My 13 hour push to get the car done I now remember putting the old plug in to keep the drops off of my chest while I checked fitment.
Leading evidence: 'Check fitment' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check connectors' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

After I swapped my motor in (after blowing my previous one).

the first time I changed my oil in my 996, somehow I ended up with two metal drain plug gaskets.

Suggestion
Also check the connectors to make sure you don't have any bent pins.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Car won't crank after engine replacement
I have no idea where to start.
All connections are made, batter new and has a full charge.
I know it was running before the previous motor failed...
I do have a Durametric but have never used one. Fault codes- P1120, P1139, P1141
Thanks,
Bill

The ground cable to the chassis is the one I could see overlooking. Assuming that is present, I'd get out the multimeter and work your way through the system in a methodical way. Break it down into smaller segments and narrow down to the source. Unfortunately, this is a hands on exercise in electrical troubleshooting.
One random shot - is the clutch pushed all the way in?
I don't think it would result in a no crank, but there is a simple throttle body calibration you can do. It is a key on, key off, let it sit for 60 seconds, kind of deal. I'm sure it is posted somewhere on here.
Maybe this:
Ignition on for 60 seconds
Ignition off for 5 seconds
Ignition on for 15 seconds
Ignition off and throttle reset complete.
Double check that the harness that goes to the throttle is plugged firmly into the electrical connector in the throttle body? Make sure the two twist lock connectors that connect the body harness and the engine harness are plugged in correctly, fully seated and locked?

Are you using the same TB from the old engine, or the one from new engine?
Maybe swap those.
Also check the connectors to make sure you don't have any bent pins.
I've run into this before while troubleshooting.
That's not good news at all. I've been following your threads on this car and noticed you've put a tremendous amount of blood, sweat, and tears into getting this car operational. Where did the replacement engine come from? private sale or dismantler? Did the company or person give you any sort of DOA and/or warranty of any kind? I'm hoping the engine is fine and that something simple has been overlooked during the install.
It's not the engine...
Same old throttle body and wire harness, same old starter.
The starter seems no to be getting juice.
The fault codes above need to be addressed but I'm no mechanic and hate electrical trouble shooting (I suck at it)
Any chance you have a DME thing going on? Your codes are from a 7.8 DME engine but being a MY2002, the car wiring is probably set up for a 7.2 DME. On a search, I saw this swap issue in the Boxster forum and the result was the same issue you are having.
I wish I new. I'll have to double check what I plugged into the Durametric as I may have made a mistake.
The engine is a factory replacement that went into an 05 (3.6)
I'm thinking DME too. Do you have the DME from the new engine? If you are, I do not think that would working without changing out all of the immobilizer crap to match the new DME. If you are using the old DME, but the new motor needs the newer DME, that will also cause the issue.
So, it sounds like physically everything is buttoned up so i'd say were looking at something electrical here.
When you turn the key you get nothing? Not even a crank but no fire or doesn't even get to that stage?
Think were looking at:
- Immobiliser
- DME
- Starter
Do you hear the fuel pump prime when you turn the key?
Congratulations!
It usually ends up bring something like that. Hence the earlier suggestion about breaking the problem down and troubleshooting it systematically. I�ve worked in software for 25 years, and I can�t even tell you how many times bugs boil down to something simple once you get to the root cause.
FANTASTIC. Congrats. There is no better feeling than pulling something like that off. After I swapped my motor in (after blowing my previous one). I almost could not believe it started. My wife was not super happy with me when I made her come out to the cold garage in February to record it.,,,
Damn it! Came into the shop and see an 4-5 inch puddle under the car. Brand new LN drain plug's leaking. Yes I cleaned the surface...
Update and...
Correction, I put the old plug and washer in and not the LN
Runs like a champ!
I'm an idiot though. My 13 hour push to get the car done I now remember putting the old plug in to keep the drops off of my chest while I checked fitment. The next morning before putting oil in I torqued the plug to make sure and forgot that I didn't put the new LN in.
Thanks! Got the LN drain plug in today and straitened up my cocked exhaust tips (what a pain) and she purrs like a kitten then roars like a lion when I get on it! I'm so fricken stoked right now
I was just going to start a new post "I totally Get it" this is one fine machine! I waited and I worked my *** off venturing to the unknown (to me) and it was totally worth it!
I wouldn't/couldn't of done it with out the contributions so many have put into Rennlist...
You know your car better than most 996 owners do.
You've definitely seen the underside more than most people will ever see it. Ha!
What was your total cost?
Well, it sounds like your time on Rennlist was well spent, and your car has the potential for forum stardom if you ever buy a camera
Glad you're enjoying it, I hope it treats you well!
Name the shot and I'll take it (wifey has a Smart Phone) for you. Maybe a video with the GoPro (I've only used it for surfing) driving through the hills or along the coast?

Since we�re confessing...
the first time I changed my oil in my 996, somehow I ended up with two metal drain plug gaskets.
Yep, it leaked a little bit of oil...even though it was torqued properly.
