2009 Aston martin, clutch and pressure plate was replaced by a shop, after the replacement car wont start, it crank already but it wont start, no fire on the coil nor injection, but car crank, before the replacement of the clutch and pressure plate, car was starting. i have tried to find out by them if they have accidentally got something wrong done while doing the installation but they could not say anything...

well could someone help with the location of th crank and cam sensors

 

Did they change the flywheel? If it was not installed correctly the car doesn't know crankshaft position and you will have those symptoms.

 

well they said they only change pressure plate and disc, I have tried my best to get access to schematic which shows where the crank sensor could be, I don’t know if it is on the bell housing sensing the flex plate or it is inside the engine or the pulley front area, I don’t know, this car their schematics are hard to find.

but am very grateful for taking your time to read my post. Thank you, if you have some informations to share, I will welcome it.

please are you a tech guy on this particular make

 

Crankshaft speed sensor in at the back side of the engine at the bottom center.

 

so it means It not closure to where the bell housing is, some cars have theirs in the engine while some have it at the front of the front pulley and others too on the bell housing where the flywheel is… do you think where it is now, removal of the transmission could have had effect on it, even though they re saying no fault code when the engine crank,

 

i would be all over my OBDII reader searching for codes, before even thinking about getting under the car.

 

How did you pick up the car after the clutch service? Is it still at the shop?

Also if it's an ASM there is a clutch position sensor as well.

I have a 2009 Vantage Workshop manual. It's 115 meg file if you have a way to receive it I could send it to you. They are also on line

 

I have am yet to get the car, it will need to be tow, because it is not starting, I asked several
questions from where the car is and all the information am discussing here were provided base on the questions I asked , so personally am yet to have the car tow to me, for scan report and live data analysis,

 

Did you ever get this resolved?

 

If It's an ASM / Sportshift gearbox, it's necessary to run the adaption procedure after clutch change in order to teach the new clutch kiss point.

 

Might this be as simple as the switch under the brake pedal? I had a similar problem with the switch under the clutch pedal in a 6MT car some years ago, which would prevent it starting.
