failed to read or able to connect. I am almost 100% certain this is due to a fully discharged battery as I have to give it a jump start 30 second jolt from a 700 Peak AMPS / 350 AMP Stanley Fatmax Jumpbox.

I am going to invest in a Drip feeding Battery Charger before my next attempt at starting the vehicle.

I am having a strong feeling that since both PCM failed a read out with the current battery state. Regardless of it's situation there is no live computer that has registered changes, resets, etc.

I would plan to rule out this notion. Does anyone have Saturn Manufacturer Technical Details of the PCM/ECU and it's full code output.

What takes place with a fully charged battery and the PCM/ECU; especially with all sorts of various changes done to a vehicle. Pre-start requirements?

For instance. Service Engine Light = Only displays for *Manufacturer list of Reasons & Corresponding Sensors, etc* -- I feel a list like this must have existed in the Saturn Corporation. I wonder if it was salvaged / saved by anybody.

It also blew White Smoke everywhere that I was able to capture on Video (including a side view from my Apartment window).

Default Re: 2001 Saturn L300 - v6 3.0 Liter - Won't stay running after a breakdown and bad...

The first two snapshots in post#94 are engine ground. Engine ground can be bare braided wire, insulated or bare wires, usually large gauge (10, 8, 6 - the lower the number the greater the number of wires to carry high current as in starting current for starters requiring anywhere from 50-150+ amps. Battery ground attaches to the chassis first with another ground cable going from chassis to engine block. That snapshot of bare wires are connected to the engine block so not need to be concerned about it being bare. The other wires, usually color coded any color except black are signal and power wires and must be insulated to prevent short circuiting to ground.

When replacing the ecm, this isn't plug n' play, requiring a relearn procedure (posted here in these forums many times). Not performing a relearn procedure results in Passlock security becoming active, disabling injectors with security flashing all the time. The relearn procedure marries the ecm to the bcm for security. The bcm has Passlock programming and detects ignition switch rotation for Passlock security. If the ignition switch is rotated and passes padlock security, the bcm sends a password to the ecm to allow injector operation. Mismatching, failure to perform a relearn procedure results in the bcm not communicating with the ecm with security triggered to prevent injector operation. Marrying the two in a relearn procedure allows normal starting without security flashing.

With many snapshots, some show the ecm loose from its mounts. Be sure its mounted as it needs to be physically bolted to the engine intake manifold/ground in order to operate. Failure to mount the ecm correctly to ground will disable ecm operation. Any incorrect reinstallation of both ecm connectors resulting in bent or damaged pins can disable ecm operation.

fdryer,

Very good to know regarding the ground wires and it being safe. This alleviates any previous concern for those wires discovered.

The pictures that showed the ECM loose from its mounts was only during disassembly & reassembly.

Default Re: 2001 Saturn L300 - v6 3.0 Liter - Won't stay running after a breakdown and bad...

9 times out of 10, engine computers rarely fail. User error from inadequate familiarity with EFI system diagnosing and troubleshooting misleads many into assuming their engine computers failed. As a rule, engineering already took into account the atmospheric conditions PCMs/ECMs suffer (subfreezing Arctic to Nevada Desert heat), extremes in humidity, dirt oil, fuel, soap, chemical solvents unapproved for engine cleaning, etc. No one is Alaska, Toronto, Wisconsin, Las Vegas or any other state have registered serious engine problems and proved it as pcm/ecm failure. If anything, why would GM/Saturn deliberately mount L300 ECMs right over the engine? The most heat would be directly over the engine while idling in stop and go traffic or next to the exhaust manifolds where more heat is generated. Within these forums, no one has ever proven without a doubt that overheating or subfreezing temps ruined their ecm. No one. On other forums, the same lack of proven ecm failure from everyday use. Yes they can fail - most likely from reconnecting the two multiple pin connectors incorrectly, probing and shorting two terminals together or applying voltage to pin in diy troubleshooting. Even static electricity can destroy electronic modules (ecm, pcm, bcm, abs, OnStar, tcm) when unknowingly probing around without considering static discharges from interacting with electronics. By most accounts, external wiring and sensors to engine computers are the main cause of erratic engine starting/running problems. The key to fixing most engine problems is having more than casual knowledge of EFI systems, mechanical fundamentals of 4-stroke engines, understanding error codes and the limits of error code interpretation that may or may not point to a faulty sensor.

