Problems With fuel System

I have a 2001 Chevy Blazer. They day i test drove it i brought it up hills romped on the gas i went like it was brand new. The day i bought it it died on me 20 miles after driving it. Very Frustrating! Any ways it died on the highway just bogged out and stalled. I had it towed. I came home and jumped it and ran for about 2 minutes and died again. It lacked power would not responded to me giving it more gas. Once it was back at my house it would not start. I bought a new battery and altinator. Still would not start and i had to put fuel starter in the intake to get it to start up. But it doesnt last long. When I turn the key on i can hear the fuel pump go and the fuel filter looks new. I put knew spark plugs and wires on today. And the air filter was flithy.

Please help. I was told to look at the fuel injectors, spider gear and fuel pressure regulator. However i do not know how to check these or where to locate them. If you can help at all that would be great.

Thanks Bill

If you don't know these parts it will be really difficult to help you.You said the fuel system looks good so look at your spark output.pull off a spark plug wire, slide a Phillips screwdriver into were you would normally connect the spark plug. holding the screwdriver by the handle ONLY, place the screwdriver an inch away from the engine(metal part)have a friend turn over the engine.Be careful,don't be anywhere near the fan or anything that spins while the engine is turned over.Now check for spark between the screwdriver and the body of the engine.do you have spark?is the spark real weak?might be the ignition coil.Check your pressure output at the fuel rail too.

Go to the autozone website at autozone.com and register your vehicle. It's free and you will have access to an online repair manual for your vehicle. It should have the info that you are looking for. Hope this helped and best wishes. (I would suspect the pressure regulator)

If you have the spider fuel system, it is noted for problems. I have seen bulletin about poppets sticking causing a problem with cold starts. After you get it started, if may do fine the rest of the day. The fix was cleaning the poppet valves. The cleaning procedure was a shop procedure, they use the cleaning mixture under pressure.
I doubt if using fuel injector cleaner in the gas tank will help. Just my opinion.

Most likely a fuel pump issue. or leaking injectors. Try cycling the key on and off several times to prime the system before cranking. If it starts easier then this test will point to the above mentioned items.

If it was diagnosed as being fuel related, then it could be the fuel pressure regulator. The fuel pressure valve may be stuck open (sometimes). The gas will drain back to the gas tank and not maintain fuel pressure.
If you had trouble starting it first thing in the morning after sitting overnight, then it should have been diagnosed as the regulator (or valve that it controls).

Check it, but before you change it out, try a bottle of "Complete Fuel System Cleaner" ($8 AutoZone). It may clear it up in a couple of days' use. Oh, use a name brand cleaner, not store brand.

97 Blazer low fuel pressure and stalls in gear


If you have the spider fuel system, fuel pressure, key on engine off, 60--66 psi. After it starts it will run with less pressure. Are you using quality brand new fuel pumps?
This fuel system is noted for problems, including the fuel poppets.

Chevy Blazer won't start; fuel pump needs replacing


Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.

HELP! HELP! SOMEONE PLEASE ! 2001 chevy blazer fuel problems


I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.
