fuel line from the bottom of the tank to the injector block seems ok fuel flows free thru it one of the first things I checked. I'm leaning more to some problem inside the tank with something the pump does run but i'm unsure if I only have flow but no pressure doe's that make sense ?

Check fuel pressure like this....

Check fuel pressure like this....

A sacrificial fuel line and trip to the hardware store.  I believe 58 lbs. +/- a couple is the desired fuel pressure.

I may end up having to do that I was wondering if anyone made some type of guage to check it I'm with you make your own !

[Keats]

Ditto

check fuel pressure............


if it runs then it has to be something with injectors.

what is the fuel pressure? 55 - 62 PSI?

the bike will not start with 35 - 40 PSI,  This recently happened on a friends bike.


PS. careful taking out fuel pump with line routing and the torquing of screws (console)

use new screws and follow torque pattern. or may have a lap full of gas like my buddy.

For about $450.00, Jims will sell you a kit.  Or for about $30.00 you can make your own (or less depending on your shop stash).

I'm probably way off here as this comes from a single bike and incident several years ago.  But I thought I remembered the following from a bike with an ECM and TSSM that weren't mated (though there's not a specific mating on the Marelli bikes, just the Delphi bikes).

Guy I knew had a Road King whose TSSM took a dump.  He got a used TSSM.  Pretty sure I remember the bike still starting and the signals and other lights still working.  Just no alarm function nor ability to programs fobs to the alarm.

Don't take this as gospel.  Was a long time ago and only one weekend afternoon he was telling me about it.  But that's the recollection.

Since this is a carb conversion, is the fuel pump new from HD? Could it have failed?

[SILVER ROAD KING]

Yes the pump is new along with all of the other parts installed around febuary of this year new wiring, new T Max, new HPI throttle body, injectors, ect,ect done a total conversion from a Road King to a FLHT with all new Harley parts except what I mentioned

I have another question for you guys. tonight I pulled the fuel line off of the injector mount block on top of the intake with a cup in hand ready to catch what gas I thought would be in the line from the pump to the point where I unplugged it I soon found out that a cup was not going to hold it it never quit running is this normal ? and another thing while I was sitting there letting it run in a gas can I had a thought ! lets see if the pump would really made the gas squirt if I turned the switch on. NOPE just trickle no different than the line just being unplugged.

The problem is with the pump but it is running there has to be a line that has come off or something has went bad with the pump I'm going to pump the gas out of the tank tomorrow night after work and pull the pump and maybe I will find the problem everyone has been very helpful with your suggestions and ideas Thanks

This is the inside of an Electra Glide tank...

Target range is 55-62 psi.

[sadunbar]

Target range is 55-62 psi.

Otherwise known as 58 psi +/- a couple few....more or less   

(of course, only after you pull the swing arm...)

it is proobly the oil presure sender only thing that cuts fuel off to injecters  un plug and try

I got this message in a pm from scooter6262.  Makes sense so I thought I would pass along.

When did a low oil pressured signal for a fuel cut off begin?

Curious about that myself....  Can more details be shared?

Just checked the 2009, 2010 and 2011 model year tech bulletins and found no mention.  So if it was incorporated was 06, 07 or 08.  But I've never heard of oil pressure triggered fuel cut off being added.  As low as TC oil pressure used to be at idle it would have shut off a lot of bikes over the years .

This cannot be right.........

low oil levels with idle would have caused shut down on many bikes......

going to the garage and drain the oil out of the bike and see if it starts...........
