Fuel Problem
I've got an 89 F150 4.9l with a problem. The truck will be running and then stall(Driving and idling) Through a series of checks I think I've determined it to be a fuel feed/ignition problem. I have replaced the in tank fuel pump, the filter, the fuel relay and plug, the ignition coil. I've checked for blockages in the fuel lines.
I'm lost! Can anyone help?

Step #1 (always): pull the codes.
Step #2: read the Haynes manual troubleshooting section (Ch. 0).
On your truck, the ignition module is mounted to the distributor, and those are known to fail, so test it. Haynes shows how.
