Question about 1991 Toyota Corolla
What country, ? and what engine option? ????????????
the pump may not have 12v power until cranked, is engine dead/?
post the systoms so we can understand the context ....
or just curious.
alldata.com has the drawings.
here, ill look for you. USA, and take wild guess on engine.
ok, the toy has a test port conn.
key on, check pressure after.....doing....
Using a jumper wire, short both terminals of the fuel pump check connector. The check connector is located near the air cleaner. Connect the terminals labeled FP and +B.
reasons for pump failure.
i just check pressure cranking, (rubbers meets rode, logic)
if fail, to have 12v at pump i work backwards.
if 12v at pump, then pump is dead if pump is dead.
simple logic, here, and 100% effective.....!
toy spec on pressure is.
The fuel pressure should read 38-44 psi (265-304 kPa).
and running. with MPI engine the pressure will drop 10psi
due to vacuum reg. rules.......etc....
