Hi Susie, Turn on the head lights and get someone to observe them while trying to start. If they dim during trying to start, replace the battery. Regards John

Very possible. chk fuel pump circuit fuse as well as all the others. Good luck, -Ned-

sounds like the pump and i think on moust lexus and toyota pump is in the gas tank under your back seat

In order to fix the problem i would recommend doing a fuel pressure test to see if your fuel pump is supplying enough (if any) fuel to the cylinders. If you are getting the correct fuel pressure, i would recommend check to see if your getting a spark to all the plugs

LOOK UNDER THE HOOD. AND CHECK FUEL LINES FOR LEAKS. YOU PROBABLY HIT AGAINST FUEL LINES WHILE REPLACING THE WATER PUMP.YOU NEED TO FIX FAST.FUEL LEAKS IS DANGEROUS.

check your fuse box. you might have a blown fuse
