check your injection system (fuel filter,injectors).
There's a dipstick to measure it just like oil. Add through the tube with the engine running so you don't get a false full reading.
Count Dracula had three vampiresses in his castle. This hardly seems like a castle full.
Defective fuel pump, or clogged fuel filter.
Float in tank is stuck or defective gauge Sounds like the sending unit is stuck in the full position.
Sounds like the fuel pump. Maybe you have some wires crossed.
This sounds like the power brake vacuum booster going bad.
Sure if you like a jeep.
oh yea,,, specially when it Glows with its full glory like ''NOOR''..its glorious icy rays ahh !! seems to be a view of heaven..
The Toyota Land Cruiser looked a lot like a jeep.
It sounds like your timing has slipped.
This seems to be pretty unsafe. I wouldn't try doing anything like this while the power is on.
The issue here sounds like it's the master cylinder failing. It is not retaining pressure when the engine is running. The reason they feel fine when the engine is not running is because the failing master cylinder is not getting power, and in essence is being bypassed.
