You didn't say, so I'm assuming that this is an LP Vapor fueled Home Standby generator. The bottom line to these things is that if it sounds like a fuel problem it almost always is one.

1 - Check for leaky fuel supply plumbing.

2 - Check the fuel pressure at the input side of the demand regulator inside the generator, it needs to be something like 11 inches of water all the time. My Generac/Guardian training came with a nifty manometer just for this purpose. If you can't get a manometer your LP supplier should be able to come and make this measurement for you. If you aren't comfortable with adjusting the gas pressure you should call them anyway.

3 - Change the spark plugs. This isn't all that common a problem, but it's cheap compared to changing the demand regulator.

4 - Check/replace the demand regulator inside the generator. This part controls gas flow rate rather than gas pressure so if the diaphram in there gets sticky or leaky you can have fuel problems.

I have a 98 ford ranger that will not start. i can spray starting fluid in it and it will run untill that is burned up and the accelartion isnt very good kinda of sluggish

Start by replacing the fuel filter as it obviously isn't getting enough fuel or air so also replace the air filter if it hasn't been replaced for some time. Another possible cause is that the fuel pump may need replaced. The pump will be inside the fuel tank.

When first started black smoke comes out exhaust pipe,, what could this be

Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head. Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix. Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

Lancer not getting enough fuel and cutting out

It might be the fuel filter needs to be changed and it's cutting off flow. Other wise you'll have to look at the pump or injectors.

Getting fuel wont start

If you can, have the computer scanned for active codes. Always check for fuel and spark. with fuel injection it isnt enough to know that the pump is running you need over 35 psi, line pressure. Let us know.

My truck 99 ford ranger died while driving down the road

fuel filter usually dont cause it to die and not start back, thay usually cause rough running. see if your fuel pump is running by getting in and roll up all windows so as quite as possible then cycle the key from off to run and lisen for the pump to run for 2 to 3 seconds should be a faint buzz sound if no sound is heard then replace the fuel pump relay, if no help probably going to need fuel pump
