Tried cap on fuel line and had pressure,also tried red button in trunk.it was down,what else can I try
So you think you have fuel-so all you need is spark,compression and timing-so pull a plug wire off the coil pack and use a test light to see if you have spark-ground clip to engine,hold probe over open hole where wire goes and have someone crank motor-there should be a strong blue spark- denny

This sounds strange to happen after a service is done on another area of the vehicle. I would look at damage done by the hoist mechanism.
The hoists have lifting arms which meet the frame of your car. You have wires for the O2 sensors which can hang low. The fuel lines follow the frame and possibly could be crushed.
Vibrations. Air wrenches make vibrations which theoretically could shatter delicate electronic components. If you have sediment in the tank, this is also a concern, Some Ford products use a tank filter which can disinegrate and clog the fuel pump.
Get a pressure reading from the test port of the fuel rail. It will tell you if the problem is there.
