2002 Blazer LS Stalled out...turns over but will not start

I think I have a fuel pump issue. It was replaced in March 2009 but I think its bad already. I was driving and the car stalled at a light and would not start again. Today I tried to see if I could hear the pump when I turned the key but I didn't. I got under the truck wiggled some of the fuel lines and the wires to the pump and then I heard the pump begin to "buzz". The truck started but stalled after 5 minutes and the pump stopped making any noise once again.

Do you think I have a fuel pump issue or a connection issue? Should I replace the pump again with a new one? Is the job pretty easy to do myself? I have some mechanical knowledge. What tools are necessary other than what is needed to drop the fuel tank?

Thanks for any assistance.

You probably have wire problems seeing that when you wiggled the connector the pump starts to run. There are no extra tools required.Check the wiring for power to the pump with a test light. Power should be present for 5 secs. with key on. Power should be present when cranking engine.

97 chevy blazer w/ 4.3 won't start unless i pour full directly into it....what is causing this. was driving and it just stalled ...fires but won't turn over completely


if you can put fuel in throttle body and it runs. then it is not getting any fuel. check your fuel pump fuse and the relay, if ok, then you may have a bad fuel pump or a plugged up fuel filter. check filter and fuses first. good-day !!

Where is the ground or grounds on the harness that


I doubt you have a fuel issue if you replaced the pump. Try this to bypass the fuel pump. Spray some quick start or brakle cleaner into the throttle body. If the car still does not start then the problem is ignition related, NOT fuel related. If it does start then go to mitcell1diy online , search. You can get all the diagnoses info there.

I have a 2002 chevy blazer LS with a 4.3 Vortech motor..I recently replaced the fuel pump and added a new battery.All the electricals now work fine,but when i go to turn the truck over-nothing.Not even so...


Remove the fuel pump relay and replace it with another relay from a nonessential slot (i.e. wiper relay). Just make sure they are the same first. This will determine if the relay is the issue.

2002 lincoln ls died while driving it now it will not start .


I'm having a similar problem with my ford. By the sounds of it you have a fuel delivery problem, either clogged fuel filter or bad fuel pump (there are other issues that can cause this problem). Steps will have to be taken to try and narrow the problem down. i.e. check for spark, fuel pressure. Have someone turn the key over while you listen near the tank, if you hear a whining or similar noise this usually means your fuel pump is working.

What's the difference between fuel pump & replacement fuel pump


I dont think you have a fuel pump problem, It sounds to me like you have an alternator problem. You see when your alternator quits working the car will run on your battery juice untill it is out of juice and all electrical will go out when you put a new battery on it it will start working again untill the new battery is out of juice or untill the alternator is replaced. If the vehicle wont run then the fuel pump might have went bad too. I hope that helps you out.

2000 chevy blazer stalled and won't start back up


I would say the car is not getting any fuel. you could try replacing the fuel filter which is cheap. It could also be the fuel pump which is probably in the tank.(try tapping the gas tank with a hammer lightly) If the car starts then it is probably the pump. The last thing i think it could be is that is isn't getting any spark. Take the spark plug wire off the plug itself and put a screwdriver in the hole and make sure it is touching the metal part of the plug. Have someone try to start the car and hold the screwdriver near a piece of metal, if you see a blue spark then the car is getting spark, if you see nothing then you probably have a bad coil.
