Where do you find the fuel pump reset button for Suzuki Liana 2001 (in unstated country)
it's not a ford, (park that ford manual now)
short answer, only in your dreams....
got 12vdc to the pump? cranking?
got spec fuel pressure cranking and running?
as does not checking spark first
the PCM cuts fuel if spark is dead, (3 ways)
3 ways. and all 3 stop crash and burn, as seen on TV.
why not post symptoms, then ask for how to diagnose this problem.
instead of guessing wrong.
the tests are easy , ask how.
if you dont have tools its mostly just flaying about.
no start 101:? (pasted in , vast times)
Cranks over fast, but will not start. (posted , 100 times now....)
Mr. Otto Cycle engines,.... (spark/gasoline/petrol)
no start or stalls, and will not start now.
There are over 50 causes. even a simple rusty fuse. (or worst hair line cracked)
Head lights work and not dim? CLuster lights all work like new car?
We use PHYSICS to find cause. Never guessing. (meters , gauges and 1 scan tool)
About 1 to 10 tests.
1: Fuses good?, all EFI and spark fuses?????not just looks GOOD (test them)
2: Check engine lamp glows key on, ? if not? see #1
3: I crank engine, it cranks fast. but do you have spark on all cylinders. (not just 1 , all)
4: Is spark timed right, not 25 degree's retarded, if retarded illegally, that is the cam drive slipped. (belt or chain,no matter)
(5min with a timing light and wow, the bad ignored belt, is discovered)
The cam belt is a 60k miles service, point on most cars. (with belts) so.....
5: if you find spark is dead on any cylinders and is not bad spark parts (wires,cap/rotor/plugs)
I then use a scan tool cranking and see P03xx DTC errors. P340s or P355s cam/crank sensor dead.
or if pre-1996 cars in USA, we use the 2 cent paper clip, diagnostic jumper clip, to find DTC errors.
DTC means "Diagnostic Trouble codes"
6: spark is good on all, now.... note my order here???? not gue$$ing, just testing,,,,,,
so we then use a can of "test fuel" now. 100 years we do this... it's a not new idea or magic.
watch Scotty do this here.
Does it run on test fuel.?
NO. bad engine. check compression, 150psi min. times all cylinders, not just one.
Engine ok, but spark is bad, will cause test fuel test to fail.
YES? runs for 3 seconds now, then you lost fueling. (congrats getting this far !)
Keep in mind all EFI gas engines, the brain cuts fuel if it sees 3 lost spark issues.
"CMP dead,CKP dead,Ignitor dead" to prevent fires. so not scanning the PCM you will never find the problem.
What to test next is a toss coin deal.
NO DTC errors, i then whip out my trusty fuel pressure gauge, cost all of $20bucks (investment grade it is with pay back !)
check fuel pressure next. it must be in SPEC range, as this is NO CARB car. it's EFI.
EFI means Electroinic fuel injected.
I'll not show all fueling tests , that is 10 pages of text, or read a ASE book on topic.
but... in short....
got 12vdc to the pump cranking?
do you? (any $10 voltmeter made works for this test.... or better)
you need to crank it to prove pump is dead... on half 1/2 the cars made.
we do all, that way, so that we don't get confused or wonder how EFI logic works.
"programming varies by that in the ECU" Some ECU/PCM had reflashes that upgrade this LOGIC.
The Suzuki J18 is a classic example of change. (must crank, just like 1989 cars)
If fuel pressure is low, the injection rates will HOPELESS.
if fuel pressure is crazy high like 60psi, the engine will flood hopelessly.
our engine here runs 30PSI.
we can do injector leakdown rates and balance test. and for sure im not typing that out...
here is the USA page for Suzuki books
note how Liana is missing.
we dont have it.
next time post your country so we can give you answers based on how your car is made , not ours.
