Question about 1998 Honda VFR 800

2 Answers

Engine won't start

Battery is ok as it works on other bike, think it is a fuel problem. Not getting to the engine.
All lights, ignition work and engine tries to start on start up, think no fuel present or getting from tank to engine. Had a look at the pipes but havent removed them as tank is nearly full. Has anyone had such a problem before and can anyone give me some advice. Paul

I have a 2000 800fix and recently had a similar problem, turned out to be as simple as corroded spades at the fuel pump. i lifted tank at front and bridged the pump to the battery to check it still ran first, be careful running pump dry though as it uses fuel to cool, then cleaned the connection block and spades and voila!
Its a little difficult to get too though as pump is located under tank at towards the back of bike and was tricky to get too without removing tank completely, not sure if same layout on 98 model, but worth a try

If you can locate the fuel pump  check to see that it is working  when cranking the bike over this is the only time that the pump will work as it is pulsed off of a crank trigger touch it with your hand or have  a buddy  do this while u turn it over  if u can feel it working its probably  fine and should check tank and fuel outlet  for problems next

My honda ran well until I hooked tail lights up and now I have neutral light and oil light no other lights work also it don't fire when I crank it lights come on as long as its cranking


Hi, Steve and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Faulty fuel pump fuse or relay.
11. Security alarm needs a reset.

Yamaha yellow engine warning light on YZF R125


Hi, Anonymous, if your ECU believed your engine was endangered of being damaged it would go into "LIMP" mode 5-10 mph only, it should be noted that the reasons your EFI light stays on constantly or flashes and your bike will or will not start and may turn over or not, these conditions will vary from bike to bike depending on the year, make, and model and you should always refer to your owners/service manual for proper diagnostic procedures. It should also be noted that any type of prior work done to the bike or an abnormal event occurrence IE: adding accessories, electrical curiosity/adventures, laying bike down/crashes, rainstorms/bike washings just before EFI light issues started can be significant hints/aids into tracking down the gremlin, also carry the appropriate jumper wire to access fault codes to reduce the risk of being stranded or towed, that being said the usual suspects are:
1. Faulty Fuel Pump, fuse or system relay switch.
2. Battery starting to fail due to old age/damage, perform a load test.
3. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Faulty switches/sensors: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. Broken wire or worn insulation exposing wire to a ground situation especially inside wire harness at tight bends around fairing brackets, under dash panels, under fuel tanks over cylinder heads etc. Many harnesses are open on the ends that will allow water to enter and accumulate at v-bends.
Dielectric grease and contact cleaner are your best friends for wire/cable/harness connectors, look for corroded, broken, or loose pins/sockets.

Just won't start! fuel pump ok, filter ok, psi ok, turns over just won.t start


You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, or a list of other things.
Even the fuel pump.
If this is a vortec V6 it takes at least 60psi to cover the injectors.

Car turns over but won't start


Which engine?

I would first check the following:
Are you getting spark at the spark plugs? If not, check the ignition coil or coil pack.
Are you getting fuel to the engine? Make sure there is fuel in the tank, and that the fuel pump is working.
Check all your fuses to make sure they are OK. A blown fuse to any critical engine component (ECM, ignition, fuel supply) will prevent a vehicle from starting or running.

Problem starting sv650s


remove spark plugs from block, place tread on block, turn over engine, best if blue, white ok, orange spark is bad, if you are getting orange, your ignition system is weak, usually the coil, and needs to be replaced. also make sure to take out the plugs after attempting to start, andmake sure they are wet and getting fuel.

My bike wont start


I have the same problem and same model (2008 KTM Adventure 990 S) so injection, not carburator.
I didn't start the engine for three months. I bought a brand new battery. Lights, fuel pump and everything seemed to be ok at the first key turn. But when you try to turn it even more to definitely start the engine, ignition fails. I think the electric engine of the starter is not working properly.
I tried to start the engine driving down the slope and releasing the clutch in 2nd gear at aprox 30 km/h and it started successfully.
I left it idle until became hot (15 min aprox) and the turned it off.
however it didn't start again when trying the ignition button.
Any ideas?

Bike wont start


when I tried to start it yesterday it would not start; pushing the ignition causes just one *click* sound and then nothing. The battery is reading 12.65V or so so that seems fine. I did some research and I think it's either along the lines of the spark plug(or ignition area) or maybe water in the float bowls from fueling up(?). I tried it again today and this time there was no *click* sound. I also noticed that the -neutral- and -check engine oil- lights which normally light up quickly at start up take a few seconds before lighting up. Now I think it's more in the electrical section but not exactly sure which area. I'm going to take a look at the spark plug and maybe try to drain any water out, but was wondering if anyone had any other ideas? ,When you press start, the churning sound you (typically) hear is from the starter motor forcibly turning the crankshaft. While the starter is physically turning the engine, the engine is also injecting the fuel/air mixture into the cylinders and firing the spark plugs. If the plugs successfully ignite the incoming fuel/air mixture, the engine will begin turning itself over. If you press the button and nothing happens, or you just hear a click, the starter motor is not cranking the engine. The click you heard was probably the starter solenoid attempting to engage the starter to the flywheel of the crankshaft. The problem is probably the starter. It may be a bad battery. Reading the open voltage with no load on the battery tells you nothing. Put the voltmeter across the battery terminals and read the voltage while holding the Start button.,,,
