after checking for plug cat. convertor, I tried starting fluid in the in air intake and got it to start. I drove it to Auto Zone to read codes but their computer didn't read chevy trucks they said after plugging it in. It turned off the engine light so Oreilly's couldn't read anything. when I got home it died again and couldn't get it to start again. That's when I changed plugs, wires and crankshaft sensor. starting fluid does nothing.

Hello, my name is Bobby. Thank you for the question. Is the truck still showing spark? Is the check engine light coming on when the key is turned on? Does the security light come on when cranking the engine?
