Won't start
 

I have an 89 f150 4.9 6 cylinder. I just replaced the clutch and now it won't start. It turns over but won't fire. Fuel pump and spark plugs are new. Right before I did the clutch it started up and ran fine. Any suggestions?

Check your neutral saftey switch. I have forgot to check it when adjusting a clutch before and then no start.

ok so it will start and run for a second when I spray ether into the air intake. It only runs for a second or two then it dies. Any thoughts?

You tried you fuel pump reset button? Just a thought that you may have jarred the truck enough while you were working on it to trip it.
