Check the ground circut. Don't Quote me on this one but that circut may run through the oil pressure sensor. It is a sefety feature in case of a roll over. If the engine dies or looses oil pressure it kills the pump so it does not keep pouring fuel on what could already be a bad situation.

How do I change the fuel filter on my 2007 Kia Rondo

That's the sign of a bad check valve in the fuel pump, not a clogged fuel filter. Do a pressure leakdown test overnight. If pressure falls more than 5-10-psi, it's a bad check valve.

At the start of the engine, the fuel gauge reads empty. i know for sure the gas tank is filled up with a decent amount or its full. after afew miles, the gauge slowly moves to its proper reading. i know...

Most cars and truck nowdays show the tank empty when you start it. Then it slowly advances to the correct level of fuel in the tank. You can try and use some fuel additives like Gumout or Valvoline that clean the injectors and other fuel sytem parts. You can get a buildup of tarnish in these parts and this can cause slow readings. If this was the case it should improve after a few tank fulls of gas with the cleaners added. The guage could also slowly be going bad. The newer style guages are connected to the fuel pump and you will need to replace the whole unit if this goes out on you. Keep in mid that when the fuel pump quits, it quits, usually without much advance notice. If the car starts sputtering and does not have full power, this will hint at the fuel pump going bad. If your car has over 100,000 miles on it, you might want to think about preparing to change the fuel pump, these seem to want to go out shortly after 100,000 miles, but you can get lucky once in a while and it can last longer. Keeping your tank at least half full with clean gas is a big help, the gas keeps the fuel pump cool so it last longer!

2002 Dodge Ram Fuel Delivery Issue

a common problem with all dodge products from 95 or so to recently especially the trucks was running out of gas and the guage 8 times out of ten would read1/4 tank.
to check for this crank it then under hood locate the shradef valve on the fuel rail, remove the cap and depress the valve[like letting air out of a tire] if a spray of fuel comes out that part is ok. but if air or air and a little fuel come out put some gas in it and get a new fuel level sender
ps i am assuming its a gas engine

Trying to start 2001 dodge ram pu it cranks but will turn over

Stop cranking! It Sounds like you're nnot getting any fuel. No fuel + cranking equals a burnt out injection pump. Start by checking your lift pump pressure. This can be done at the fuel filter by removing one of the small test ports and hooking up a pressure guage. With the guage installed, bump the engine over which will cause the liftpump to kick on and run, giving you a reading. A good pump will read 10-12 psi. a bad one will read in the 3-5 range. Good Luck!

Escalade won't start

check the fuel pump. there is an access port on the fuel rail underneath the intake manifold cover. it looks like a valve for putting air in a tire. at your local car parts store you can find a fuel pressure guage to make sure your getting the 45lbs psi that is needed to run the fuel system. if your not getting 45psi when you crank the engine replace the fuel pump. it is located in the gas tank. ( FYI ) If you run below a 1/4 tank of fuel the fuel pump is no longer covered with gas, and over heats. thats why most of the gm pumps go bad. D
