Hi, my name is ***** ***** is usually caused by a bad check valve in the fuel pump, this valve allows it to hold pressure in the lines when it is not running, when it goes bad, it allows the fuel to drain back into the tank,thus cusing the hard start, have you put a fuel gauge on it and seeing if the fuel pressure drops after sitting awhile?

Im.back sorry
Toyota Mechanic: Tim Mohr, ASE MASTER TECH replied 1 year ago

ok, you need to install a pressure gauge on it and start it up, and let it build pressure, then turn it off for awhile and see if it holds pressure, if it goes to zero, then the check valve in the pump is bad, and the pump will need to be replaced,Tim
