My 30 year old Yamaha 75 HP outboard motor won't start despite new plugs, clean fuel and a fully charged battery. Why is this so?


Spare plug, remove spark plug cap and insert spare plug in cap. Place on metal part engine and swing engine, you are looking for a spark at plug . Do not hold plug, if electrics fine it will give you a nasty kick whispichbyou will remember. If no spark then electrics need investigating.

I have a 2006 20' boat with a 4.3L Vortex engine. The started needed to replaced and after further inspection the starter looked rusty. Removed spark plugs on left side of engine and rusty water came out...


he bore on that side will be rusty so the engine has limited life
the water could be from a cracked head or head gasket problem
if the engine is at water line in the boat
, if there is no exhaust flaps at the rear of the boat , then on shutting down the engine water could have been sucked back up the exhaust on that side into the engine
( cooling manifold creates a vacuum which will suck in the water

1978 YAMAHA RD400E NO SPARK ON ONE CYLINDER BIKE RUNS ON


Hello,

Remove both sparkplugs from engine. Plug them back in the sparkplug cables and let them rest on the engine.
Make sure your battery is well charged.
Check for sparks while kick-starting...
Interchange the sparkplugs in the cables:
-Same plug give sparks: replace the spark plugs.
-Same side of engine sparks: interchange the low-voltage connector at the ignition coils.
Give it a try:
Same engine side sparks: Replace the defective ignition coil.
Other side of the engine sparks: Check the circuit harness for loose connectors, and/or Clean-replace the breaker points ( left side of the engine carter ).

I replaced my spark plug wires on my 1996 chevy truck. may have crossed one,need a diagram from the spark plugs to the distributer cap.


Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
Spark plug order in engine, starting from Front going back, Passenger side:
2-4-6-8

Yamaha warrior won't start


If you are getting a nice bright blue spark then no, the last time I had a problem like this it was sugar in my tank. If you taste a bit off your finger and it is the slightest bit sweet, then some one has sugared your tank. If so just flush the tank with a little fresh fuel and then flush the carb, and fuel lines by spinning the engine over for a bit then try to start again.
Is yours an electronic ignition or points. If points gap could be wrong or even timing slipped. That has happened to me also.

Spark plug order


If you are sitting on the bike, cylinder 1 is on your left then 2,3,4....looking at the coils, the left coil- left lead goes to no1cylinder. right lead goes to cylinder4. Right coil- left lead to cylinder 2, right lead to cylinder 3.
Hope it helps you.
