think that you are right that it does not sound like it is priming. I've been thinking about this problem all day long - the only thing I could think of is that maybe I didn't connect the fuel pump wiring harness back up to the underside of the top plate as I was putting on the new gasket. That would cause it not to prime.

 

Dysfunctional1 ~ I DIDN'T change the fuel pump. I only changed the fuel check valve (which was in a kit) and the fuel line from the quick disconnect to the fuel injectors. In order to install the check valve line, I had to completely drain the fuel tank via the crossover line (which had fresh fuel in it). There was no debris in the tank. I filled up the tank with fresh 91 octane fuel I had just purchased from the gas station a block away.





I did only make one change at at time and finished that through completion. The last thing I did was mess with the fuel check valve.

 

If it worked before...and now it doesn’t...something you did is causing it...open it back up and recheck everything...there is a little green washer that needs to be on that line, and you have to buy it separately...was it there? This washer seals the line to the pump....I know I just pulled my pump to have my tank painted....and had to replace a leaking quick disconnect on my other dyna so I know it’s suppose to be there, on one of the bikes, I found it lying in the tank as it falls off as soon as you disconnect the line from the pump. Change the filter while your in there...the fuel sock should be ok...

 

Thanks for your informative reply and help! When I took off the old check valve line, there was a green washer inside the fuel assembly - where the tube was inserted. I purchased the replacement through JPCycles.com https://www.jpcycles.com/product/100...-oem-62194-04b. It didn't have the green washer - but had a black one. Do I specifically need a "green" washer? This was also the efi fuel line I installed. https://www.jpcycles.com/product/721-852/efi-fuel-line When I was inside the tank, I was careful not to mess with anything except the check valve and the line.

When I turn it to the ignition, I can hear the fuel pump prime. It will turn over and catch for about a second or two, and than sputter. So I know for sure it is a fuel issue somewhere.

So here are a few questions.... Can I narrow the problem down to either the efi fuel line or the check valve? Can I undo the efi fuel line from the fuel rail and keep the check valve quick disconnect connected and than turn on the ignition switch? If I have pressure/ flow, than I know it would be a fuel line problem?? Would this narrow it down? It would take 5 minutes to figure if the problem is inside or outside of the tank.
