DO you have an OBD scan tool for this car?or working blind?
keep an open mind, do not assume anything but diagnostic logic.
and win, i can tell this posted questions is for you Assuming.
please stop FEELING and start testing,use facts not feelings or assumptions.
(my instructors yelled this to me 100 of times, and then learned it the hard wAY)
do the the tests. the right way.
1.6L MPI ,
do all 4 injectors fire with the NOID? with equal brightness?
if all 4 fire and
all 4 are dry (look at spark tips or do the injector balance test)
do you know how to do that test?
its not hard. YOU HAVE tHE TOOL. Use the tools right.
Duane's world
see first 6, (injectors)
seen here in video and is covered in my injector test page,
works on any MPI.
what he does is crank the motor with 1 injector connected. and the pressure gage.
he then sees the pressure drop (yup, injector squirted)
then repeats each time on injector connected at a time.
and takes careful note. did all 4 drop at the same rate or fail to drop at all>????
see the master do his craft.
the injector is hidden, but there are 2 ways to see what it does.
spark test.
the balance test.
not to mention noid results and better a scope.
you do know that noid cant find weak drivers in ECU.
The NOID is toy level device. only a scope is top dog.
the scope can see injectors hanging up an other anomalies.
i dont expect you to have a scope only want you to know why real shops
find problems 10x faster. better tools.
a $100 tool to boot. (i like HQ used scopes)
PS
when you say
that means ZERO
there are many tools and ways and methods, to do checks.
tell tool. or way,
EG:
the tachometer goes to 300 RPM cranking,if not ECU cuts injection.
Is the TPS sensor TP pin, (i think this year is a 3 pin TPS) and must be
at about 0.5volt, with cold start valve retracted. if at 4v the ecu will CUT ALL FUEL.
I do not have full spec on this car, but the throttle must not show over 75%
a scan toll excels at finding this silly fault.
I Look at spark tips,
i used the noid, with injector connected and disconnected
i measured ,each injector coil with ohmmeter (Resistance) they are all 10ohms
i then listened to them using test fuel. vermmommm
i hear the clicks, it is hard do with a crappy rubber hose, i have a real electronic
stethoscope ear, may DIY tests (hoses, ) you need to repeat it 5 times, to be sure.
you get what you pay for in tools...time or money.
i connected my sonic tool to each injector and all 4 are dead.
i'd the tachometer swinging up scale cranking.
i posted extra tests, because I feel you do yours wrong or skipped important checks.
wires can open at any time. and pumps go to zero
etc
do the tests while the failure is present.
it runs on test fuel, id still do a compression test.
just to check off , the first test . good motor.
i think spark is ok. it runs on test fuel
but look at timing, ?
if the cam belt or chain slipped it can slip 2 ways,
retarded, or advanced,
some times test fuel works with discover timing wrong
I FACT is connect my light at first look, just to see if while cranking
the strobe lands right , if not , im ON IT.
the spark timing will be way off, if any chain or belt slips.
its the best sign ever. and is what a 5 min job.. freeze jumper planted.
usually it retards, due to crank wanting to go faster than cam.
last idea
again.
ALL FOR NOID lamp checks, DEAD? you never said.
injectures fire and flow for 3 reasons
full 12v on once side, 5mS pulse to ground on the other
and 32psi on real
and injector not packed, closed, they do have 10micron screens, you know.
all 3 above pass. you did the test wrong.
use the balance test.
