My 95 Blazer will start just fine and after running for sometime she won't accept fuel and lose power under strain(like up hill). If she dies I just restart and she runs fine for awhile longer. I also believe that my fuel pump is singing way to loud. Like straining. Could this be a vent problem? It seems like once everything is heated up is when I have the problem. On cool days it just take longer for the problem to occur. I replaced the pump/filter and no gauage lights on the dash comes on. Nor does the check engine light come on and nothing ever shows up on the comptuer. I am lost for ideas and so are the mechs can you help? Zack

I was driving down the interstate when the blazer just seemed to loose its power. I would give it gas but then seemed to act like it was getting too much. It eventually came to a stop. When starting off again it was fine for a couple miles and then just shut off completely. It would start up, but if i gave it any gas would quit. I was able to drive it home after it cooled just thought maybe got to hot. But a few days later it would do it more frequently until now. It is just parked. We replaced the fuel pump, filter and relay but the new pump won't even work. Battery is completely dead so have to charge it up....the new pump won't work........could this be a defective pump or is there something else causing this?

He said..."Replace the pilot bearing in the back of the crankshaft every time you can see it" That statment definately applies to a in-tank electric fuel pump, wiring harness and screen.l. |

I had a mecanic install a fuel pump it lasted 1 month ,now the car dies but it will start for a short time if I pour gas down the intake , if I let the car set for 2-3 hrs it runs again for 30-50 miles, this was an aftermarket pump ,I have changed the relay under the hood on the drivers side

| My son has a 97 blazer that started to intermittantly die and fail to restart. The next morning, all would be fine. After 30 days, finally quit at the shop, they said to replace the fuel pump. All good for 60 days, then same problem over again. Once again, the shop said the pump was bad. Again,new fuel pump, all connections at the pump looked "like new", it ran a week, and now, the problem is back. Sometimes it will start and idle, but put it in gear (auto tranny), and it will die. Great car when it runs. Ideas? | |

Replace the fuel filter located on the driver's side frame. That is usually done routinely as part of a major tune up. When a in-tank fuel pump is replaced, the in-tank wiring harness and screen should also be replaced or the new fuel pump will fail just like the previous fuel pump and for the same reasons. The wiring harness is included with the better quality fuel pump kits. Otherwise you must by the harness and screen separately. Sometimes, the fuel tank must be cleaned inside or replaced. Has your Blazer ever run out of gas? Never run a Blazer fuel tank extremely low on fuel or run out of fuel. That unloads the fuel pump and it has been known to ruin them..
