Hi i have a 1994 f150 with the 4.9 il 6.I have replaced rotor cap plugs and wires made sure timing is 10btdc and replace all the broken/vulcanized vacum lines i could find .i have replace the egr solenoid checked the egr replaced fuel filter, pump, and pressure regulator and checked voltage on the tps.if I ease into the gas pedal it will acelerate ok but if I try to get in to it if will chug out and die. I haven't been able to pull codes by either the paperclip method or with a tester all it will do is flash so rapidly I can't count it and go solid Please help

 

You should get 3 quick flashes when the engine run codes begin to indicate a 6 cylinder then the pass or trouble codes will follow. Make sure you refamiliarize yourself with the code reading procedure. They may seem quick if you are not familiar with the process.Check that the processor has a good ground and I would also pull off its cover just to make sure a capacitor hasn't bulged out.
Also, make sure you have 45-60 psi of fuel pressure. If you did actually adjust your timing, did you remove the SPOUT connector first ?

 

Yes I did remove the spout connector and it is like the check engine light has a seizure and goes solid I also bought a code reader but it didn't recognize the truck at all and where is the capacitor you are talking about

 

Check the processor's ground first. You will have to remove the processor and remove its cover to examine the elctrolytic capacitors.
