Truck will not start. Have replaced fuel pump, filter, spark plugs & wires. New starter, air filter.
Has a good battery in it. Checked all the fuel injectors and they are fine.

Before it would start but idle real rough. It would go down the road and it feels like its miss firing and stall.

I've been told something with the EGR..is it the valve maybe a sensor? Could it be an o2 sensor? Mass air flow?

Any input would be greatly appreciated. I'm stumped and have dumped to much money in it and its not fixing a thing lol.
 
Clean your MAF and see if that does any good, could be a number of things. Does it crank? Sputter but not run?
 
Yeah cleaned MAF with maf cleaner. It cranks starts for a second or two then stalls.

Thinking of replacing the Egr valve today. Only place around me that can do a diagnostics onit is the ford dealership but it can't make it there lol. So its just a guessing game for me.
 
What was the name of the fuel pump you put in? If its an Airtek they are no good. I run a shop and about 70% of those fuel pumps are bad.
