Everything is spark plugs, distributor cap & wires, fuel injectors (did not replace fuel injector wire harness or connectors though) fuel pump& filter replaced 2 yrs ago by pep boys and gasket seals to oil case & manifold, cleaned throttle & new manifold sensor
I have heard about the cranck sensor coukd be the problem
SOURCE: Fuel injectors or Distributor Cap?
the blinking CEL light is an indication of a miss-fire, run the code retrival test to find out what cylinder is the one missing, at your miles it could be almost anything from a low compression issue to a bad distributor cap, a fuel injector could be the problem, run the test and get back to me, Kragen and other chain parts stores will test the system for codes for FREE!

That normally means that you have a issue with your gas cap try replacing your gas cap first then diconnect the negative terminal of the battery for about three minutes to clear the memory and start the truck again

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

Has anyone tried adjusting the fuel air mixture?
Based on what I am reading this is a gas engine and I am also assuming it is fuel injected. (Or does it have throttle body fuel injection?)
I suspect a case of dirty fuel injectors at the moment. They will need to be removed and cleaned.
If you have throttle body fuel injection then you will need the fuel air mixture adjusted.
If you respond can you let us know the "engine size" that is installed please. It would help us to help you in troubleshooting.
Thanks for using Fixya. Kelly.

Hello.. looks like you are getting good fuel delivery. Is the fuel curve mixture on the scanner in specs? How is the timing, the timing chains on these engines will stretch and throw the timing off causing a ping and missfire -- a weak valve spring is something to consider. Also, the PCM may be faulty. I hope this helps.
Camshaft Position Sensor Circuit Intermittent
Possible Causes:
.Wiring harness fault.5v supply circuit open or shorted to ground.Tone wheel/pulse ring is damaged or corroded.CMP Sensor has failed.CMP Sensor signal circuit is open, shorted to ground or battery. voltage or 5v supply.CMP Sensor ground circuit is open.PCM has failed.Trouble Code: P0016
Crankshaft/Camshaft Timing Misalignment
Possible Causes:
.Base engine problem (i.e., the camshaft timing is not correct).Intermittent condition.CKP or CMP Sensor signal is erratic (check with lab scope).Tone wheel or pulse wheel is damaged or contains debris.CKP or CMP Sensor, harness or connector has failed.PCM has failed.Trouble Code: P0061
Engine Temperature Control Level 2 RPM Performance
Possible Causes:
PCM need to be reprogrammed.PCM has failed.
The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the electronic system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.
