Broken down 🤬 Open to suggestions Just finished an ace track day at Oulton Park, car didnt miss a beat. About 20mins into the drive home the car lost power stalled and wouldnt restart. Gave it 10 mins and tried again and ran fine for another 20mins. Died again so Called the breakdown company. Oil level looks fine, no EML and no codes to be read via OBD Tuner on laptop. Engine temp has been normal. Didnt get wet all day. Any suggestions? Its a supercharged NA

MAP sensor would be the first thing to try

Fez had an issue to do with fuel... I recall it occured when the tank was low and it was hot.  Running low?

[Chris P Duck]

28 litres of fuel and will be a lot cooler now than it was on track. Can hear fuel pump priming as usual. No way to test MAP sensor by the side of the road without tools / multimeter I assume?

Crank and cam sensors would both cause the car to turn endlessly without firing... both seated correctly and wiring look OK?

Would need nice circled images (idiots guide) to know where to look... Wouldnt they both set fault codes though?

Can you run a short OBD log to see if the TMAP is functioning as it should?

Mines a Turbo and don't know the Z22SE but read a few articles and apparently, there is no cam sensor on a Z22SE but there is a Crank sensor located behind the oil filter, below the inlet manifold, behind the starter motor

 

I'm sure I recall cases of crank sensor failure without codes.

 

Hope you get it sorted.

Do you have breakdown? If not do you need me to come help?

[Chris P Duck]

Home now, started again once breakdown van turned up so he followed me the 0.6 miles to my house. Will investigate at the weekend

[FLD]

At least you're home.

[Chris P Duck]

At least you're home.

Offer of help is very much appreciated anyway 👍

Has anything been done to the car this winter? (maintenance, upgrades etc)

Only suspension related and a normal service (oil, plugs filters)

Had this with the crank sensor on a couple of Alfa they started fine when cold but just turned over if hot until it cooled off ?

This!

 

I had the same thing with mine over xmas. Car just died, wouldnt restart for awhile and then when it did it wouldnt idle but would run like crap if rev'd over 1500rpm (enough to drive it back into the garage after recovery). Joe came to the rescue with a bunch of sensors and it turned out to be the MAP sensor, running perfectly after it was swapped.

 

This is the one to try first because you can swap it in a few mins. Its at the top of the intake manifold and held in with one bolt. Much easier than the other sensors to get to so start with the easiest!

Could you not have pushed it?

 

Glad you made it home anyway

I thought the same, but wasn't impertinent enough to type it.
