Default 2006 Non Turbo Won't Start - Resolved

Backstory - Had a baby, parked the 2006 non turbo PT Cruiser (~160,000 km) in garage with a full tank. After about 2 months of storage, I used it to boost my Colorado, let it run for 10 minutes and turned it off. About a month or two later I went to start it again but the battery was dead (I must have left a light on or something). I set it up on a trickle charger for 2 days. Then car would turn over but no longer start. Boosting also didn't help.

Battery: I checked the battery, it holds ~12.5 volts. When trying to start it drops to ~10 volts.

Spark plugs: I changed these out to new ones and replaced the wires. Tested them after and there's a healthy spark

Fuses: I checked all of the fuses in the fuse panel, all good.

Codes: The check engine light has been coming on for about 60,000 km; but my code reader doesn't pick anything up, and the dash just displays --done-- so no codes are being sent.

Fuel: I drained about 1/2 the fuel from the tank and replaced it with 91 octane. I replaced the fuel pump. Also, car will not start with starter fluid sprayed into the air intake while someone else turns the key.

With a scanner hooked up no codes get sent. Injectors sound good and have proper resistance.

So that's where I'm at, any help or suggestions would be appreciated PS it's also had regular oil changes every 5000 km forever if that matters.

Edit -
Ultimately I replaced the fuel pump, spark plugs, water pump, timing belt, battery and it still wouldn't start. I put it for sale for parts, and when the guy came to pick it up he asked me to turn the key and the damned thing started. So ultimately I don't know what the issue was and despite turning it over a dozen times after replacing all of these parts it decided to start on its own. Couple hundred km on it now and no more ghosts.

Fuel: I drained about 1/2 the fuel from the tank and replaced it with 91 octane. Also broke the fuel line after the tank and when the key is turned on and the pump primes, fuel pumps out. Pump sounds healthy (I have not checked the pressure since I don't have a gauge and the 2006 doesn't have an easy valve to hook up to). Also, car will not start with starter fluid sprayed into the air intake while someone else turns the key.

I would suggest doing a battery load test first. The battery tends to go bad if in storage for a period of time. Its important that the battery is supporting the ignition system at the proper voltage.

After you boosted your Colorado did you start the PT Cruiser again after you turned it off?

Is that not what I just did by watching the voltage drop to ~10 while cranking? Also it won't boost. Sorry I'm a 'youtube' mechanic

Have you checked to make sure you have engine compression?

No, I don't have any gauges.
1) Would this cause a no start problem?
2) Is a valve/gasket/ring likely to wear out in a month?

if you don't get a starting condition when starter fluid into the intake, then you are NOT getting any spark to the plugs. now did you get a spark plug tester when you can crank the engine and observe it for results. if you don't get a spark, that's an indication that the crank position sensor is not sending a signal to the computer. since cars are more complex devices, it's not enough to only check for fuel pressure spark and battery voltage anymore. you should buy a subscription ALLDATAdiy.com Leading Source of Factory Automotive Repair Information for your cruiser and follow the troubleshooting steps for a cranking and no start condition

You need compression in all of your cylinders to get the engine to run properly. This might also tell you if your timing belt is aligned correctly.

PTGT03 has a good point that you need to reconfirm you have a good spark.

You might want to take off the wire going to the camshaft position sensor, trying starting it to see if the computer triggers the P0xxx code for the camshaft sensor error code.

Harbor freight has the spark plug checker for a reasonable price.

I pulled cylinder 1 plug, and used a test light and watched it arch 3/4". I didn't try the other ones since when I removed the old ones, they all had equal wear. I was worried about trying to crank it with the air intake manifold all removed and unplugged (for access to 2, 3 and 4).

I'll check out that site, assuming subscription isn't too expensive.

Right, compression good I've just assumed (yeah bad) that it's not the timing belt since it WAS running well until I turned it off the last time. It's not like the belt broke and it died. Also it almost sounds like it wants to start from time to time, and sounds completely different from when I'd heard misinstalled timing belts. Not to say that isn't the problem, I've just assumed thus far it isn't, and when I looked up replacement, I didn't want to spend 6 hours on something that wasn't the issue.

Am I looking for that code just to prove the car will even send codes?

Just to verify that the computer is triggering codes if there is a problem that it can diagnose.

Do you have an OBDII Scan Tool or just a reader?
