93 inline 6 cyl. f150
 

I have a 1993 f150, srtaight 6 cyl. 300, with manual 5 speed trans.
I'm hoping someone can help me out with a problem concerning the truck not starting. The truck has a little over 200k miles on the odometer, and ran just fine until I started it, then drove it 4 blocks to the gas staion, shut off the ignition, and when I went to start it back up when leaving the gas staion, it wouldnt start. The engine turns over very strong, and at times even pops like it's going to fire, but it dosent. I replaced the fuel filter, and checked for spark. I have spark.

I have no way to perform a fuel pressure check at the moment . Can anyone help?

Thanks very much
