Water in the car

How does anyone manage to fill the gas tank with water?

Who did all this work? Why didn't they leave the vehicle in running order?

Possibly needs the security system resetting after the battery was disconnected?

Turn the key back to the "Run" position. The security light will start to flash off and on. Keep the key in the "Run" position until the security light stops flashing. This usually takes 10 to 15 minutes.

Jeff, you or somebody else will have to hook up a external oil pressure Gage and verify oil pressure OK, before you have a catastrophic engine failure.

oil pump fuel pump, water pump, in what vehicle

This vehicle does NOT have a fuel intertia cutoff switch like Ford vehicles. As a safety shutoff, it uses the oil pressure switch. If the engine stops and loses oil pressure, the oilpressure switch cuts off the fuel pump power. There is NO reset on this vehicle

What does changing the oil,changing filters etc,have to do with the vehicle not starting?
What actual testing was done on --battery,alt,starter.fuel pump,etc.,how was this testing conducted and what were the results?
No fluids are consumed, in any motor vehicle,
If you have to top off,you have a leak,repair it!!

Oil pressure switch is bad.

CHEVY DOESN'T USE A FUEL PUMP RESET/CUTOFF SWITCH, FORDS USE THIS FEATURE, ON A CHEVY IT IS DONE WITH THE OIL PRESSURE CUTOFF SWITCH, SO IF U LOOSE OIL PRESSURE THE FUEL PUMP CUTS OFF, THIS OIL PRESSURE FUEL PUMP CUTOFF SWITCH AND IT'S WIRING ARE NEAR THE OIL FUILTER UNDER THE TRUCK.

check the fuel pump cut off oil pressure switch and the wiring to it. the switch is located near the oil filter.

I think someone is pulling your leg, there is more chance of the pope going on holiday to the moon than there is any engine being fitted with a plastic oil pump and oil doesn't turn to varnish petrol/gasoline left for a very long times can (but not always) turn to a varnish like substance inside the fuel lines.
I restored old cars for a living for about twenty five years and I only ever saw fuel go like that once.
Whom ever told you that I think is a little confused, the fuel can sometimes go like varnish and fuel pumps do have plastic parts, but the chance of the plastic degrading and falling apart is nil to zero and the only thing the fuel might do is clog the pump.
Being a Mazda the actual manufacturer hasn't been in business long enough for one of their very first cars to be reaching a point where the fuel would have degraded.
