Question about 1999 Oldsmobile Bravada

1 Answer

00 bravada won't start. New fuel pump a few months ago. Pump comes on but not enough fuel presure to start and run. Starts with starting fluid but seems to have some kind of blockage. Thinking it might have something to do with the security system.

97 mercury mountaineer. won't start


hi,

watch your oil pressure when cranking, you have to have some oil pressure to get the fuel system to start. you may have to find the hot wire at the relay and energize it to see if it is indeed the fuel pump going out. if its been sitting and its a 97 the fuel pump just might have went, you can also try hitting the gas tank from the outside in the middle to see if that works too. have a water hose or fire extinguisher around when your working on fuel system and leave one of your battery cable a little loose..

Ran out of gas 2003 pontic grand am now it wont start,


You have a fuel pump THAT HAS FAILED for the following reasons. When you run out of gas the tiny electric fuel pump inside the gas tank overheats and the bearings are damaged from lack of lubricantion, both cooling and lubrication of the fuel pump come from the gas it runs in. You may get away with running out of gas a few times but you have set a ticking time bomb off, the pump is damaged and will fail sooner than normal. When you buy a new pump it comes with this warning, DO NOT RUN THE YOUR NEW FUEL PUMP WITHOUT ENOUGH GAS IN THE TANK (ABOUT 4 GALLONS) TO COVER IT UP IN THE TANK OR THE WARRANTY IS VOIDED. THE WARRANTY IS ALSO VOIDED IF YOU DON'T REPLACE THE FUEL FILTER AND CAN PROVE IT WAS REPALCED.

Turns over and over can hear fuel pump come on will start with starting fluid and runs great but when shut off for a little while wont start again only with starting fluid


If the starting fluid works then you have a fuel pump or a fuel pump relay issue. The fuel pump relay allows the pump to come on for about 2 secs and prime the fuel system. Once the engine starts then the power to the fuel pump runs through the oil pressure circuit.
If the car starts on starting fluid and then continues to run... I would lean toward a fuel pump relay issue. Hope this helps, Good Luck!

Won't start. New battery. Turns over but won't start.


These trucks are known for fuelpump problems. the first thing to check is to see if its got fuel pressure, try sparying starting fluid into throtlbody and see if it starts and runs for a few seconds, if it starts then you will know its a fuel problem, it will die out once the starting fluid is burnt up but at least it will tell you its a fuel problem and if it does start i would bet its the pump. good day.

Engine is turning over getting spark but will not run checked the presure release for the fuel line and nothing will come out


Looks like your problem is fuel related. A quick test is to spray starting fluid in it . If it starts and goes dead it is fuel related. Check your fuel pump relay and fuse.If it checks out good replace the fuel pump

I PUT A NEW FUEL PUMP ON A 2000 BRAVADA AND IT FIXED THE PROBLEM FOR A FEW DAYS.WHILE GOING DOWN THE ROAD THE ENGINE DIES.WHEN YOU TURN THE KEY YOU CAN HEAR THE PUMP RUNNING FOR AWHILE.HAS SPARK.WILL RUN...


Check all the fuel lines and connections very carefully for leaks and condition. The pump may be drawing some air.

We assume you have the correct fuel pump for the vehicle, that it is operating normally, you have the correct fuel filter and that there are no obstructions in the fuel system as a result of the work carried out so far.

Aftermarket fuel pump failure? Try "thepartsladi" store on eBay for low price GM OEM parts. Could also be wiring harness to fuel pump.

My 1997 chevy tahoe will not start without starting fluid. I hear the fuel pump running and have changed the fuel pressure regulator already and the fuel filter. The pump is only a year old. Have checked...


IVE HAD PLENTY OF THESE GO OUT EVEN A MONTH LATER. AS FAR AS THE STARTING FLUID JUST TRY AND CYCLE KEY BUT KEEP IT FROM TURNING STATER OVER. TURN ON AND OFF ABOUT 3 TO 5 TIMES IT SHOULD BUILD ENOUGH PRESSURE TO START. TO START MINIMUN PRESS IS 55PSI.
