I have a 2002 Cadillac Deville. I changed the fuel pump,sparyed starting fluid into intake and it started right up and stayed on for maybe 3 seconds. So I guess my question is what else could it be?

Fuel Pump Relay
Fuel Filter
Electrical Issues to the injectors

Its definitely fuel related if it goes off starting fluid, your having a delivery issue.

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

SOURCE: Fuel problem 1998 cadillac deville

I read somewhere that the fuel pump is lubricated by the Gasoline.It warned to never run out of gas with these Cadillacs.It may need a new fuel filter now.

The junk may have collected in your fuel filter?

Someone posted they had there fuel pump quit after running out of gas 3 weeks later. Try disconnecting your battery for 10 minutes first to see if it is actually the Anti-theft system.

More likely it is the spark plugs and the engine is mis-firing... take them out and check them

The owner thinks he ran the car ut of fuel,it died suddenly while idling. Now with fuel in the tank and starting fluid sprayed into the intake it tries to run until the either runs out. If this is air in...

Sounds like he may have a fuel pump problem. Turn on the key and listen for the fuel pump 'buzz' for a few seconds. If it doesn't buzz or hum the fuel pump is more than likely bad.

My 1986 cadillac deville cranks over but wont start, what could it be?

it may be a bad fuelpump,try sparying starting fluid into throtlebody if it starts then its a fuel problem, you can also check for spark,pull a plug wire insert a screwdriver into connection of wire and place close to a ground then have someone crank engine and see if theres spark,if theres no spark it could be a ignition control module,the best thing to do is pin point the problem by seeing what itt doesnt have,fuel or spark,

Will not start already replaced fuel pump has spark

spray starter fluid into air intake and try to start it if it starts for a bit and dies you still arent getting fuel. Try changing fuel filter for starters. There are lots of things to check.

Engine turns off while driving but will start up immediately

The in-tank fuel pump has a filter "sock" at it's intake as you drive fuel is picked up along with debris by the pump's suction along with dirt. This cloggs the pump causing the engine to die. this ends the turbulation in the tank and, the debris falls back into the tank so your engine starts right back up.
replace your fuel pump sock filter
