After i did a complete tune up on this truck it is still chugging and the check engine lite wont shut off.
Spark plug wires are crossed, recheck firing order, if problem was there before you canged wires ecm is bad

cross the wire, probably the firing order problem.
Did you change the distributor cap, sometimes the distributor cap inside cracked, you won't see it, take off the distributor cap, but you have to remember the wires' order, lightly drop the distributor cap see if you can hear the cracking noise.
Or during the dark night, get a dark place, start your engine,see if there is spark out, fix that, maybe your car will run better.
When I had my Union 76 service station, I have solved several cases like thiat.
I had a big Sun electronic scope from 1973 to 1984, during that time, something I could't ping point where the problem was, therfore I used many experience, maybe I am wrong, but you can try it, I like to try everything.
Hope this ccan help you, good luck.

To determine what's wrong, u need to have the codes read. If the light is coming on, it is a signal that something is wrong w/ the emissions system. A code is stored in the cars computer that will indicate what the problem is. Most parts stores will read the stored engine codes for free. They plug a scan tool into a port under the dash to retrieve the code(s). Write them down, and ask what u should do to correct the problem. If u have any further questions after that, u can post them here. Let me know how u make out.

This could be a multitude of things but my first suggestion would be to change the spark plugs. They are cheap and can be bought at any auto parts store.

Drop in to autozone, or Pep boys and have it scanned, free, for trouble codes then go from there. Could be something simple & cheap
