Hey, I know this is a Ranger site, but I'm sure a lot of you know a lot about Ford Trucks. The specs are a 92' F150 2wd, I-6 300 c.i., auto tranny. It has been old reliable with 220,000 on the ticker. Probably lower because the motor I guess was out of a 95.

Well the past week the girlfriend went to back it up and it stalled, which it normally does if you don't give it a little bit of gas right away. Well it died so I told her I would back it up, I went to restart it and white smoke came out from the drivers side corner of the dash, it still smells real bad. So someone on Greatlakes4x4.com told me to check the ignition switch, we got a brand new one, still the same problem. This is what it does:
Engine Cranks, just doesn't fire.
Before I had the dash ripped apart it had a check engine light, so we got a code reader and it just constantly beeped, so we thought it was the code reader, so we went and bought the same one, and it did the same thing!
Fuel pump will stay on as long as the key is in the run position, or if it doesn't turn on it turns on a long time after you turn the key on.
Fuel rail does have pressure as long as the fuel pump kicked on.
There is no spark whatsoever.
We checked all the fuses in the cab fuse box and checked all in the power distribution box as did we replace a few of the relays in the box.
There are no apparent burnt wires.

Someone give me some help please, its going on vacation sunday!
 
normally, the fuel pump should start 2 seconds then goes off when you turn the key to ON(engine off). First think i should check is the CPU. I don't know exactly where it is located but on my 89 full size Bronco the cpu was located behind the parking brake pedals on driver side kick panel. Just unscrew the cover and take a look at the board.....
