I have seen a couple of cases where if the strainer on the pump inlet gets totally dry, it takes a *long* time to fill up enough for the pump to prime.

So….its running!

 

Took the tank back off and did a fuel pump flow test with the new Ducati filter and the old NAPA looking filter. Noticed that the Ducati filter flowed less water. Installed the old filter back on and was able to build pressure to 43psi after priming a few times. It fired up immediately! Went to NAPA and bought a 3032 Gold filter, installed it and same pressure characteristics of the old filter.

 

I can't believe the culprit was the Ducati filter.

 

Admittedly, I did buy the new filter from eBay to save a few bucks, but from a highly rated seller. I would have never thought a new filter could be bad. Lesson learned.

 

So after getting it running again I took it out for a test ride. Seems to idle and run a little better. Could be a combination of valve adjustment and new filter.

 

But the original issue still persists. I think it even has gotten worse. Before it would choke a 6500rpm at ¾ throttle but now it seems to choke earlier and at ½ throttle. I did connect JPDiag and hit reset TPS but now I'm thinking maybe the process is not as simple as that. I did see that the TPS is at 3.2 at fully close throttle and 85 at fully open. These were the same numbers I saw before “resetting” the TPS as well. TPS voltage measured at the connector at closed throttle is 0.39V and 4.20V fully open. Just to confirm, these measurements are supposed to be taken by twisting the grip right and not by twisting where the throttle cable attaches to on the engine right?

 

I got the cable to use with JPDiag and TuneECU over the weekend. I had a bunch of error codes so I cleared it. After I got it running, I pulled the codes again and code P0351 “ignition coil 1 circuit malfunction”. Maybe I'll clear it again, and see if it shows up again by cycling the ignition without starting it. Which coil is coil 1 and how do I go about testing it?

 

What else can I test to get rid of the running problem?

 

Thanks all!
