Try having someone turn the key to the start position while someone else taps on the starter with a hammer.

2000 isuzu trooper no start with slow crank loose 4 volts at starter


automatic or stick>?
no engine size stated. gas or diesel.
slow crank, 250 -300 rpm is normal.
so did you AAA tow truck style , jumper cable crank that car off a running donor car yet>?
just that act (test) speaks volume for cause.

what does loose 4v mean...??
10-11v is normal voltage at starter. cranked.
4 v at the solenoid can not even begin to close it,
or did you mean the 12vdc is 4v lower that 12vd. which is 8v.
perplexing. (3 cheers 1st poster here with voltmeter, im am truly shocked,(no pun) honest reply.......!!

A fuses blown. (DEAD CRANKS)
DEAD BATTERY
BATTERY BAD
bATTERY JUST DISCHARGEd.
wrong sized battery in car, (tiny)
LAST DRIVE? the charge system died, and now battery is weak. fix charging system.
left head lights on, cure , charge battery.

battery terminals rusty !( yes they have 4 ends they can rust or get loose) 500 amps here so must be clean and tight.(bat terms)

jumper cables jump starts car ok?, yes, then battery dead.
battery bad, battery only discharged ?
next:
jumper cables don't crank fast, then hot wire the starter. (big wire to tiny)
more testing....
with known good charged battery (12.6vdc rested)
i hot wire the starter solenoid.
i monitor the voltage at starter actual.
with a volt meter.
most cars do 11v, in warm summer.
if much less, say below 10v the starter will be slow. so i monitor battery terminals volts.
and if ok, there, the cables are bad. (voltage drop on cables is that, yes, cables do fail.)
or the starter is partially shorted. or engine seizing....hand turn engine crankpulley and feel it.? feel normal, ? or cant move it...?

if i suspect a bad starter i use my ammeter.
the starter current will be about 200 amps .
no engine stated so.....i guess....
if it goes to like 600+, the starter is shorted.
I have an amp clamp amp meter, that allows me to see and find the hard cases...

I have a96 isuzu trooper just had the starter checked and its good but still not doing anything when i stick key in theignition to start could it be the security system


NO CRANK. 96 USA car,(are my answers) check all fuses 1st !
C1 and FL1 and FL3 fuses good?
4wd ? or 2wd. auto or stick shift?
which engine? size? and cyl count....??????? 2.6 or 3.2liters?
wiring varies by engine type, so i guess more....
Does it crank ok with jumper cables (?) to a running donor car?
can be lots of things, gee the IMMO light in the dash is clear.
is it glowing? (the operators guide covers that.)
is this a USA car or Canada? some are different.
got a voltmeter even a $10 walfart meter works perfect.
or do you want to gue$$ and go broke fast. its your cash but/?.......
3.2 v6 shows no IMMO pins on the PCM...... so...?? in 1996

  1. battery dead, or discharges or terminals at 4 ends bad on cables.
  2. Fuses good.?
  3. turn key does CEL lamp glow?(cluster) if not , its not going to start with a dead ECU.
  4. no is the IMMO lamp glowing.
  5. key to start, (crank pos) silent.? now shift to Neutral like the the operators guide shows, cranks now? (a/t trans and no trans stated, so.... i guess away at what is there......
  6. does the starter relay close cranking, if not, work back from that and dont blame the starter, motor. fuse C1 runs this relay. is C1 good. or FL1 or FL2 fuse blows,
  7. ill now show the schematic (wild guessing engine and transmission..!!!)
this is the cranking path, (good starter and battery and cables)
the top of the drawing is the main power 12v feed from FL1 and FL2 fuses. (mains)
then you turn the switch to start
and 12v goes to fuse C1. got that?
then to the a/t box PRNDL switch. and in park or neutral
the 12vcc passes (10 to 12.6) cranking, or more if starter dead.
goes to the starer relay. the relay closes. does it?
if not it will never ever crank the starter.
if you have manual trans, the part in ? below is a clutch switch (pedaL )


