Question about 2005 Harley Davidson FLHR - FLHRI Road King

1 Answer

Bike turns over and has good fire. Will only start with starting fluid. I know it isn't good for it, but it was the quickest way to confirm spark plugs were working

    A little more of the story. I bought the bike in January. I have been babying the battery since day 1. When I stopped for gas this morning it finally quit on me. I put in a new battery today. It cranked and cranked but never fired up. I finally got the ether to give it a shot. It fired right up. I drove it home (about 25 miles). Once it was in the garage I tried to start it up. Same issue. I have been thinking that the battery was just too weak from sitting on a shelf. Had the battery tender on it for 1.5 hours and it still hasn't given me the green light. Hopefully this was all due to my oversight.

Carb is most likely needing a cleaning. Try throttle body cleaner once it starts......

SOURCE: Replaced positive battery cable + spark=bike will not fire up

I am afraid to make assumptions as to what else you have checked due to some negative feedback. Did you LOAD check the Battery? Did you check and clean your grounds? If you have done all of that the next logical problem is the solenoid, which can be rebuilt.

SOURCE: bike will crank over but will not start.

It sounds like you are losing power to your coil. This is why it will fire only once and then quit. To verify this, connect a test light to the small connection on your coil that has the white wires runing to it. Turn on the switch, the test light should come on. Now press the start button. If the test light goes off and stays off, this is what is happening. It may come back on after a few seconds. If so, you have a short somewhere causing your igniton circuit breaker to trip or the circuit breaker is bad or you have a bad ignition control unit. The control unit is very difficult to diagnos since Harley uses a particular type of meter to do their testing with.

Using a DVOM (digital volt ohm meter) test the resistance of the primary circuit of the coil. Remove the white wires and pink wires from the small connections. Now, put the meter in "R X 1" scale. Touch one lead lead of the meter to each of the connections. You should read about 3-4 ohms of resistance. Any more or less than this, your coil is bad and you need a new one.

2005 roadstar silverado starting riding bike cut out, now it wont start, turns over perfect, any ideas?

Hi, you need to first determine if the problem is ignition or fuel related. Spray some starting fluid into the air filter inlet then try to start it. You need to open the throttle 1/4 to 1/2 open. If the engine fires for a few seconds, you have a fuel delivery problem. If the engine does not fire at all, you'll need to verify you have no spark. Then you'll know it's an electrical/ignition problem.

Why wont my 2011 jeep grand cherokee wont start

Okay, the possibilities are great. need to narrow it down a little.
If it fails to crank over it is likely the battery.
If it cranks over ok, but fails to start it is either lack of fuel or lack of spark.
the Quickest way to identify lack of fuel or lack of spark is to spray in a 2 second dose of starting fluid into the air intake. If it fires up then dies in this test it is lack of fuel most common suspect is fuel pump relay or fuel pump.
If it fails to fire up on the starting fluid test it is lack of spark. Electronic ignition trouble shoot procedure from your shop manual for your VIN number will be required.

check crank position sensor or immobiliser system as you have not spark at the right time. Immobiliser may be a battery problem in the key unit. Have the codes read

Turns over but won't fire

If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

How do you know if the magneto is bad

If you have a spark, you don't have a "Magneto" problem, Check the air filter and the 2 stoke oil tank. And check that the spark plug is wet, if it isn't firing and the plug isn't wet, you don't have any fuel getting to the combustion chamber.

My bike isn't getting fire I smell gas when I am turning it over spark plug is good and I need to know if its the cap I snap on the plug or a coil how do it narrow it down

you need to multi meter test for resistance (OHMS) your dealer bike shop or service manual should have the expected range readings and should give reasonable idea how to test each stator or the coil or ignition coil - I have no idea what your bike is to offer any more specific but this is broadly speaking how you test the electrical side of ignition
pretty much any multi meter with OHMS setting will give you enough info on a fault as when you test it will be way out of spec range if is at fault for instance I just tested my own bikes stator and one of the readings was meant to be within 700 - 1050 range and the reading I got was 10 so accuracy of meter not to important when looking for faults if it is faulty it will show up easily
when you say spark plug is good do you mean you know plug is new or the plug is sparking well when you kick over or try to start bike with plug out of motor ?
maybe write back if you like with info such as what bike are we talking about and is the plug sparking at all etc
good luck regards Jamie

Can't start

Determine if it's more of a spark problem or more of a fuel problem.

If it turns over vigorously, then the battery and starter is good.

If it won't start even though it is turning over, then I would spray some starting fluid into the intake and see if it starts momentarily or for a few seconds.

If it does start, then you know you have spark, but no fuel delivery. In which case it could be a bad fuel pump or fuel injectors aren't firing.

If it doesn't start even with the starting fluid, then you may not have spark.

Good luck on this diagnosis.

1988 Chevy Truck suddenly stopped running while running 60 mph down the highway. Just quit. Now the engine turns, but doesn't fire. Tried starting fluid. Won't fire. Check spark, and I have spark. So...

If you're certain you have spark then try the starting fluid again strait into the throttle body with someone immediately starting it. Your compression may be another issue to look at but this is uncommon to stop you while running down the road. You might want to check the compression though. Take off a valve cover to confirm that the valves are still moving to help rule out a broken timing chain.
