Hello Again! I've got an 89 ford f350 7.3 idi. I can get it started just fine. Unfortunately, after I leave the house in a couple blocks to a mile, the fuel filter light comes on, it sputters and dies. I then have to crank several times and it has trouble starting. I have to keep the starter going for a few seconds once the engine starts to turn over or it will die again. I can idle all day long, but when I hit the accelerator and get the tach up to 1500 to 2500 rpm's, she acts like she's not getting enough fuel, the engine stalls and dies within minutes of the higher rpm's. BTW, this behavior is recent. Here is what I have done... 1. replaced all the fuel injector return lines, hose clamps, injector caps and seals under the caps. 2. Replaced the fuel filter with a fuel filter/water separator from carquest. 3. Replaced the mechanical fuel pump with NAPA mechanical fuel pump. 4. Replaced the fuel tank sending unit 1.5 years ago so I don't think it's related to that. 5. Replaced the fuel tank selector valve 1.75 years ago so I don't think it's related to that either. 6. Changed my oil 30 miles ago. Dipstick reads full, but not over full. 7. I'm not leaking fuel around the injectors or injector caps or hose/cap connection. 8. Replaced the vacuum pump 3 months ago. I have a dual tank setup, but have been unable to use the rear tank since I got the truck 2 years ago. Therefore, I can't switch tanks to see if she reacts differently. Thoughts?
