I have a 94 ford bronco 5.8, I replaced the fuel pump and shortly after i had problems starting it. I then replaced: coil, distributer cap, and rotor button. It fired up after the first try with new button but now im back to where i started...it cranks but its like its not getting fire and im wondering if anyone has had this problem and if so what was it? Do you think it could be the ignition module?

turn the key on . you should hear the fuel pump running if not the fuel pump can be bad or its not getting voltage. there are fuel rails under the hood they look like stainless steel tubes they have something that looks like a valve stem on a tire .take the cap off turn the key to the on position and push the stem fuel should shoot out . if not the fuel pump you just put in can be defective .i had this problem

when you replaced your dizzy cap do you replace the spark plugs too?
you may have a bad plug and not getting enough spark

Did you do a Self Check for Codes?

Take the main distributor cap wire, stick it to your tongue, fire it up, and see if you feel anything 
/emoticons/[email protected] 2x" width="20" height="20" /> J/K but a ***** driver in the same location as your tongue woulda been should produce a pretty spark. You can try spraying carb cleaner into the throttle body to see if it turns over which should give you a pointer as to whether it's the fuel system or not. Don't OD it though cuz you don't wanna flood the chambers, that sucks. The sound check on the fuel pump doesn't always tell you much as my fuel pump in the rear is very silent but works very well. Good Ford part!
Which fuel pump did you replace? I don't know if you only have one, which I think you do, but you might have two, one in tank, and one under your driver door. The driver door one rarely goes out and in all reality your fuel system may work just fine as long as the high pressure pump in the rear is working fine. Also, make sure you got at least 1/4 tank of gas because it has been seen over time, especiallly with stock gauges, where you fuel gauge will lie to you.
If it's beyond that, make sure you're getting spark to the plugs and you have good plugs llike Kitten said. You can test it in the dark, fire the truck up, or try, and see if you have a light show under the hood, which will identify a bad area. Had an issue where my friend's plugs rotted so we got stranded in the middle of the desert. Checked under the hood and we had a nice light show with all the wires lighting up everywhere. During the day we couldn't see it though so our rescuer didn't get the neat show we did, just the unexpected call to rescue us.
