So I have been having this issue with starting my truck, it cranks, and I can smell fuel, it just wont fire over, it used to start after 3rd or 4th time, but now nothing, i replaced plugs, wires, distributor, and rotator, and still nothing before when i could get it started it would stay running and even restart even after sitting for an hour or 2, and ran great

 

The first thing I would do is check to see if I had good spark coming through the spark plug wires while cranking the engine over. There is still more to the ignition than what you replaced.

 

It has spark, I have seen the arch, I checked that on both ends of the wire, when I was able to get it started it stayed running, ran great, it only had trouble in the mornings, by the afternoon it would fire right up

 

Will the engine run briefly if you spray starting fluid in the air intake?

 

haven't tried that, i can smell fuel while im trying to start it

 

I would try the starting fluid test, it should run briefly unless the spark plugs are wet with gas. Then I would check the fuel pressure.

 

Sounds like a bad ECT or IAT/ACT sensor to me.