25688029-s4ytlrl2eq1g0qp4vyp302wy-3-0.jpg
NO ANTIHEIFT OPTION.
the bottom of the coil in starter relay is grounded. full time.
if you have antitheft option the Antitheift module makes up that ground. if happy.
so if the pin 5 on relay is 12vdc(dead relay) then the IMMO is unhappy. good luck fixing that.....

if IMMO not happy,
we then try both keys, lost your spare?
oops.....

one voltmeter and 15min work , or 10 less if IMMO lamp glows or flashes.
does it?
my post assumes, all things can fail, lacking, good input on dash lamps....

2002 trooper that will not start. Battery ok, new fuel pump fuse. Cranks but will not turn over. What should I look for now? v-6 cylinder


did that mean you had to replace the fuse because it was blown? If so the fuel pump or fuel pump relay may be bad. Check for tight connections-no corrosion- at the fuel pump and fuel pump ground.

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

The alternator on my 1992 Isuzu Trooper fried (green smoke pouring out), changed the alternator, charged the battery, checked all fuses; still no power, car will not start (no clicking sound, absolutly...


do the head lights work????????that is first
becaus it works key off a speaks volume to any tech

wild guess:
battery installed backwards or you made sparks
remove it or alt or starter.
fuses blew.
easy peasy japaneezy
or worse,there is always that.?


elaborations. pretending HL work.
buy and $10 voltmeter and end the guessing?
5min work and bingo.
wow this fuse has 12vdc one side and 0 other.?
or key on fuses, same.
5min


there are many ways to do this.
start at end work back
start and begin (key) and work forward
or the middle (cuts job in half too)

so i go to the starter solenoid first.
if head lights dead i work them first....
starter 3 lugs.
outboard lug first.(batter + is battery installed backward?)
got +12v on the big lug (y/n) (outside lug)
connect meter neg test lead to battery neg lug for all tests.
if voltage drops fast? or does cranking
bad battery ,starter shorted or cables (or discharged battery) (we use an ammeter to discover shorted starters,or hand turn engine for seized engines.
next tiny lug, (called Key Line)
it goes hot 12v? cranking. so turn key.
does it go hot? (hot means 10to 12v cranking0
if yes, goes hot cranking on the tiny lug
(yes starter dead , or the battery minus lug is loose , the far end of minus bat cable must be tight.
no? that means the KEY line is dead.
the car if a/t tranny cuts the key line via the P/N switch,or some immobilizers., i stop here on key line, ask.

some cars have wire fuses, looks like wire, and are not. "fusible link wires"
if you change out starter or alt without battery neg lug not disconnected in step 1 ,you risk main fuses under hood(blowing or far worse)
so what does "good fuses mean" OP? (the looks)>?
or just dash fuses. tested skipped under hood.
fuses that look bad are
fuses that look ok, can in fact have hair line cracks so we actually test them or waste Huge time.
and go poor. (tests done wrong are highway-to-h3ll)
or looks like dog chasing his tail.
0 ohms good
12v both sides key on, good.07316db1-a220-4760-a228-0a546c4edbe8.jpg

88 honda civic wont start, it cranks but then fills the manifold with fuel-replaced injectors,coil,fuel filter,fuel regulator,igniter,ignition module


a couple things could be the issue: 1. check battery terminals and cables, look for green oxidation on the Neg and Pos cable(s) and check where the cables connect to the battery (normally white caked on clump) clean with baking soda and water combo, be careful use gloves and goggles. once the post and connectors are clean, apply a little vaseline to both terminals. 2. have battery checked out to make sure it is fully charged (autozone or local auto parts store should be able to do this for free) 3. check starter connections (I had a similar problem and one wire was not secure, this fixed it for me). 4. check fuses and relays, in addition to the cable, I needed a fuse that limits the voltage coming into the fuse box. 5. starter solenoid, this could need replacing, it is not engaging the starter to crank the engine. Good Luck and I hope one of these can solve your issue!
