How do I check the power to a fuel pump on a 2004 Oldsmobile Alero
what an easy question on EFI.
well dead engine RIGHT?, not told the evidence at all
did you buy a dead car?
well if the PCM sees these hard errors.
- PCM sees spark bad in any why it cuts fuel dead 1 or 2 ways. by law and to not do Crash and burn as seen on TV . facts.
- pcm sees throttle , fully depressed due to driver doing WOT magic secret UNFLOOD mode. or TPS bad.
- PCM sees CMP or CMP bad or grossly out of time, cuts spark and in turn(logic) cuts fuel 1 or 2 ways. or both.
- IMMO is not happy the IMMO lamp does not like your KEY and will not spark or will not injector or on some not crank or al 3.
- IMMO is the tech name for engine IMMOBILIZERS all.
to test the pump , we must crank it and do test at the same time.
we check IMMO lamp, and fuse first
scan the PCM PCM cranking , OMG it told me why it fails wow OBD2 we love it , in USA,(our invention too)
the if no progress voltage at pump pins or hear, 12vdc is a bad pump fuel pressure dead ,under 30PSI is dead.
if 0vdc at pump and at Fuel pump relay the relay might be bad;.
Need wiring diagram for power windows 2002 Oldsmobile Intrigue please.
Bench-testing the driver's window switch is performed by checking for continuity between two pins using a digital multimeter; pins G and E when in the UP position and pins G and D when in the DOWN position. A better way to test the circuits would be with the window switch connector still plugged-in and the ignition ON; check for voltage on pin/wire E when in the UP position and pin/wire D when in the DOWN position. If the multimeter does not read battery voltage, the switch has failed.

93 Oldsmobile cutlass ciera s fan not turning and car overheating
old 93 cars, have lots of problems.
I guess the fan is in front of the engine and near rear of the RADIATOR.?
no engine told of 3 at all and they are not the SAME.
first is check for blown fuses, (easy low hanging fruit,no?)
the fans is electric, so says SM service manual
and has 2 wires.
one is ground
other is 12vdc to the fan relay that must be good.
the fan can be hot wire tested, easy
boy those old drawings are a mess.
fuse link F blow,, op right
I do not know if this is AC only or mixed. (engine/AC / fans)
How to install neutral safety switch on a 1988 oldsmobile 98 regency brougham
Doby , you have like 100 posts here for one car. ( a record)is this car really that sick? but never told 1 problem at all. this post.just a HUNT, game.?you posted this many times and never bought GM Olds full service manual for it, that tells this answer clear as day./The PRNDL switch is on or inside the transmission and no engine told nor transmission told exactly how can there be any answer?"Do you keep it in park or neutral"THM440/4T60/ME9 TRANS (ME9 is RPO code)<< guess 1THM440 is original name or pure hydramatic box.GM box it is.there is shift solenoid in the shifter console,Park lock out, has long history of changes.on some the PRNDL switch on side if tranny box goes to ECUand if not in park or N, no spark happens.on others there are cable to key switch to shifter linkagethat blocks key actions using this cable. and more. manuals for this 34 year old car are hard to find, now.the real service manual will cover al Vin cars that yearit will cover all park lock out schemes use then, of at least 3.pays you 20 bucks and see what is here.https://eautorepair.net/Marketing/Default.asp1988 only books then so online help is sparse and are hand scanned pages, only, but , at least try.
99 oldsmobile silouette Defrost blows cold but face blows hot
band damper motors (actuators, servo's regardless type)
you already now the heater core is 180f + hot.
even touching its 2 lines at the fire wall proved that
and OBD2 scans show ECT reads 180F so engine side is good
so then you fail to know the days has what is called heater./distribution air system.
that huge box of damper there that love to fail
even the service manual covers this.
mine even shows removing the damper motor (vac or electr)
and turn the damper hinge rod by hand to prove the damper door is not stuck if not stuck heat flows, hard. to one of many outputs called MODE dampers.
we then test the mode dampers. see why it fails.
all this is under the dash keep the hood closed or go broke throwing part not bad.
the SM service manual on line shows chapter HVAC
and covers every test to do , in all Chrysler products.
oops I see old vacuum servo motors here , actuators modern name
bad controls or bad servo's or even fell off vacuum lines
I see 2 motor servo's too, temperature damper DC motor
and mode, motor drive. called electric inlet actuator.( is Recirc )
and and AUX motor damper drive.
found the hybrid schematic for this car, the whole thing vac and electric.

