Sputtering and stalling. Fuel system problems? 98 GMC Sierra 1500 5.0 V8
Truck started sputtering and stalling, but would run fine once it had been driven for a little while. Sometimes it would start normally, other times it would struggle. I replaced the fuel filter (because it was easy & cheap) and the fuel filter (because my fuel level gauge wasn't working) hoping that my problems would be solved. After getting new pump it the fuel level is now reading on my dash, but it struggled to start, idled poorly and sputtered going around the block. I'm going to pick up a fuel pressure gauge and double check the fuel lines, but I could really use some good advice. I have no mechanical experience out side of oil changes and dirt bike rebuilds
