Hot starting problems

[AdyB73]

Hi all,

I’m sure there will be a post on here with my related problem and would appreciate a pointer in the right direction if so.

Had a new 2.1dj engine fitted to my wagon and runs fine other than if on a long run I stop the engine for 5-10 minutes then try to start again no joy!

Engine just cranks over but doesn’t fire! Very frustrating.

Will start again once engine has cooled a little.

Please help!!

Does it smell of petrol when it won’t start?
and when it does start does it smoke ? 

check the connections and the condition of the wires onto and from the temp2 switch ( the second port on the thermostat housing that faces the wheel )

Many thanks Steve for your reply.

There is no petrol smell but will check the wires as you’ve mentioned from the thermostat.

Cheers
Ady

Fuel injection?

May not be of any use but i had the same problem. My engine was a JX though to might be totally different. (I know nothing of petrol engines) Turns out it was the stop solenoid or more so, a poor connection to it. I could get her to start by touching the connection on the solenoid directly to the pos on the battery. 

Like i said, might be of no use.

My hot start issue was starter motor, it cranked but just didn’t have the guts when hot. 2.1MV on Pierburg.
