My car engine keeps cutting out whilst I am driving. Had the AA out a couple of times yesterday but there are no error's recorded on the car's computer and after about 15 minutes the car starts up again and is fine. It only cuts out whilst driving and only after about 20 minutes.
Name is***** goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,
This is a typical Crankshaft sensor malfunction .
Ones it gets hot will stall your engine and when the sensor (engine )
cools down will let you start again .
How to check this is the problem .
When you have a no start issue hook up scan tool and in live data crank over the engine and check the engine speed readings if shows 0 (Zero) replace the crank sensor ,
This is typical not to store a malfunction code ..
If you do have a reading of rpm then next most common issue is the fuel pump also known to freeze when hot and restart to work when cooled off get most often when the fuel tank gets below 1/4 full ..
So possible Crank sensor or fuel pump .
When no start do a fuel pump pressure test ..
