Question about Cars & Trucks
As a follow up to previous question... the mechanic installed the new fuel pump and the gas gauge started working, when truck cut off and/or will not start, same mechanic did something under the car and the gas gauge no longer works, but truck started and did not cut off any that day. But that night, truck would not start again.
Most cars have a strainer before the pump inlet and a inline external fuel filter. some have the filter and pump as one unit installed in the tank. the fuel gauge and float are attached to this unit . it is possible that the pump relay may be on the way out.

buy a can of carburator cleaner, spray into duct area while cranking engine. Does engine try to start(fire)? If so, find inertia switch (button in trunk). 'reset button just by pushing it. If this switch was triped, fuel injectors or fuel pump will not operaate. If spraying carb cleaner does not help starting then fuel pressure should be checked to rule out fuel delevery problem. AS a precaution, make sure your useing the correct key(original). Security problems also shut off fuel.

to make sure the fuel pump is operating get in a quite place get in vehicle and turn ignition switch on position you should hear alittle buzz for about 2 seconds try this several times if no buzz is heard then the fuel pump is not running. check fuel pump relay in power box by switching relay with one of same type thare should be one of same type in the box if not then purchase one and try it. If the pump is ok then you know you have a firing problem. check to see if you have spark by taking one of the spark plugs out then hook spark plug wire to it lay it on engine and look for spark while someone turns the ignition switch as if trying to start car

It does seem to be a fuel problem, If your engine is fuel injected the fuel pump is in the gas tank. As far as the ground it is grounded through its harness and mounting.. First thing I would do is put a fuel gauge on the fuel rail fitting and check fuel pressures. Pump wil run for a few seconds when the key is turn ON., and then stop ( assuming its working ) A lack of pressure willindicate an inop pump, or even possibly a clog in the fuel filter. Let me know.

probaly a fuel pump its common for vehicles to do that the best thing to do next is a fuel pressure check to verifiy its the pump
