I am new to this site but familiar with board etiquette (i hope)
I have a 94 K1500 with around 220k miles.
Truck is in good working order and mostly original. main mod being a flo master muffler.
The truck has always started first time, and run well with slight hesitation from idle and occasional hunting at a stop light.
Last few days the truck started stalling occasionally at full stop. This progressed to occasional stalling on overrun.
Today the truck stalled at a traffic light and would not restart again. The engine turns over but makes no attempt to start.
checked obvious fuses etc. Checked TBI for fuel and it appeared very dry. After around 30 mins and with a friend turning the key, I watched down the throttle body as the engine turned over. Nothing, no sign of fuel. Then suddenly fuel and it started.
Replaced the air filter and headed for home. 5 miles or so later engine stalls on overrun.
Same process followed again, air filter off check for fuel, nothing.
Off to Nappa to get a fuel filter. On return, try starting, fires straight up.
I now have the truck at home and must start the process of locating the fault.
Have searched for threads with similar issues and there seem to be many but non describe the full symptoms I have.
The oil level is good, not sure about the sensor.
Fuel filter although old was also clear and not apparently the issue.
I dont have a pressure guage, but fuel is present at the filter.
The problem is hard to duplicate as the engine runs fine until it doesnt.
Any ideas of what to eliminate first or maybe the best way to diagnose?
Thanks in advance
