36-43 PSI, keyon, not started ( you may have to key on 3 times to build enough pressure, pump runs on 3 seconds) you told me 50, so is WRONG.
Running: 30-37 PSI , idling.
shunt tests, is 55psi, (return line pinched )
the full FPR vacuum test, is 21PSI (typical) (hand pumped to 26" inches vacuum (this checks the other end of FPR range, showing linearity is ok.
the leak down test is. that suzuki calls Residual :25 PSI , after 1min. drop test.(running then key off,how long does it hold) (finds injector or FPR leaks this)
the next test is fuel pressure, injector balance test, per the book, I have the book page links, for you.
at post 4 and 10 you had 50PSI , key on-no start , or with engine running pulled vacuum nipple on FPR and got 50psi, both those tests are wrong, (and really is same test,)
50 is wrong, I told you that it was wrong but you do not believe me,there is no communications errors,
key on pressure at 50 is 7 PSI too high, (that is a HUGE error 7)
did you remove the tank side GAS cap to see if that makes fuel pressure go good?
most these cars now have bad FPR, due to age, alone, endless posts here for it failing, some in horrible odd ways (sticking inside caused due to moving 1million times for 22 daily driven , these parts wear out, do you understand that?
the injectors can be clear by unltra sound, to get the impossible to clean screens clean at home, they reverse flow the injectors to do that

These injectors unpugged all read 10 ohms (about)
that means with 12vdc battery (it is) that 1.2 amps per coil or 1.5amps running,
do not hot wire the injector or they will burn up. power = amps times volts so 21 watts is dissipated, by the coil inside. 10 to 22 watts, not running or running. ok so do not burn up the injector hot wiring it, ok?
what a shop uses, as did the GM/suzuki book did clearly is use a device called an injector pulsers.
this acts just like your ECU and pulses injectors so that do not overheat, for above reasons, stated.
did you know all that?
its not too hard really with a helper at the KEY
so with the fuel fully charged key oh 3times,an at 41 pSI. (not 50, if 50 that is bad FPR)
we rail is charged as duane shows in its great video.
he then Pulses (tool) the 1st injector for until the pressures goes to zero and with a stop watch measure that time.
if all 4 injects take the same time to leak down to zero then the are in BALANCE.
if pressure was 50 the FPR is bad.
if it leaks down before the injector pulser is used then you have leaking injector , unplug all 4 now, still leaks now? that is FPR leaking or the fuel pump check ball inside bad, (rusted) to test the injector for balance the Residual :25 PSI , after 1min test must pass first. ok?
this is all MPI testing all shops know how to test MPI and doing FPR tests fully is #1, or the injectors will not inject the correct rates of fuel .
best is save this file, so you have it.
