Get the wiring repaired correctly....sounds like they should have replaced the fuel pump relay and instead bypassed it and wired it to the wiper circuit?

1.6L or 1.8L vastly different engines... and EFI.
fuel to the rail , only means the pump is active , never good.
28PSI is minimum on all cars. 1psi will never start a car. ever
and the rail will shoot fuel, all day. it fruitless , unless the rail is dead.
see?
First the laws of EFI. (works all gas EFI)
  1. all fuses good.
  2. 12vdc to EFI system , below 10v is bad. (see lamps dim? bingo)
  3. The PCM (EFI brain) will never inject if it sees CMP/CKP or spark primary dead. ever. so, spark is first.
that is double reasons, fuel cant burn if no spark and if ECU
thinks spark is bad it cuts fuel, (fire safety and fuel hydralocking reasons)

so you connect any scan tool to the DLC, OBD2 port , by knees.
and crank for 5 seconds, release key, no turn off
see DTCs (errors) for CMP, or CKP sensors (cam/crank?)
bingo
no, then you crank and look at the RPM PID , live data stream the scan tool, see RPM go to 250rpm cranking, good.
ok , PCM thinks all is good....

i then check the #1 injector with a NOID lamp
i crank it flashes, good.
if not , i do all injectors , if one fails the pcm is dead on this line.
if yes, all dont flash the PCM is seeing some gross errors. ask. why./?
if all flash, then the fuel rail is dead. and your rail test was useless.

until you discloses engine option (size) I cant give spec numbers.
i then connect my fuel pressure gauge $20 tool to the fuel rail test
port, and i get 10psi, FAIL
i check voltage to the fuel pump cranking, i get 8v, bingo bad wiring
or bad fuel pump relay.
say 10psi and 12v at pump cranking,
the pump is bad, or the filter clogged , or the fuel pressure regulator
is stuck wide open killing all legit pressure.

that is how i do it.
keep in mind the PCM cant see fuel pressure on most cars.
some newer cars have this sensors. (nice)
low fuel pressure,. renders the whole EFI , useless. just junk.

Am not getting power to fuel pump an alarm system was installed after market would that affect fuel pump


no 2 alarms are the same.

follow the path, of the pump. using a volt meter. (pink wire)
some cars, only run pump for 3 seconds key on, and cranking.
so take 2 people.

No start


the fuel pump is in the tank, and the spark plug wire's could be hidden under a plastic cover on that motor

2000 Suzuki Esteem (1.8) Fuel System


No SYMPTOMS stated, (sadly)
the J18 engines, twin cam, chain drive cam, nice motor.
an under stroked, J20. it is.. and share most parts.

alldata.com covers it.... and all cars... mostly.
for sure esteems (used books real off Ebay, if lucky, do a watch on ebay)?
and for sure Suzuki, the FSM is $4 to read. and posted 100 time here. (more ) this the real deal, (McCoy)
https://suzukipitstopplus.com/Products/1182-2000-esteem-service-manual.aspx

the filter, and pump , no need to replace pump unless
it has 12vdc to IT CRANKING< and filter is new. AND, pressure is out of spec. (see spec, below)
a gauge is $20 and way more easy to use than a bath in gasoline
for sure.and a $10 voltmeter from walfart.

now the Esteem secret (just in CASE)
"Remove rear seat cushion, rear right seat back, right side sill scuff, right front partition trim and right rear door opening trim."
bingo, a secret access port.

now the spec.
31-37 ?idle PSI
this is the fuel pressure at the rail, at idle.
cranking is 6 PSI more
driving up hill, wide open throttle, pressure rises to 3- 6psi more that idle. (near)
if pressure is low, check for 12vdc to pump, first.
then make sure the FPR works.
they can stick open closed or jam. and it must work right. or fueling will be ALL wrong. (cars this old FPR love to fail)
this engine ECU has program revision (flash) that causes
pump to not run key on, (read TSBs on same at suzuki...)

so, crank it and check pressure cranking if not starting?
or if it does start (you never said) then check at idle
and WOT. the PSI ( then gun throttle see pressure jump way higher) if all this pans out, forget pump, and FPR.

did you scan the PCM yet, that be like first..
all scan tools (real) work on 2000 cars.... all do.

Suzuki Baleno (esteem) 1999. Engine Idle RPM not stable


you probably need to check the butterfly. its the compinent that controls how much air goes into the engine if it is weared than in idle state air leaks into the engine sometime more sometimes less and cause fluctuations in rpm

secondly there is a rpm switch which controls the rpm you can replace that switch and check

Check throtle position sensor... one section closes a set of contacts when you take your foot off the accelerator... this is sent back to the engine control computer which adjust the timing to insure the engine stays @ ~ 800 rpm. It's easy to set with just a simple multimeter...
