pump only runs cranked or engine running. (NORMAL)
key on it can run pump for 1 seconds, this is called prime
no single tech can run that fast to the pump.
so key on 5 times to purge the air in the lines.
so is spark good?, it must be good if the PC sees (detects) spark bad, i
t cuts feeling 100% dead, so car does not catch fire, by law.
same as key on, pump is not on , key on after the prime pulse.
302 is cylinder misfire, reset it and it is gone.
always check spark first. not fuel , fuel is last of the big 3.
- engine good
- spark good
- and if spark is good ,fuel tests is now allowed.
my guess is 1.6 L ZM-DE. this engine? aka Z6
16valves, DOHC. belt drive,
gen 9 car.
so 22 years old and running the cam belt way past 100kmeters odometer, wash wear repeats ever 100km for got that rule?
if yes the
belt slips and the CMP and CKP sensor fail for sync
when SYNC fails inside the PCM it cuts spark and now bends over the head valve.s $$ super expensive fix that./
for $30 belt.
so now you know why we check spark on all 4 spark plugs and not just 1 ever.
took a bath i fuel ? just for lost spark??? (sad face)
gasoline(petrol) cannot burn lacking spark this is no diesel.
and injections of fuel on a no spark engine is a huge fire hazard for sure in any kind of crash. OK? that is how it all works
pure PCM logic and laws making this happen, just like this.
if spark was good and gas tank dry,
the engine runs on sprayed test fuel instant start in a can
runs for 3 seconds and stop repeat 3 time or more, see the engine sounds good and is.
if fails this test, spark is gone or the cam timing why the heck off and is the main cause. Ignoring the belt is #1 cause. on all belt cam engines. vast.
