So my car will start first time from cold but if i drive it for more than 10 mins it just wont restart if i stop. My coolant is topped up so i dont think its overheating. If i spray an aerosol in one of the pipes leading to my manifold it will then start. Ideas?


150psi compression on each cylinder as well.

 

Coolant temp sensor will be a good place to start.

 

Do you have any idea where that would be on a 1993 ej20 engine?

 

It's on the crossover pipe next to the turbo under the inlet manifold. There is two next to each other. It's the larger one with the 2 pin plug. 17mm spanner if I remember correctly and just over £20 for the sensor.

 

I had a similar problem yesterday, was the crankshaft position sensor.

 

Is it cranking or just not starting ? If it's not cranking starter motors can be funny when hot
