Check that the Idle air controller is not faulty, disconnect it and start the truck again, if the truck starts (running poorly) then replace the IAC.

the best way to do this is to disconnect the fuel line from the top of the manifold, run a hose from the line to a gas canister, and turn on the key-the tank's fuel pump will empty the tank. best to have an assistant to operate the key while you monitor the filling procedure.

Hook up a fuel pressure gauge an see if you are not loosing fuel pressure causing this running problem. Hook it up to the fuel rail with a long enough hose to locate the gauge where you can watch it while you are driving. If you are loosing pressure then check for fuel resistance in the line, fuel pressure regulator or fuel pump going bad.

its easier to just replace the whole arm

it could be the distributor cap is not sitting correctly, lay a piece of sandpaper down on a flat surface and place the cap on top and rub it round a few times, this should help it seat better, only other thing i can think is the icm might have a crack in it and damp is getting in this will stop a spark being made. if it is you can clean the crack and fill with liquid bonding glue, dont matter what type just leave it to dry for 12 hours and keep filling with the glue till its spelled the crack, when dry it should work fine in all weather.

You may be having an intermittent failure with the fuel pressure regulator - checking the fuel pressure when the truck won't start may pinpoint this problem. If the pressure looks OK, this same problem can be caused by the ignition system as well (ignition coil or control module).

I saw what you replaced, didn't see any testing? What testing have you done? Make sure battery has a full charge?
When the problem is ongoing, have a helper crank it, while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Any applicable trouble codes?
If you have the spider fuel system, that system is noted for problems.

indicates that the arm has turned on the shaft
loosen off that arm
place the wipers in the parked position , reposition the arm correctly and re tighten it

A great place to start would be a tuneup. Plugs and wires, cap and rotor. If the check engine light is on, have the codes read. Places like Autozone and Advance auto parts will do this for you for free. Their hope is that you will buy parts from them.

The blower motor may be bad, it would have to be checked to determine so or not, it also has a fuse, relay and a resistor. If any one of them things fail it will not work, plus the switch that controls it too may be bad. All must be checked to determine which is bad in order to know what your problem is? I wish I could help you better!

On the master window switch control, if the windows work at the doors but not at the master switch, then I would say it is the master switch that is bad, but if you know how and have a volt meter, you can check it to determine if it is as well as all above.

Hope this helps.

Make sure plugs are gapped correctly and coil pack is good . If can't feel it missing could be a false code generated by computer . Hope this helps
