03 saturn view cranks but wont start


first of all, check the fuel pump relay to see if it is going bad. if it is ok! also try this, Have a person turn key to on,, and put your hand on bottom of fuel tank. if the pump is turning on, you will feel a vibration in tank. you may have to do this a few times. the pump only turns on for a few seconds to pressurize system, or to get fuel to the engine. just keep turning key on and off to recycle fuel pump. Good-Day! Hope this helps! relay for pump may be bad.< Check this first.

2005 cadillac escalade wont start


Check for fuel pressure at the fuel rail on the engine. If you have no fuel pressure, suspect a clogged fuel filter or faulty fuel pump.

Where do you drain gas in a 2008 Cadillac Escalade ESV


There is no drain for the gas tank. It either has to be syphoned out or pumped out by use of the fuel pump.

or delayed starting
if delayed spark -electrical problem -check Ignition module and wiring
if delayed starting (spark ok) i'd check is Fuel rest pressure And Fuel pump relay
Does fuel pump cycle when ignition is turned on
meaning engine starts when oil pressure activates pump

How many fuel filters are on a 2003 Cadillac Escalade esv ?


There is only one fuel filter on a 2003 Cadillac, If I remember correctly the fuel filter on my 03' was on the frame rail drivers side rear and it was pretty simple to replace. You do need a fuel filter fuel line quick release tool, common to by at any parts store with the fuel filter that should be replaced every 15,000 to 25,000 miles or once a year.

2002 monte carlo fuel gauge doesnt work,pump works ok.


It is likely the fuel level sending unit. I had a customer with an 03 Monte Carlo that the pump went out and the fuel gauge hadn't worked in about a year. We replaced the fuel pump module and it took care of both problems. I believe the sending unit is available separately from the complete module.

1979 chevy step van 350 new fuel pump rebuilt carburetor wont sta


remove the fuel line from the carb, put it into a bottle, crank the engine, If the bottle has fuel in it the fuel pump is working properly, if not, check the filter, and the fuel lines to the tank!!!
