lost my newest post,
is still dont know how many doors???? the car has,,, are only your car, the harness for 4doors are not same as 2doors, sorry. but
where was pressure tested, name the spot exactly please.?????
does the engine still have a CAT CON, Cat converter there?
nor do I know your ALTITUDE. (if near sea level say so , if in DENVER yah or Colorado springs, for sure.) in a sea port, say near sea....
do the FPR tests, got 60psi now. shunted. (hose pinched)
did you test pressure with fuel cap off, some are bad or wrong caps. (vacuum breaker missing or bad, this is 1min work )
pretend its 10. psi
new pump>?
I check pump voltage, , no not yet, on all Kicks vitaras an trackers for 3 generations, we check voltage first
6 volts is NO GOOD.
but has 2 causes. (bad pump ,bad wires) when i say wires are bad ,that means end to end, all wires this pair, and connections on that wire, its a conductor and must conduct with nill resistance.
This page covers them all.

see the harness drawing, marked 2doors loves.?
if 2 doors, that G402 screw, will be rusty , in 2016. kinda for sure. pump black ground loves to fail HERE, like clockwork.
now look at the harness drawing, see that?
see C403 on left side, behind tail lamp, the pink wire is pump power, if rusty its hopeless., here. one can measure the voltage at the pink wire
if 12vdc ok. if 6vd, measure current ,if volts 6v and amps 4amps, then find the bad connector.
if 6v and 10amps the pump is shorted and is bad.
if 12vdc is ok. then
see center bumper pump connector pair, 12vdc across them (means near battery voltage every time I say 12v.) 10v cranked, 14 running is par.
The pump needs 12vdc run right, its just a DC brush motor., and works like all DC motors.
the suzuki wiring is weak, it will go to a low voltage if the pump shorts one commutator segment and sucks 10 amps, and this causes the low gauge wire to drop voltage.
end to end,
on some side kicks the pump can even lower the voltage in the ECU and cause it to crash. (reboots, over and over)
the voltages matter big time here.
we use a simple ammeter, to measure this. 4amps.
4amps is spec, at 12v.
when we do fuel pressure we do a battery of tests,.
why because old cars can have many fails.
the pressure key, pressure running, the shut test.
the vacuum applied to FPR pressure tests, this test the FPR that love to fail this old so we never skip testing it after all the gauge is connected and takes me 5min to finish this one test.
the injector leak down test is last.
