Question about 2000 Cadillac Escalade

1 Answer

I have a cadallic escadale. It will turn over but wont start.

I have a 2000 v8 cadallic escalade. I ran out of gas the other day and put gas in it. I tried putting gas into the top of the engine to get it fired up. It drove for about 4 miles and now it wont start but the ignition will turn over. I changed the fuel pump and checked the pressure everything is good and still not working. Its like it has spark just not start and staying running. If i put gas in the top of the engine it will fire up but wont stay running. Did you have any ideas cause it would be greatly appreciated. I have 3 kids and it is about to be the forth of july and this is my only car. Thank You!

The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

Check and replace if necessary the fuel pump. When the car ran out of gas the fuel pump was not cooled enough and worked with air inside, then fails more and more often.

bleed the injector / fuel rail, a small valve that looks almost like a tire valvestem, turn the ignition from off to on a couple of times and use a small screwdriver to push down the valve
( make sure you are messing with the fuel system and not the AC!) also be aware that highly pressurized fuel may come out. the symptoms you describe are also that of a fuel pump going out.

2007 escalade ran fine to the gas station then wouldnt start


There is a possibility the fuel pump may need to be replaced. Occasionally a pump will fail when the cool fuel is introduced in a tank even though the vehicle ran to the station with no problem.
