No the fuel pump will not fail more than once. When a fuel pump goes out it just goes. Will not work after that what so ever. Sounds like bad gas lines. I had this problem. I replaced my old gas line after the old one cracked when I did this I cut the new on to long. When I put my tank back on the old one pinched. It would run fine for a few min then sputter and die as the gas in the line ran out. I let it sit for a min and more gas filled the line and would start the process over. Try replacing the fuel lines and make sure they are cut to the right length and do not kink when the tank is on. It could also be a dirty petcock. I had let my bike sit for 6 months while in another state and the gat tank got dirty somehow. I got it running and same problem putters and dies. Neighbor took out the petcock and used an air hose to clean it out and it worked like new.

check the fuel filter it sounds like it's pluged and causing too much back presure this is causing an over load in the fuel pump causing it to stop working or to presure lock

I have a 2006 audi a4 3.0 when temperature outside drops below 40 degrees it will not start ,when the temperature outside gets around 45 degrees it starts and runs with no problem . screen reads ok


I assume from the question that the engine is cranking over but will not start. Hence there is no issue with the starter motor on a very cold start.

At 40 degrees F you are getting closer to freezing. When this happens again I would check the operation of the fuel pump.
Take the fuel cap off the fuel tank and have someone switch the ignition on and off a few times. (just the ignition - don't start the engine up). Turn it on for 10 seconds or so and then off. If you listen at the fuel filler opening with the cap off you will be able to hear if the fuel pump starts and stops. If it is working it should start and then stop a few seconds later each time you switch on the ignition because the computer shuts it down in a few seconds if the engine is not started.

If the fuel pump is operating I would be looking for some electrical gremlins. You would need to check that the fuel injectors are getting power and that the spark plugs are also.

Ideally you would need to a quality scan tool connected to the car when you have this very cold no start condition whilst trying to start the car to see what faults may be present because it should pick up some malfunction if the start problem goes away when the temp rises a few degrees over 40F.

I have an07 street glide I need the wiring diagram for the starting switch system


Is the bike in gear with the jiffy stand down? Safety circuit will stop bike from starting. Also, is the run switch turned on (the one on the right hand handlebar switch)? Have you any error codes in the speedometer diagnostics? The start switch on the bars do fail so could be that. Listen for a click from the start relay under the side cover while pressing the start switch. No click could mean faulty start switch. If you here a click, then check for 12 volts at the small terminal on the starter solinoid. If missing, starter relay may be at fault. If present, the starter solinoid is faulty. Listen for the fuel pump running after turning on run switch. Pump should run for a few seconds and then stop. If pump not running, then run switch may be at fault.

1200 custom sportster stops running when it get warm


Sounds like it is possibly the cam sensor. It is located under the round cover on the lower right side of the engine. The cover is held on by 2 rivets. If this is indeed the problem, you will have to re-time the bike after replacing the sensor.

Power shuts down while riding, then a few seconds later starts back up. Some times, when trying to start bike in the morning the fuel injuctor will not activate when switch is turned on, after messing...


Fuel injection usually has a high pressure electric pump, which usually runs off a relay so that it does not melt the ignition switch, and so that it is easier to cut out if the bike tips. Relay could be going bad, or there could be a tilt sensor loose or going bad.

Won't re-start after stopping for gas/rest during road trip.


This problem sounds like you have a fuel pump over heating and shuts of the relay. When it cools off the relay kicks in and you can restart your vehicle. Replace your fuel pump and the problem will go away.

No power to the fuel pump fuse 07 sportster 1200


Power to the fuel pump comes from the system relay via the fuel pump fuse. The power to the relay contact is from the ignition switch via the ECM fuse. The relay is activated with power form the ECM itself and is also controlled by the "stop/run" switch on the right handlebar control, so make sure it is switched to "run".
