Engine Cranks But Does Not Start

Hello,

As you know you will need spark and fuel to start an engine (and compression).
First you need to make sure that you are getting spark to the plugs.
This can be done simply by removing a plug and cranking the engine.

If you have spark, then you need to make sure that fuel is getting to the engine.
Does the fuel pump come on when yo turn the key to the on position?
Typically, the fuel pump is audible when the key is at on position.
And inoperative fuel pump can be due to a bad fuel pump relay, faulty wiring or a bad pump.

Here is a helpful guide:

Let me know what you are experiencing.
Thank you.

That was actually the changeover hear for the Wrangler from carbureted to fuel injected.
If you have a carbureted engine, then the fuel pump is a mechanical pump and dot does not have relay or fuse.

The fuel pump is mounted to the front corner of the engine block and is actuated by the fuel pump lever contacting the camshaft.

I have attached the diagrams as well as the testing procedure for the pump.

Have you checked for spark?

I have attached a diagram below. It shows the firing order and which post on the distributor cap correlates to which cylinder. This will help you make sure the wires are correct.
Let me know how it goes.
