Question about 2004 Chrysler PT Cruiser

1 Answer

No Start. OBDii Code P2305.

Checked wires with timing light: Cyls 1 and 4 fire normally. Cyls 2 and 3 don't fire at all. Replaced coil; same problem. Checked coil harness: Cav 1: .2 volts; Cav 2: 10.25 volts; Cav 3: zero volts. Checked PCM C2: Pin 9: .2 volts; Pin 10: zero volts. Swapped ASD relay with a known-good one. Still, no start - Cyls 2 and 3 do not fire.

    I know you don't want to hear this, but...



    I never received a reply from multiple forum posts. Best I could get was that the PCM was bad. I replaced it with a rebuilt model found on E-bay. This allowed the car to start, but it now I get a MAP sensor error. The car will still start, but requires that the ignition be turned off completely, because black smoke pours out of the exhaust. However, if I then restart it, the engine runs fine. (???) The only reasonable explanation that I have received is that Chrysler combined too many functions into the PCM and that many of these units go 'haywire' without real cause. I took the car to a Chrysler dealer and was told it needed a new PCM, a new MAP sensor, a new coil, plugs and spark wires. I told them that all of these parts were new, but they said, no, they are bad. Sure. I will sell this car and never buy another Chrysler product rather than pay the $1700 they want for this so-called 'repair'. Sad. I loved my PTC...

Since you didn't say what engine you have, I am assuming it to be a 3.7 L. Code P2305 is set for insufficient ionization of the #2 coil. 1. Inspect the spark plugs for correct application, these should have NGK platinum spark plugs installed. Inspect the plugs for any signs of misfiring, such as carbon tracking on the spark plug insulator or the coil boot. Inspect for cracked spark plugs or incorrect gap. Inspect for any kind of fouling on the spark plugs. Replace the spark plugs or the coils as needed.

2. Verify the wiring is not shorted to ground from the coils to the Powertrain Control Module (PCM).

3. Keep in mind that anything that can affect the air fuel mixture can cause this code to set. Be SURE that there are NO vacuum leaks, the injector is not at fault, etc. Moving parts one at a time (spark plug; coil; injector) to "known good" cylinders is the best way to diagnose this trouble code.

Hi,
Did the issues just start or only after some kind of car service?

I read where you checked the coil(s) but that's still what it sounds like.

I'd get a used coil(s) from a Wrecking/Salvage yard and try those - usually can be returned, whereas the dealer won't take 'em back.

I am having trouble fiquiring out which wire goes to which plug. The wires are different lengths and the correct wire length has to go specifically with the correct plug. I have the firing order dia


The firing order is 1-2-3-4-5-6
Cyl #1 is front left when looking at engine front to back
left coil pack connects to cyls. 5-2
center coil pack connects to cyls. 3-6
right coil pack connects to cyls. 4-1
It doesn't matter which connector on the coil you use just that the cylinder is connected to the proper coil pack (the coil fires both plugs at the same time, twice per each full 4 stroke cycle)

2003 Chevy Impala 3.8L #3 and #6 not firing, we replaced the coil still not firing. Husband doesn't think 2 plugs would go bad at the same time any suggestions?


may be a bad module it is under the coils I think 3 and 6 are on the same coil so that would make both cyls not fire

New head plugs and wires coil packs missing on #1 & #2 cyl


hi from uk i assume you have done all the above work correctly? and the leads from coils are correct firing order 1 3 4 2 ? CAMBELTtiming set correctly etc as you say this has happened since cyl head renewed and miss fire is on Nos 1+2 cyl's this normally suggest now after all work u have done and assume compressions are ok ? i had such a fault on a customers mini some years ago who had done exact type of job as you described this fault turned out to be the inlet manifold gasket had split between cyls inlet ports and resulted in missfire on 2 cyls adjoining on removal of manifold the gasket had been damaged whilst reassembling new gasket cured missfire which had caused weak mixtur on both cyls ie on induction more air being drawn via cracked gasket on each cyl and as your engine if injection same problem?? might be worth checking?? hope this throws some light on the problem?

I have a miss fire


Recheck the firing order; 1-6-5-4-3-2

On the distributor passenger side radiator to fire wall. 2-4-6-coil
On the distributor drivers side radiator to fire wall. 3-1-5

Cylinder passenger side radiator to fire wall. 2-4-6
Cylinder drivers side radiator to fire wall. 1-3-5

Good luck and also check the distributor cap again for proper seating.
