    The gasoline may have destroyed the seals in the injector pump. I would sue the station. Basically everything in the system will have to be inspected and tested from end to end. Some of these components do not respond well at all to gasoline.

    Change your fuel filter and test for pressure at the injectors is where i would start, then test the glow plugs. (shaking head) like I said, basically everything will have to be tested and proved out.

This is NOT good! You can try bleeding the fuel system first. More than likely, air is trapped in the fuel lines, injector, and injector lines. Bleed at the fuel pump, (On the fuel pump to injector pump side), then the injector pump, then each line.

(You have to loosen the fitting to each line to each part, then when the air is bled out, and fuel comes through steadily, close it)

I also suggest an attorney to resolve the problem, as there may be damage. Pistons could have holes in them. Do a compression check.

Usually diesel's have 16:1 ratio compression. Today's gasoline engines have anywhere from 8:1, to 8.5:1, to maybe 9.0:1, (Maybe)

I'm willing to bet though, that you just have air in the system, and it needs to be fully bled out.
There is NO half stepping on this!
You have to start at the source, loosen each fitting, bleed the air out, and continue on down the line.

You need to have someone with a scantool check the sensors. I've had coolant temp sensors read -43F which tells the computer to dump more gas essentially flooding the engine.

Ford f250 superduty turbo diesel 7.3L Will not crank

Charge the batteries. take a Reading to make sure that you are getting almost 14v to both batteries. If it is not charging then take the alternator back off and have them check it. you might have bought a bad one. There is a way to test the glow plus with out taking them out. ( Take a piece of wire long enough to reach all the glow plugs from the battery. unplug the glow plug wire.If you touch the end of the glow plug with the hot wire it should make a little spark. if no spark then the glow plug is bad. do this to each one, but one at a time)
