Here is the address to the International Full-Size Jeep Association website: http://www.ifsja.org/index.shtml Plenty of info, know how, etc.
No. Hurricanes start from a cluster of thunderstorms over warm water. As the air pressure drops at the center, circulation begins.
Please be more clear in your question as I have absolutly no idea what you are saying (10 handicap)
Connect a fuel pressure gauge to the injector fuel rail. Watch the fuel pressure when you start it. If the pressure drops off as the engine starts running bad, it's probably either the fuel pump or fuel filter.
Air pressure is highest when it is cool and dry. It is lowest when it warm and humid. In high pressure, the sky is clear and dry, while in low pressure, the sky is warm and muggy and humid, which is where hurricanes can start.
Fuel pressure should be around 40. If the injectors are not getting power it will not start. Start with a crank sensor first.
You should start with the lowest objective (10x) and work up to the highest or until the object is clear.
Hard starting is typically a sign of a bad fuel pressure regulator. If the car starts and runs fine after a few cycles of the key, that would be a good indicator of this problem. The regulator should hold pressure in the system, when they fail, the pressure drops and the fuel pump has to cycle when the car is cranked to build pressure back up. Replacing this part is a good place to start.
My jeep had the same issue, normally it was when it was in idle. We didn't do tests or anything but found that when we replaced the oil pressure sending unit, it fixed it. We Guessed that its the unit not the actually issue with the pressure...
A pressure switch would activate the compressor's motor starter. When the pressure drops below a set 'low' limit, the motor powering the compressor turns on, when the pressure reaches a set 'upper' limit, the unit turns off...How's that for "Straight Forward"?
Presuming this is on an early xj40, the brakes system operates at very high pressure as it also operates the self leveling suspension. Low pressure could be caused by faulty accumulator, esp if accompanied by ticking sound from start up as the pump tries to build pressure. It should clear by pressing the `clear` button on the computer, but will reappear if problem persists. Generally, not much to worry about but due to the safety critical nature i would seek a professional opinion immediately.
Possible blown head gasket. To determine if this is the problem: * Take the radiator cap off, place your hand over the cap (make SURE your hand is clear of the fan) and have an assistant try to start the van. You should NOT feel any form of pressure against your hand
If you add iodine to starch the start will turn to a dark color blue/blk because of the enzyne Amylase (in starch), so if it is non starch there will not be a reaction and it will be clear.
