Default Turns over fine, wont start.

So at my new place the parking lots are kinda really unlevel. Last night I parked my car and it's the drivers side is below the passengers (level wise) by a solid amount. Car will turn over beautifully but won't start. Is this because of the gas tank being very unlevel? Especially since it's on the passengers side and higher. Has a good amount of gas in the tank, more than half full. Any ideas or experiences like this? Thanks guys!

Based on your previous posts it looks like you've been working on the car lately. Make sure your spark wire connector isn't coming apart at the junction clip. The clip is plastic and can start to not hold together tightly. This wire runs across the top of the firewall. Just search for it and you'll find the schematic. It could be your culprit. No spark - no start......

Try tapping the Fuel pump relay with the handle of a screwdriver. Might be that too.
Just a thought.

You need to narrow it down to what's keeping it from starting... no spark, no fuel, no injector pulse, or (in extreme cases) no compression.

I was battling a non start for the longest time and it turned out to be the alarm. Worth trying to jumper it if you have one.

Do you have the "tach bounce?"

Turned the key sunday morning and whola, started right up. Must've just been "one of those days"! Drove Sunday and today. Started no problem, ran beautifully. Kinda just has a mind of its own!

Well guess what.. wouldn't start last night after work. Same problem. I have no tach bounce. Does turn over just fine. Checked connections, everything seems to be fine? It is 27 degrees outside though.

Will try the speed and reference trick. Having someone bring me a 10mm ratchet with a bunch of extensions over to my car after work.

No tach bounce. Any suggestions for the culprit?

Could be the fuel pump. Also check to physically make sure there is gas in the tank. The float could be mis-measuring. Never had this problem on a Porsche, but did on a BMW 330. Needle read half tank but it was empty.

No Tach Bounce usually means either:

Bad Speed Sensor, but those are a pain to get to.

or

if you have OEM alarm? Jump it as per Clark's.

There might be more things to check, but start with those two, alarm first if you have it.

Update Update Update!

Found the culprit! ^^^

I worked on my car in the parking lot at work today (where I left it because it refused to start). Tried again to start it because it was warm today and above freezing. No luck. Pulled the sensor closer to the front. It had a little grease on it, cleaned it and put it back in. Pulled the one closer to the rear of the car. A little beat up.. It's the one picture. Put it back in, wouldn't start. Played with the distance of it for about 15 minutes and surprise, it started. Drove it home, parked it in the garage, and away for the season it goes. New speed & reference sensors come Monday and we'll be on sometime soon!

Thanks for the help guys!

That sensor could be dead, bad reference sensors can fail intermittently, I bet that's the trouble

Broken solder joint on the DME or DME relay?

did you guys read my update? 😂

When I put the sensor back in after doing the clutch job it was too close the the flywheel and I guess scratched it. because it was scratched it was not at the set hight anymore and wouldn't read. I played with the hight for a bit and going back and forth trying to start it and finally it started after a while.
