ever see the car run good before, or just died dead? out of the blue?>
cranks ok or not. (grrrr grrrrr sound, or not)_ called cranking the crank shaft. fast.
cranks starter motor fast and not starting?
or never cranks the starter motor at all silent starter?????
2002 Dodge Neon, with secret motor under the hood.
2.0 liter engine, 132HP. or he 2.4L I an not guess engines ever
SOHC or DOHC engine were there, both an OPTION./
VIN F or VIN C engine they are not the same.
the twin cam engine DOHC is
interference engine that must not be timed wrong ever. I'm told both are but my test is most strict ask.
"Power on no 1 and 2 coil plug wires but none on no 3"
does power mean HV spark or the primary side has power
yes it does if fuse is not blown, all fuses good is first. ok , all.
ASD sends 12vdc to the spark coils.

Looks like it is one tooth out on timing.( the cam belt wrong?)
really? no engine PCM likes that, it can bend valves on some engines. never time a cam wrong .or boom happens.
the non COP engine (1 coil pack)
has just 1 coil pack with 4 HV terminals
there is no spark timing at all, (is cmp + ckp)_
cam wrong wrecks cam time and spark both.
CMP sensors and CKP sensors set spark timing, and are fixed in the case of crank. (the cam CMP sensor will be off if belt is timed wrong.
WASTED SPARK if you replaced the 4 spark wires 1 by 1,
there would be no mixup and spark would be good.
Coil No. 1 fires cylinders 1 and 4. Coil No. 2 fires cylinders Nos. 2 and 3.
if you mix up the 4 wires HV it will not run
mixing 1 to 4 works, but the wires are too short
mixing 2 and 3 works, same deal
mixing 1 to 2 or 4 to 3 is FAIL
see why> firing order wrong. PCM does the older not you.
if you wreck the order it will not run.
4COPS can mix all you what so there I did both engines
the cam belt is a 60,000 service, if skipped the DOHC blows up.
piston hits valves and boom valves bent and heads a train wreck from H3LL. and compression not 200psi but 5. BOOM.
never skip cam belt service, did you?
did you drive it till it DIED? not told
or just doing normal service now.?
history matters, next time ask for help before going broke on part not needed
btw the quad spark pack the best ones are marked clear as day
1,2,3,4 at HV terms
and engine is
cambelt 1,2,3,4 , trans.
to test for spark only unplug 1 plug or get wrong results on 4 in 1 pack.
the 4cop spark coils test them any why you want even all at once.
always assume interference or go broke fast
and some engine heads milled become interference and you can't know that standing far away 3 feet.
there are some DOHC engines that are free running
means cam stalled and crank spins and zero damage
if you bought a dead car(my act for years) we check compression first not buy tons of parts praying for a dead engine to run.
even engines on a pallet used. I test them.
time the cam per the service manual
if you'd tell what engine was there I'd post it.
note the better coil pack
to test # 2 or 3 both spark plugs 2 and 3 must be connected
and shells ground to the engine block or both fail.
and both spark wires can not be open, mag wire is best.
this is called wasted spark and is only 2 coils if you look closer
