Does it start with starter fluid?
So its not getting spark

ok maybe air flow issue
wont start with air filter on or off
reviewing your system now. let me know if you see a security light on.

just checked no security light
ok thanks and you do hear fuel pump run for a couple of second when you turn the key to on right?

This is going to be between the map sensor and the idle air control, and Intake manifold air temperature sensor you will need to get it on a scanner to compare operation wave patterns with known good ones already programmed into scanners data. I would say its the map sensor but dont want you to throw parts at with out testing.
where is the map sensor?
the map sesor is on the left hand side of throotlen
we have a good parts truck and replaced the entire throttle body with no luck
sensors and all
yes the part that bolts to the intake
and idle air control?
where is that?
on the right hand side of throttle body
2 vacuum lines coming off it?
no it has a connection coming off of it.
that was replaced also, throttle body has 3 sensors, 1 front, one side and one back. All replaced
just a electrical one
the front is throttle position sensor.
after all this you may have a bad ground topcm or a bad pcm.
any way to test the pcm?
its air fuel and spark and if all those are ok its wiring or pcm
you will have to test function from a scanner on vehicle.
wheres the ground to check
we had the computer on passenger side checked and its good whats the pcm?
your is grounded to the right fender
That would be it. I believe you need to get a full work up on your system you will have to have a scanner to perform this. I will have to guide you toward a half our scan at dealer. You dont want to through any more parts at it.
You can follow up with me even after accept. If you have any more question let me know. I know you have a tough issue with your truck but with todays computers on vehicles you need a computer to read the system.
