1991 Ford F150 Engine Turns Over But Does Not Start

I started my truck and put it in gear and smoke started to come out of the dash and the truck shut off by itself. We removed the entire dash and we did not see any type of charrred wires. We tried to start it again and usually you hear the fuel pump kick on but it doesnt now. we check to see if there was voltage going to the coil pack and everything else and it had voltage.

Can I put a 1981 ford f-150 motor in a 1991 ford f-150 truck

Sounds to me like you opened a can of worms that you are not equipped/qualified to deal with. To begin with, doing an engine change the way you did it is illegal. It is OK to put the newer motor in the older vehicle, but it is against federal law to put the older engine into the newer vehicle. REFERENCE: EPA ENGINE SWAP FACT SHEET

With all that said, if you want to do a swap like that, it is necessary to also swap wiring harnesses and computer modules (among several other components) if you expect it to work.

right either a bad earth cable from neg on battery to engine block or a faulty starter motor where the the windings have cooked and overheated thereby causing a short and a slow turn over check the earth cable to the engine first as this is often faulty due to corrosion on the engine end

Hit a bump, truck immediately shut off

If it still turns over but no start, I'd check inertia switch, usually located under dash on firewall near brake pedal, or on opposite side of hump in floor on passenger side, or under kick panel cover on passenger side by right foot. Will have a button to push & reset sticking out of it.

1991 F150 Interior dash and brake lights not working

you need to change out the 7.5amp fuse in the fuse panel under the dash. make sure you look up because i missed it the first time i had the same problem. the trim makes it hard to see when you have the cover off of the fuse panel.Or you have a short in your wiring or a short to power of an other curcuit. do you know what the code is for the check engine light? what engine is in it?

Sounds as if you are running extremely lean.Has EGR been bypassed maybe?
What is fuel pressure,on that vehicle the fuel pressure regulator may be adjustable.Some of these had an allen screw inside the vacuum port where you could richen the mixture some.Also try backing down on the timing a few degrees.
