I would make sure that the pump is running all the time. Is it getting current?Try a jumper wire to the pump; Splice it into the positive lead .There are two wires at least to it and a separate for the gauge. I went through this whole thing to find out I had a frayed wire near the pump. I hope this helps you. Mark
try the pump on the frame there are 2 pumps high & low low is in tank
Also check the interia switch. It may need reset. It is located on the passenger floor board, under the carpet next to the tranny hump.
The fuel injector pressure regulator is located in the injector fuel pump. Most pressure regulators cannot be separated from the fuel injector pump.
No. Fuel pressure at the injector is regulated by the fuel pressure regulator.
the pressure we set for the injector and tested on machine
You may not have sufficient fuel pressure. The 2.2 should have 41 to 47 psi and the 4.3 should have 60 to 66 psi.
MIght be the injector itself.
probably a bad injector, check for pulse to the unit before replacing, could be another component if there is no pulse to the unit.
The 2000 GMC fuel pressure regulator is located behind the injector fuel pump. The injector fuel pump and the fuel pressure regulator will be on the top of the engine.
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
The injector is probably clogged, or there isn't enough pressure from the fuel pump in the first place.
The detergent injector ratio for a Sears pressure washer varies, according to the type of brand. The ratio of some pressure washers is 12 to 1 while others are 7 to 1.
You'll notice a drop-off in your gas mileage, then a really rough idle. If the pressure is REALLY low, you may even get a stall when coming to a stop occasionally. Replacing the fuel pump ranks up there with getting a prostate exam. So, before taking on that challenge, consider replacing the fuel filter, running through a tank of GOOD fuel-injector cleaner, and attend church (yeah, replacing the pump is THAT bad!!!). Good luck!
Pressure washers use an attachment called a chemical injector to siphon soap into the water stream. The chemical injector works based on the the physics principle known as the Venturi Effect. The Venturi Effect occurs when there is a restriction in a medium through which water or air is flowing. This restriction causes an increase of speed in the flow, but a drop in pressure. A chemical injector uses this drop in pressure to siphon chemicals or soap into the water stream. With a chemical injector, this drop in pressure is achieved by using a nozzle with a large opening. There are two main types of chemical injectors:Downstream injector- This type of chemical injector is placed on the outlet side of the pump. A special nozzle is used (as mentioned above) to decrease the pressure to that the chemical can be siphoned.Upstream injector- This type of chemical injector is placed on the inlet side of the pump to inject the chemical into the water before it enters the pump. This type of injector is also known as a "high pressure" injector because the chemical is pumped through the pressure washer, and is thus released at the high pressures with the water. This is the only type of chemical injector that you can use different nozzles with. Since the chemical is injected using the low pressure inlet hose (garden hose), you do not need a special nozzle to decrease the pressure on the outlet side. This type of chemical injector is usually not recommended, however, due to the fact that the chemical is circulated through the pump. This can cause seals, such as the pump's o-rings, to wear out faster.
attached to the fuel injector fuel rail which is attached to the top part of the fuel injector.
"Ford ICP" stands for "injector control pressure"
Do a fuel pressure test
The 2000 GMC Yukon Denali fuel pressure regulator is located on the back of the fuel injector pump. The fuel injector pump is located on the top of the engine.
Remove pressure from the fuel system. Remove fuel lines and the rails. Get a fuel injector puller to avoid the risk of damaging the injector. Remove the old injector and replace it.
Gneiss, if the heat and pressure are sufficient.
Water pressure from a garden hose is sufficient.
The pressure regulator is defective or an injector is stuck open.
Glow plugs only make starting easier for diesels. If you put the vehicle in a warm location and let it sit overnight, it should start even without glow plugs if the engine isn't too cold. Make certain that you are getting fuel to the injector pump assembly. With someone cranking the engine, loosen the fuel inlet at the injector pump and see if you have any fuel pressure to the high-pressure injector pump. If not, check the filter and low pressure pump.
Check high pressure diesel regulator on common fuel injector rail. Cost me about 5,300 Rands (1000 cans of beer/low end laptop compute price equivalent to diagnose and replace) in July 2009.
