He said he has the supertuner from HD. You can't 'Take it out' so to speak cuz it's not 'in there'. SuperTuner like it's predecesor SERT is SW that let's you tune the onboard ECU. So once changed that's it, not like a PC3 or any fuel pak it doesnt stay on your bike.

Anyway's, when you checked your cable conx did you also check the other ends, on the frame and starter etc. to make sure they were tight also?
If bad fuel screwed up your pump then I'd think that maybe your injectors maybe clogged. Spraying cleaner in the throttlebody won't touch the injectors. Might try injector cleaner in the tank, or replace injectors with the new 25 degree cones as stated in a HD bulletin for that yr.

Also, you thru a crank position code, now could have been cause of other probs but that sensor not hard to change just follow the manual.

it was the fuel flow that was the issue between the stock and 25 injectors.. he has a SERT in the bike that adjusts the flows and corrects the problems... never the less, if it is a clogged injector i would upgrade with the new on on replacement

 

I had a problem with idling recently, engine management said sensor trouble, i forget which tho, dealership replaced sensor and did a re-map, but it didn't help the problem, then they discovered a split hose on the air cleaner and obviously replaced it. It seems fine now.

 

Do a search on M-1185 which is the Harley TSB for the 8 degree fuel injector issue. There should be lots of posts on here and a copy of the bulletin. Check your build date and look at your injecors under your tank to see what part numbers you have in there. I had the 8* oones and they ran like chit and had them swapped for the 25* under warranty at my 1,000 mile service.

One thing could be you have clogged the injectors with the bad gas.

SERVICE BULLETIN
M-1185 February 20, 2006
FUEL INJECTOR/CALIBRATION CHANGES FOR 2006 1450cc
BIG TWINS
®
Purpose
It has recently been determined that the 8
°
angle cone spray
fuel injectors used on 2006 1450cc Big Twins may cause cold
start and/or driveability problems on some motorcycles.
In the interest of promoting customer satisfaction, the 25
°
angle cone spray fuel injectors used on CVO 103 cu. in.
(1690cc) motors will be installed on all production Big Twins
beginning on or around February 13, 2006.
Additionally, Harley-Davidson will provide for the installation
of 25
°
angle cone spray fuel injectors on those motorcycles
where use of the 8
°
fuel injectors (part number 27625-06) is
determined to be directly responsible for cold start and/or
driveability problems. See REQUIRED DEALER ACTION.
NOTE
Due to changes in the manufacturing process, the part number
of the 25
°
angle cone spray fuel injector is changing from
27709-06 to 27709-06A. This fuel injector also will be
stamped with the words “25 DEG” for easy identification. See
Figure 1.
Motorcycles Affected
Only 2006 1450cc Big Twin model motorcycles that exhibit
cold start and/or driveability problems directly related to use
of 8
°
angle cone spray fuel injectors (including those subsequently
equipped with P&A Screamin’ Eagle 1450cc or
1550cc Performance Kits).
Required Dealer Action
1. Adhere to the flow chart in Figure 2 when handling customer
complaints regarding cold start and/or driveability
problems on affected motorcycles.
2. If the flow chart indicates that the fuel injectors are the
source of the problem, check the part numbers stamped
on the fuel injectors. While standing on the left side of
the motorcycle, the part number on the rear fuel injector
can be easily read with the aid of a flashlight.
3. If required, remove both 8
°
angle cone spray fuel injectors
following the procedure in the applicable 2006 Service
Manual. Install 25
°
fuel injectors, either part number
27709-06 or 27709-06A.

In the interest of preserving customer safety and satisfaction, always check for outstanding recalls whenever any motorcycle is brought into your
dealership for either maintenance or service.

NOTE
Always replace both 8
°
angle cone spray fuel injectors on
affected motorcycles. Never mix 8
°
and 25
°
fuel injectors on
the same motorcycle.
NOTE
If the part numbers on the fuel injectors are rubbed off or otherwise
unreadable, count the number of orifices or holes in
the injector nozzle. The 8
°
angle cone spray fuel injector has
just three holes, while the 25
°
has six. See NOZZLE END in
Figure 1.
4. Update the ECM calibration. For those motorcycles
equipped with P&A Screamin’ Eagle 1450cc or 1550cc
Performance Kits, refer to h-dnet.com for the correct calibration
P/N.
Credit Procedure
Complete a separate warranty claim for each vehicle
serviced. Reference Service Bulletin M-1185 in the
“Comments” or “Notes” section and be sure to include the VIN
of the vehicle on which the service was performed. Fill in the
rest of the claim as follows:
Performance calibrations require pre-authorization from Technical
Service to be considered for warranty coverage unless
listed on the SWR.
Upon receipt of the properly completed claim, you will receive
the labor credit shown above.

Correct condition or install
compatible components.
Are cold start or driveability
problems still evident?
Check the following:
● Fuel has the recommended octane rating and is not
contaminated.
● IAC operation.
● Spark plug condition.
● Engine is configured correctly (with the appropriate air
cleaner and exhaust).
● Vehicle configuration is supported by the correct
calibration. Refer to Calibration Information on h-dnet.com.
Does the vehicle pass inspection?
YES NO
Check fuel pressure. Is
fuel pressure between
58-62 psi?
YES NO
Replace the 8° fuel
injectors with 25°
fuel injectors.
Update ECM
calibration.
Check part numbers
stamped on fuel injectors.
Are 8° or 25° angle cone spray
fuel injectors installed?

Did the bike run fine prior to fuel pump failure? You replaced the fuel pump, that's the one thing that would be common to fuel delivery. Is the fuel pickup tube picking up air into the pump (causing cavitation) and introducing air to the injectors I'm not up to speed on how to purge the air out of a pressurized fuel system. But that's what it sounds like to me. My $.02.

 

Did you pull the spark plugs and look at them? It was a simple $8.68 fix for my problem ...

With the bike running, spray carb cleaner around the intake gaskets to see if they are leaking. I Had to do mine, I also took the time to clean out my throttle body and injectors. My bike already had the 25 degree injectors from the factory, it was built Feb of 06'. FYI after you disconect the battery or the throttle body sensors, you are supposed to turn the key to Run and then off again and then run to calibrate the it. I think it calibrates the TPS but not sure

 

A couple of things to check, wiring to fuel injectors, if they have no service loop the wires can be pulled as the engine rocks in the rubber mounts, the wires insulation will stretch but the wire itself will break, it won't be visible because you'll only see the insulation and not the wire. Check them as if you were checking ignition wires, point "A" to point "B" with an ohm meter moving and wiggling the wires around as your reading resistance.

Internal fuel tank lines may have a pinhole and are sucking in air: https://www.hdforums.com/forum/dyna-...fuel-line.html

You have SEII slip ons, a SE stage 1 a/c with no tuning? I think these bikes need tuning with the stock intake and exhaust.

Did you do any modifications before this started? Also how is the battery?