ONE CAN WATCH EACH DAMPER MOVE OR RUN THEM BY HANDS
AND EASILY PROVE WHICH OF THE 5 FAIL.
SENSE HOT AIR IS ON THE LEFT THERE
WE KNOW KNOW VACUUM SIDE IS BAD, HE DAMPERS, STUCK
THE SERVO BAD, OR THE CONTROL PORTS TO IT ARE BAD.
EVEN A VACUUM LINE FELL OFF OR ROTTED OFF. 23 YEARS OLD
98 Oldsmobile 88 TRANSMISSION tcc SOLENOID location?
well the service manual shows this box.
TCC clutch lock up or this
Torque Converter Clutch Pulse Width Modulation (TCC?PWM) Solenoid Valve Assembly?????????
Automatic Transaxle - 4T65-E
The "T" means transverse boc.
E means shifted 100% by electronics TCM brain, most are inside PCM.
no engine told but this is the most common box, GM made and an put it in vast cars sold world wide , for them and other makes
and lots of tops manuals covering it
the answer is
the TCC sol is inside the box. above pan'
the TCC is mounted to the valve body.
exactly here, as seen in the service manual and GM books on this box.
there is Brake TCC switch that kills TCC function, braking.
the clutch unlocks TC)
there is TCC-PWM sol on the valve body
there is TCC pressure switch same place to tell the PCM TCC did lock or did not lock up via pressure.
2001 Oldsmobile Silhouette. No crank, no start. Crankshaft position sensor been replaced. Starter to replace, battery replaced, no power to the PCM fuse.
this is not clear at all (is 3.4L engine my bet)
the starter is silent or not? if the starter motor spins the enigine crank shaft , fast that that is cranks ok not start engine.
no crank means. the crank shaft never spins
and that as a few causes,
blow fuse test them all?
crank in park and in Neutral too? N can work and P fail on any car.
no power to PCM fuse mean main power is dead main 12vdc power buss is dead. and that is much larger fuse even 100amps.
if you scan the PCM well that action will be dead. lacking PC power
so here is that power feed, battery must be 12.6vdc rested, not 10v
here we go ,2 paths dead, starter motor and PCM dead power.
Fuse link C blow out. GM gray coded,same goes fore Fuse a1/2 blown.
fuse link A, blown GM rust coded make alternator 100%^ dead and now the battery dead too ,lacking working ALT.
next is fuse link Z (GM gray) runs vast things.
I wonder what fuse is this PCM fuse as none are marked that.
there are 100 schematic to see, I am working throught them all to find PCM
are head lamps dead, are brake lamps dead?
head lamps work key off, so is always fix it first if dead.
fuse (Fa1/2 ) PCM/ABS fuse 10amps the a1 side is main power to this fuse. and this also kills dead the transmission range switch PRNDL and starter too dies.
So fuse A1 side is your critical failure point on this car.
so maxi fuse 40amps blew out from a short.
A1 FUSE GOES HOT KEY ON ONLY. (NO IMMO FAILURES IF HAS IT.
IF NOT a ign MAIN 1 FUSE 40AMPS IS BLOW
OR POWER TO MAIN ONE IS GONE.
mIAN1 IS WIRED HARD TO THE BATTERY MAIN
ALL MAXI FUSES ARE, SO IS BLOWN THAT FUSE OR THE KEY SWITCH IS BAD.(IN RUN)
Why does instrument lights go out when starting van but van won't crank
This problem is typically caused by a discharged battery or a poor battery connection. These conditions can allow some components with a low electrical load to work properly, however when it comes time to start the engine (which requires a high electrical load), it will not start. The first thing you'll want to do is check the battery terminals. Look for signs of corrosion (green powdery buildup) at the battery posts and clean as necessary. Also, attempt to twist the terminals on the battery posts by lightly pushing and pulling on the battery cables; they should not move if they are properly tightened. If no issues are found, attempt to jump-start the vehicle. If jump-starting the vehicle works, you could have a faulty battery or a parasitic drain, but a faulty battery is by far the more common of the two failures.
