I'd suggest getting the vehicle...

You should have the vehicle scanned for codes (https://www.yourmechanic.com/article/what-is-the-on-board-diagnostics-obd-system) to see if you have codes to the camshaft or crankshaft sensors. Either of these may cause the no spark condition. If the fuel pump regulator is bad, then you would...
