I am the recent and proud owner of a 1989 f150 custom, 5.0L, EFI, 5 speed, 2wd.
It has been starting and running fine until the other day. I had hosed the engine comp down. It started fine and I drove to work. After work, I went to start. Rolls over great but won't fire up. I checked spark to the plugs and seems to be fine.
Any suggestions??

 

Pull the distributor cap and dry out any moisture there. If it still won't start, put a fuel pressure gauge on it.

 

Yep, what steve83 just said.

By the way steve, nice pics of your roll over. Doing the same thing with my 150 right now.
