Hi Mike, and the usual suspects are:
1. Spark plugs in bad condition or partially fouled.
2. Spark plug cables in bad condition or leaking.
3. Spark plug gap to close or to wide.
4. Faulty ignition coil, module and or sensor.
5. Battery nearly discharged.
6. Damaged wire or loose connections at battery terminals,
ignition coil, or plug between ignition sensor and module.
7. Intermittent short circuit due to damaged wire insulation.
8. Water or dirt in fuel system, carburetor or filter.
9. Fuel tank vent system plugged or carburetor vent line closed off.
10. Carburetor controls misadjusted.
11. Damaged carburetor.
12. Loose or dirty ignition module connector at crankcase.
13. Faulty MAP, CKP, and or CMP sensors.
14. Incorrect valve timing.
15. Weak or broken valve springs.
16. Damage intake or exhaust vale.
As for the fuel valve leak they make a rebuild it for it. Good luck

SOURCE: fuel leak at bottom of petcock valve 2000 fatboy

Sounds to me like a cracked fuel line. No leaks when sitting still but add the torque of the engine turning over and the vibration and the line flexes enough to leak. If not a fuel line, the weld may be cracked where the petcock mounts to the tank or the petcock itself may be cracked. Is the petcock water trap screwed on tightly?

SOURCE: oil leak

Welcome to harley ownership, been through this often on my bikes. The air that is displaced in the crankcase during operation builds up pressure and travels through the motor out to your air cleaner. Based on the age of the bike (no disrespect whatsoever), the umbrella seals more than likely could use replacing. What happens is the displaced air is really a mist of oil and air and as this travels up through the engine its last stop is the umbrella seals, which look like a very small umbrella with a short shaft. The bad news is that unless you want dig into the top end of your motor you are probably going to more comfortable having your shop replace these for you. If you decide to do it yourself repost and we will go from there. Also there are some after market parts that work pretty well too to help most are around $200. Hope this helps.

This is just a guess, but the problem may be with the crank and/or cam sensors.

Ford Taurus being a ********


Lets start at the beginning.
You say it cranks but will not start, right ?
The warning lights are supposed to come on with the key on and then go off once the engine starts.
If the engine cranks but will not start, someone will need to figure out if it is lacking fuel to the injectors or spark to the plugs, or something else. One way we check it is to look for spark at the plugs, check the fuel pressure, and try starting fluid in the throttle body.

Loosing mpg went from 35 mpg to 25 mpg to 20 mpg over a period of 6 months


do you ever notice an extended crank (takes longer to start) if you drive it until warm shut it of for 15 minutes and then try to start?

The first think I would look at is the fuel pressure regulator. It will be on the drivers side of the engine right below where the throttle cables attach to the throttle body and near the rear valve cover. There will be a smaller diameter hose coming out of it that does not have a hose clamp on it. Remove that hose and see if gas comes out of the pressure regulator. You may have to start the vehicle and let it run for a little bit. If gas comes out of the regulator you found the problem and it will need to be replaced.

1999 blazer wont start??


Your battery is either faulty or ther is a parasitic drain, have it checked out at parts house. With a good battery installed, spray some starter fluid into intake housing. If it starts, then dies, you have fuel pressure/delivery problems. Can you hear the fuel pump run when you turn on the key? Hope this helps.
