All,
Approximately a year ago I had a turn key "refurbished" 7.3 IDI put in my 93 F350 after the original engine threw a rod. Since then I have put roughly 13,000 miles on the new engine. I have had multiple issues arise over the course of those miles, namely a failed thermostat, idler pulley bearing, and here recently what from viewing forum posts is a failing/failed lift pump.
A few days ago the fuel filter light began blinking when engine was at idle. Light would go out on excelleration/driving rpms. I drained fuel filter to see if this was the issue....light went out and did not flicker again for about 20 miles. Changed filter...light went out for about 30 miles. Truck then sat over course of a workday. On the way home from work the filter light came on...this time no flicker but solid after 1 mile. Truck would not hold idle at a stop light, and completely died. Let truck sit for a few minutes and cranked right up. Light began flickering again when not under acceleration/driving above 1500 rpm. Truck made it another 15 or so miles to where I parked it.
Do you all think this is a fuel pump issue? I have read through many posts...and have not seen a close similar situation like this. Any advice, as I am trying to determine what course of action to take.
