I have 137,000 miles on a 3 cyl. 1998 metro, It stopped running going down the expressway, there's no spark and the cam stills turns when cranking over. Two days before I put a new o-2 senor on and it drove fine the next day.What do I check next?

I would check to see if there is any spark coming from the coil.If there is no spark there I would start looking at the fuses.Check all the fuses sometimes they run things like that through other circuts as well as it's own circut, so a fuse labled ECMB,IGN,ECMA.... should be checked also.

1991 geo metro engine light came on and it die now won't start motor turn over but won't start


did you try cranking with throttle open 100%
this clears flooding this cuts the injector(s) dead.
does it/
try fresh spark plugs, are the 10 years old?
try test fuel (spray)? run for 3 seconds,
if not, you lost spark check fuses.
if you have spark and it wants flood is the cam belt 10 years old too, if it slips it will not run again, ever.
until that is cured.

What generates fuel injection pulse on a 1994 geo metro base model? I have replaced alternator, TBI injector, and ECU. Checked relays, fuel pump and filter. Feed and return line are clear. On startup I get...


The PCM (ECU does that) its part of what is called EFI, electronic fuel injection, it's a computer, that gets inputs, and uses those inputs to injector perfectly at ALL times.
what engine? 3cy. or 4? is it TBI injected or MPI injected
1 injector or 4? we need to know that first.
does it run on test fuel for 3 seconds.
when was last time it run perfect, last week last year. what?
first off stop guessing, you can go broke that way.
want to diagnosis it? the steps are easy. if fuel is good..
  1. fuses good.?
  2. CEL lamp glow keyon, if not ECU is bad. or bulb , it must glow.
  3. compression over 150PSI on all cyl. (w.o.t = wide open throttle)
  4. do a 60k, mile tune up yet, filters, spark,. and cam timing belt.?
  5. if not, why wait?
  6. 6: is spark good tall cylinders not just 1? is the timing way off if yes, the cam belt did slip, do not fiddle tiiming, fix the belt. first.
  7. ok it now magically runs on test fuel for 3 seconds and sounds great. so we do fueling last.
  8. fuel pressure tests are next. takes $20 gauge got one?
  9. ill stop here, as fueling tests are long play.l..... ask. if you can get to step 9,

I think all 94 metors are TBI engines, one injector
up to 1997 inclusive.
then the 1998 offered 4cyl, MPI injected engine.


have you learned how to use flash codes (DTC) yet?
insert jumper , key on, see CEL lamp glow and flash 12s'
the crank for 5seconds, see if the flashes go to 41 or 42?
bingo if yes.
the TBI allows the mech to watch injection, at the TB.
with top hose off. you can watch it inject as person 2 cranks.
does it?
the ECU brain cuts fuel at the first sign of:
  1. lost spark (to stop fires)
  2. lost Cmp sensor, same .
  3. TPS ground wire busted and ecu things foot is W.O.T (super secret unflood mode) (or TPS cracked in half inside)
or total loss of fuel pressure.

I have a 97 geo metro 4 cyl engine the other day broke down the wrecker driver said sounds like fuel pump is bad. I replaced pump and filter still would not start. getting fire. Last night I started it...


first check fuses. (test them)
then check for spark at all 4 cylinders. good.?
if not timed correctly (spark) with timing light, then the cam belt slipped. (oops not changed at 60k, oops)
if all that is good engine runs on test fuel, does it?
if yes, you lost fuel.
easy huh, watch scotty

I have a 95 Geo Metro 4 cylinder automatic it wont start it turns over but it won't start and I have no spark could it be the timing would that do it if the timing is off?


ok penny , you have a G16 engine
and no spark, that mean at all 4 spark plugs and the coil?
5 places, ?
if the coil makes spark, but not at plugs. that means
the cam belt slipped, did you forget to do the 60,000 mile service?
sure.
turn crank by hand does distributor rotor spin?
No , belt snap.
same check , look and oil filler hole, does the cam spin? , cranked hand turned.?
no ?, belt is gone. CAM TIMING BELT.

yes turns, then check compression (a tool) at wide open throttle.
if compression is over 150 PSI, then ok
if way low, like 80 the cam belt is slipped,
all easy tests, all less that 20 bucks in tools.

FIRST check fuses.
then check that the Check engine light glows key on
if not , there is no DC electrical power to the ECU (injection system or spark or both. the ECU cuts fuel for no spark, (hint))
there are 3 fuses, that must be good, to start any suzuki this year.
2 are critical.

if all this is klingon ?
get it serviced.

Intermitent dieing


metro, 1.0Liter>? 3cyl

or the LSI with the 4 cylinders.? TBI and not MPI

yours is TBI, One injector engine MPI came out in 1998.

your car has OBD2 computer so any scan tool will show

why spark is gone (if). (precursors ) cranked for 5seconds,



(what does has fuel mean? wet spark plug tips?)

got spark? it stalls and wont restart have half hour>?

intermittent engine stalling. seems starts cold and fails hot engine.



on all EFI, (besides a tune up) we check this.. (a full 60k tune up?)



1: if you loose 12vdc main power, at stall>? (dash lamps dim or die,

head lights dim or die? bingo!

no.

2: can you save the stall with a fast right foot?

a: easy (isc stuck closed?)

b: tad hard. (EGR main stuck open or or low fuel pressure)

c: impossible. (lost spark or near zero fuel pressure, 10PSI is no good.

which is it? and is #1 key to solving any EFI stalls !!!

3: lost engine compression say hot, never set valve lash ever? or cam belt slips or has slipped. ever do a 60k belt on cam, ever?



4: bad spark, weak, or dead, at fail, if spark timing is way off (check it) that mean the cam belt is bad and slipped. 60k mile service skipped.

5: bad fueling, (last) and the most complex.





that is the correct order, you can skip around but it only delays the discovery.

1 Bad DC power, 2 bad compression,3 bad spark 4bad fueling.

Example1:

you key on, and get CEL glowing, most likely the ECU has power

as that lamp tells you it has.

then you find its flooding, 99% are never tuned up, or lost spark

you check spark its gone, you check that cam spins (oil filler hole)

you connect scan tool and crank for 5seconds, the tool shows

CKP or CMP bad. the DTC error codes will tell you!!!

if spark is good, use the operators guide , for flooding

it says :crank at wide open throttle to clear foods"

it starts, and floods again. oops.

you check spark timing.and find the timing way off, retarded.

bingo the 60k belt slipped, fix belt.

you check compression (it should have been first) and find its 80psi

not 150 PSI (W.O.T)

belt slipped. (they all do , ignored, )



lets do one more,

: example.2

spark good,!

timing good on dizzy!

compression as spec. 150 x3 or 4.

it floods.

i find fuel pressure at 60PSI , 2 times spec.

i find the regulator bad, it fails all 6 tests in the fSM on this device.

or the fuel return line is clogged.

hope his helps. post engine size, and cyl. count.

and if ever tuned up this decade.

Dodge stratus code p1391 replaced knock sensor and cam sensor still nothing


in my code book gave me intermittent loss of cmp or cpk
for 2.0 L are you having any back firing problems ?? iif so timing belt may have jumped one tooth . just trying to help hope this gives you some other things to look at ,good luck
oh look up code p1390 just found it . explains more what i was saying.

The mil light doesn't come on at all, no spark no


i would  check the crank position sensor. if this part is bad the cars computer will not recive signal to send fuel or spark.