With numerous posts in this thread, can we presume repairs are finished with a new alternator, battery fully charged, new spark plugs, exterior engine cleaned of oil grime buildup, all wiring are connected/none left disconnected and ready for startup? If yes, then post your observations of the instrument panel indicators when ignition is turned on before starting and any change in indicators during starting. Other than seat belt, oil, battery and brake light indications, Passlock security indications are important. With ignition on before starting, Passlock should not be flashing at all - it should be off during starting. The security indicator must be OFF to separate a Passlock disabling injectors (security flashing) from diagnosing a fuel or spark issue. With one video, the exhaust system seems to be unobstructed. A clogged, damaged catalytic converter (three in our L300s) can choke exhaust flow, interfering with engine running. If a catcon is blocking exhaust flow, this would imply the engine having difficulty in drawing in air and fuel to allow normal engine running. A constipated engine from a blocked exhaust system can be misinterpreted in many ways.

fdryer,

That is some really good statistics and information regarding the ECM. I also agree that *hopefully* the repairs will turn the engine on after I invest in a battery charging system that will allow me to recondition the starter battery that has been fully discharged since failing.

I will update this thread after this takes place sometime next month!

Thanks again for all the expertise and pointers that have gotten me as far I am!

Brandon, I left you a message over in the saturnforum while this forum was down.

Rj,

I got the message this morning. I only posted on those forums due to the heavy DDOS attacks on this forum.

I didn't appreciate the way you were talking to me Rj. There is no reason to be foul to one another.

Regarding your vehicle loss; that's not good to read and I wish you the best for your family.

As for me... I am going to die trying to fix my 2001 L300 3.0L V6

Best Regards and God Bless,

Brandon Kastning

I understand. I had sour thoughts of your intentions on this forum and I was wrong. I have experienced trolls running a forum for better than 20 years and I could not see how your continual chaos was logical or even possible.

Nevertheless, merely cleaning the oil off the engine will not fix your problems. When the L300 engine starts to blast out its gaskets, it is because of the PCV system failure. The blow-by is forcing oil out the gaskets. Even if you replace your gaskets as I just did, it will not solve the problem with leaking oil. In a short amount of time the new gaskets will likely fail. In my case the oil is gushing out near the oil pump enclosure which is what is likely drenching your alternator.

I don't know what the answer is, but I know your Oil Separator PCV Valve module has likely blown the cover off and that is where all the black gunk is coming from under and around the throttle mechanism area in your photos. There are 4 bolts you could possibly take it off without removing the upper plenium to get the Oil Separator out. Problem is, there are no replacements and the rebuild I just did sucks! If you plug the large hose entering the right side of your intake where you put all the silicone... your engine might Idle. That vacuum leak is causing the MASS AIR FLOW Sensor to misreport and hence the engine can't idle.

REWARD EXCELLENCE!

fdryer,

Do you have schematics of both the timing belt part of the engine and / or the engine gasket diagrams or physical pictures?

Rj,

Without ruling out the PCM/ECU + Fully Charged Battery + VSS; I refuse to take any hoses off at this point in my recovery.

Once the engine oil is cleaned up; once running will be easier to determine the source fault in the engine block.

Best Regards,

Brandon

There should be a timing belt replacement procedure within these forums, posted in the past and found by searching. Snapshots from members with unique camshaft locking tools (vice grips, stove bolts or plastic wire ties) instead of buying/renting a tool kit made for fixing all four camshafts in place along with a crankshaft lock when all timing marks are initially aligned prior to belt removal and replacement. I think timing is the same for all L300s from model year 2000-2005.

Engine gasket diagrams and part numbers should be available from any online GM parts distributor/dealer. Most GM online parts use GM exploded diagrams, lists with GM part numbers and nomenclature. If you cannot find info within these forums, subscribing to alldata.diy or Mitchell online for access to GM service manuals. New/used service manuals may be available on ebay.

fdryer,

Thank you for that information. If the battery charging + sensor replacements fail. I will look more into the Engine Gasket and the Timing Belt as last options.

Best Regards,
