2002 OLDS Silhouette GLS and NO ENGINE TOLD at ALL, but bingo this engine says wiki.
3.4 L
LA1 V6
10X MORE CLEAR ENGINE CRANKS OK BUT DOES NOT START RIGHT? the delay cause is unknown.
EFI 101 day, how does fuel flow in FI fuel injected systems
Electronic (Learn that FUELING is last NOT FIRST)!!!!!!
first off running any pump there dry wrecks it,
the
fuel pump is fuel lubricated and cooled (both) so dry is super super bad. (carb days are gone now)
ok here is how EFI works
the EFI brain called, PCM, does not inject if the PCM detects spark bad. (and tells you if scanned that) this is to avoid crash and burn as seen on TV>
pure hard computer logic inside PCM does that.
Like:
CMP dead or CKP dead is spark dead hard. so no fuel flows by DESIGN (and by law too)
checks. to do. in order matter.
all fuse good
IMMO lamp (VATS)PASSKEY III(tm) on the dash not glowing in UNHAPPY mode !@!!!!!!!page 2-6 in the user guide in glove box.
the car came new with 2, PK3 keys, lost the second.
lost the guide it's free here.

OK PASS-KEY lamp is HAPPY.
check spark (oops forgot step 3, ) and spark can be tested on all gas engine cars for 100 years, and then we use instant start in a can.
and it runs for 3econds, but IMMO also cuts spark at 1 to 10 seconds, immobilizing the car/engine .(yes tricky, but gee the IMMO lamp did not lie to you, if it is blinking in unhappy mode.
so we now scan THE pcm (OBD2 PORT) AND OMG IT KNOWS WHAT IS WRONG,BUT YOU FAILED TO ASK IT.
and last is spark never first.
fuel pressure at spec cranking ,using a fuel pressure gauge.
a 2 man test, one cranks and 2nd checks pressure for factory spec pressure PSI. (or bar)
pass-key facts(in your glove box guide)
Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
got this error? , it will not run BY DESIGN.
