Got a 1995 ford f 150 straight six started feeling sluggish then died on hwy had it towed home noticed thermostat was stuck on cold so I changed the thermostat an thermostat sensor worked fine for about twenty mins now it starts right up idles rough an low then eventually dies found that cylinders 2,4an 6 are not working I have changed the plugs wire rotor an cap nobody can tell me way three cylinders would all of asudden stop Workin can somebody please help

 

I would try a new coil, other than that no ideas

 

2, 4 and 6 injectors are batch fired together. Those cylinders probably aren't getting fuel.

 

Thanks For responding how can I tell if the injectors are not fuel? What does batch fired together mean? Sorry I am a license electrian not a mechanic thanks for understanding

 

Your six injectors are fired three at a time by the computer, they are fired in two batches of three. They have power with the key on and the computer gives the ground to fire them.

 

Thanks for that info is there anyway I can fix that or even tell if that is the problem thanks for taking the time if you even have an electrical problem just let me know

 

Pull some codes...sounds like the cpu is on the way out.

 

No, no it doesn't.

 

C'mon man, you said you're an electrical guy. Check for power and trigger ground. Unlike a house, there is no neutral.

 

Tryed pulling some and it keeps giving me 522 which is trans not in neutral but it is in neutral does the computer control the headlights cause had a problem with just my headlights cutting off while I was driving
