Question about 1998 Dodge Neon
Ck'd fuel pressure ok. ck'd ignition for spark and had spark on #2 and #3 cyl., had NO SPARK on #1 and #4 cyl. replaced coil pack, still no spark, reinstalled old coil pack. Checked for pulse at coil harness, 2 & 3 had pulse when cranking but no pulse at 1 & 4. Checked wires from coil harness to PCM, NO OPENS. replaced PCM with rebuilt unit from auto computer exchange, ck'd and no spark on any cyl. reinstalled old PCM and got spark again for cyl. 2 & 3. Sent back rebuilt PCM for exchange. While waiting for new PCM, reinstalled old PCM and changed out crank sensor and ck'd, still spark at 2 & 3 nothing at 1 & 4. Checked wires from crank sensor to PCM, NO OPENS.
Received exchange PCM and installed, still have same problem, no spark at 1 and 4, good spark on 2 and 3.
Was told to check out cam sensor but thought cam sensor was related to injector timing mainly. ????
Need some expert help if anyone has a solution or further diagnostics.
Can't afford to keep throwing parts at it. Please respond if you have any ideas or email dougg53 @yahoo.com. Thanks
SOURCE: car died and will not restart
Have you had your Battery,starter and alternator checked? if starter or alternator bad will drain battery. If battery is bad will damage alternator over period of time. If not changed. Also check your battery cables, make sure your +/- is without corrosion. Possible voltage regulator.Hope this helps..

Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition
coil or injectors getting cracked or dirty and needs to be cleaned.
confirm the problem, the basic troubleshooting is required.
