Maybe low water or check your skimmer weir door and be sure it is free and not sticking in the up position.

What is next on trouble shooting fuel injectors?


what engine?

Do you have power to the injectors? if not check the ECM1 fuse. If blown check the wiring harness around the throttle body for pinched wires to the injectors. Really common on the early throttle body engines.

Where is the fuel sensor on a 1997 jeep grand cherokee


Have you checked the fuel filter? I would pull the fuel line apart before the filter to see if the pump is putting gas into the line. With key on, the pump should run for 2 seconds to pressurize the lines and fuel rail. And when the engine is cranking over, the pump should be running constant and putting gas into the line. If gas shoots out, possibly the filter is clogged or the fuel pressure regulator on the fuel rail is defective. If no gas comes out, possibly the pump filter sock is clogged or the pump is defective.
Very unusual for the pump to run and have NO fuel pressure.

Why still no fuel pressure


Are you checking fuel pressure at the engine fuel rail with a pressure gauge hooked up, and key on? And you still hear the pump turn on for 2 seconds with key in on position?
There should be pressure in the fuel rail then. If not, is it possible you put the new filter in backwards? I would take off the line going into the filter from the gas tank, and leave off for a test: you're right, the pump turns on for 2 seconds with key on to put pressure in the line and the fuel rail. But then when the engine is cranking, the pump is turned back on. To check if the pump is picking up fuel, have someone crank the engine over while you watch at the filter: gas should shoot out in a good stream. If it doesn't, check for a kinked line from filter to the tank. If the line is good, you will have to take the tank back off and see why the pump is not picking up fuel and sending it out.
Let me know what you find. If the pump shoots out gas at the filter area, but still no fuel pressure at the engine, check the line from the filter to the engine-may be kinked, blocked, or clogged.

I have a 7 hp B&G craftsman Pressure washer , if I place an air filter on it ,it wound't start or run , if I remove the air filter it would run like a champ, but after 10 mints , oil would shoot out...


First,

It sounds like the air filter is full of dirt preventing air from flowing through, starving the engine of air.

As for the oil shooting through, are you certain the oil is coming from teh carb?. Makes no sense the engine would run if it also shoots oil out the carb. There is nothing in the engine that would cause this, assuming it's a gasoline engine. And I am not sure a diesel would do this either.

Blow back out value cover and oil stick


your internal pressures are too high!!!!!!!

change the pcv valve and get the oil filter checked. Sometimes the oil filter will block and the oil pump will over pressurize the engine. See a mechanic Soon!!!

Locating the fuel filter


You didn't state the year or engine size,,,, On the firewall,( passenger side, back of engine compartment, it's round) on fuel injected models, relieve pressure of fuel line before beginning- gas cap off,also must release pressure on fuel injected models- some have pressure release on top of filter, others on fuel rail,this will be a bolt on top of a bolt. Hold the bottom bolt (w/ open end wrench, loosen top bolt w/ 6mm wrench. Cover with rag, so you don't have gas shooting up in your face. Carb models: have 2 filters, one inline in engine compartment, 2nd under car attached to fuel tank. Open gas cap to relieve pressure before starting removal on carb models. countrycurt0
