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