Fuel system diagnostics
A little background first. '93 Super w/ 2.3 L 5 speed manual tranny. This truck has always been very reliable starting. Starts first time every time. Recently, I've had to bump the key 3 or 4 times to get it to run. It will start every time but will die immediately. 3rd of 4th attempt it will finally idle properly and run perfectly. Idle will be within spec, power will be normal, will easily rev to 5k when entering the freeway, etc. Turn it off and it will fail to start properly again. Changed fuel filter, no change. Have not checked fuel pressure at the rail as I don't have a fuel pressure gauge, but the fact that I don't have any issues while on the road doesn't seem like it would be a fuel pressure problem. Pulled the pump and did note a small separation in the filter bag at he fuel pump inlet. When the key is turned I can hear the pump run for 2-3 seconds. No CEL showing. Any and all suggestions are welcome. Is the in-tank mesh bag replaceable separately?
