No crank no start issue

Hello, I'm Danny.

Just a quick question first. When trying to start does the starter motor engage and spin the engine over and crank or does the engine not spin over and do nothing? If it is not spinning over I think you have a starter motor issue. Here are a few no start tutorials and how to test a relay:

I've attached a picture of the starter motor relay location and how to change the starter motor. Let us know what you find and we'll go from there. Hope this helps and thanks for using 2CarPros.

Hello again.

There are 2 things we need to check for. We need to see if you are getting spark and fuel. If you can remove a spark plug let's see if you are getting spark. Here is a tutorial showing what is involved:

You mentioned you replaced the fuel pump but I'd like you to perform a fuel pressure test to verify the fuel pressure. Here is a tutorial showing how to test fuel pressure:

The fuel pressure for your truck should be 38 PSI with engine idling or 47-50 PSI with engine idling with vacuum port on the fuel regulator disconnected. If you want to try spraying starter fluid into the throttle body and the truck starts that is an indication it's a fuel related problem. Let us know what you find and we'll go from there. Hope this helps and thanks again for using 2CarPros.
