2002 chevy tracker 2.0 (NO FIRE PLEASE HELP)

2002 chevy tracker
2.0
2wd automatic

welcome:
2.0L J20 engine twin cam, DOHC., has 4 COP coils on top, USA car has those,
all 4 dead or just 1, (matters, if all 4 are dead) fuses is next.
do not pull the aluminum body CMP sensor, only pull the plastic part, or timing can be a huge huge difficulty.
did you look to see if the cams turn? yet.??????????????????????(seen down oil filler hole, i think is easy... forget, if that works. that view.
best is fuses first, then scan it with OBD2, if you crank it for 5 full seconds and the PCM does not report, bad cmp or ckp then they are good.
do not pull the CMP until you ask how to do this,its not like changing a light bulb, let me explain the timing freeze jumper if it has one.
my 04 they deleted that precious jumper and guess what its a suzuki scan tool to set that. ask how to avoid all that. its on my sparks dead page, J20.


me too, I love dead cars. all things dead, in fact, cheap,, fun to fix too.

I picked this unit up for a couple hundred bucks and it's really nice.
Previous owner had assumed he ran out of gas because it would not crank for him.
it cranks ok, right?, but dont start ! and dont run,, starting takes, spark at all 4 cop coils.



I have NO fire (spark) fire is 2nd., after spark. and fire takes fuel too. at the coils/plugs. I replaced the CAMSHAFT POSITION SENSOR.....still no fire!
Bad move, if you unbolted the large alum, body CMP, do not do that. if yours has the black, sensor on that body< small, that can be changed easy.
did you just do that part? the small black part?

I have checked fuses and relays and to best of my knowledge everything is good.

How about the CRANKSHAFT POSITION SENSOR? (why pull engine, or trans, tell me>?) ever heard of an oBD2 scan tool all tools made since 1996 work.
why not use the best tool to do this, and not guess.
DTC P03xx errors. or RPM dead.>>>>
does your tacho meter move a tiny bit cranked?


does it control fire to the coils? The ECU will tell you any time the CKP or CMP misses, even 1 pulse in 10 or is dead. scan it.
yes, the PCM makes all spark and lacking timing data, guess what, no spark, but is the cam turning, maybe the last guy ran it with the poor chain screaming for help....
check compression yet that is first.

after(fuses, cams turn, no DTC errors
then compression, over 180PSI. x4 , wide open throttle.



If so I believe it is located behind the flywheel which means I will either have to pull the motor or the transmission.
i cant believe you';d do that and not scan first., why, 10+ hours labor for the want of $20 tool?

Is there any way of testing sensor before pulling motor or transmission to see if in fact the crankshaft position sensor is good/bad?
sure scan it, same in 1996 and same to 2016 same answer, you cant fix cars without a scan tool , or go broke fast.

And also if anyone else can lead me in the direction I need to be headed if I am way off course trying to diagnose the problem please don't hesitate to tell me.

sure scan it, while cranking, for 5 fulls seconds, then release key,do not turn off yet, and let the scan tool do its job. tell you why there is no spark
there are key fuses in the cab and in the engine bay finder box.
Thanks in advance.
