Question about 1988 Chevrolet C3500
Truck is starving for gas, fuel pump has been replaced, jets, and regulater. code is reading 44 O2 sensor (lean exhaust)
How do you know it's actually started for gas?
Are you sure it's actually starved for gas, and not just a bad o2 sensor? Are you having issues with it running properly?
When is it running lean? WOT, idle, always? It's possible you have bad diaphrams and your secondaries aren't opening up, but hard to say without an actual description of the problem.
