What I would do is check the fuel pump relay to see if that is good also check the fuse for the sending unit and if all this is good drop the gas tank and replace the fuel pump and here is a place that sells only GM parts

It could be the fuel pressure regulator, but that can be determined by testing the actual fuel pressure in the fuel feeder rail. But first, have you changed the fuel filter? The fuel filter usually is clogged with debris whenever a fuel pump fails, so be sure to change that first.

Maybe it's your fuel tank that has contaminants -use a pressure hose and blow back the fuel into the tank, remove the fuel tank and flush out - could be rust as well. Hope this helps...

Im suspecting a problem in the fuel pickup tube in the tank. Possible rusted and when you have the fuel run to the back of the tank the hole is exposed allowing the pump to pump air and you are in effect running out of fuel pressure.. Suggest you consider pulling the pickup unit and check .

2004 Blazer runs normal cold start, plenty of power. Bogs down after warm up, diminishing power, won't go. Catalytic Converter? What is temp sensitive could bog engine down?


The Catalytic Converter is one possibility, but not likely. If when the truck bogs down, and stalls out, this could be more related to a fuel pump issue. If on your truck the fuel pump is located inside of the fuel tank, then once the pump heats up, this would happen. Acting as though it's something electrical, but it's really not.

S10 blazer lacks power, bogs under acceleration


Check your coil output, buy a cheep spark tester. Pull of a spark plug wire and plug in the tester(ground the other end), set it to bridge a gap for 30,000 volts.Have someone start it and make sure the spark will jump the gap on the tester.Danger-Very high voltage! It will light you up if your touching the tester while the car is running!You'll be able to see a bright blue spark(and hear it as well) if your coil is good.If it's a yellow thin spark it's probably the coil.
If you have good spark, check the fuel filter and fuel pressure at the fuel rail.
Back firing could be timing,cam position or crank position sensor.Worst case scenario, timing chain or belt.

Just changed broken fuel line on 99 f350 7.3l and wont start now


You can try this, turn on ignition, you should hear a whirrling noise from the fuel pump, if you hear it, turn ignition off, wait a few seconds, turn it back on, do this 3 to 4 times, so the fuel pump can build up some pressure, then hold the pedal down about half way while your cranking the engine. If there isn't anything else wrong, it should start.

97 blazer fuel pump


Are you getting fuel to the fuel rail on the engine? Can you hear the pump running? Recheck the hose you replaced. Could have come off.
