Technical Sei Warm start issue.........kind of!!

[Freshprince78]

Hi there, im new so hi

Ive got a starting issue with a 1999 Seicento.

It starts cold after 2 or 3 attempts but wont start when warmed up.

ive read most of the posts re: warm starts but as mine struggles to start 1st time when cold I wondered if anyone has any ideas about how to fix it.

when its cold it turns, fires then starts, when warm it keeps turning but doesnt fire or start?
Ive changed the spark plugs, ive drained the cooling system and put fresh coolant & water in, ive cleaned and rubbed down the earth cable next to the alternator but still have the same issue?

Im going to charge the battery but dont think that is the issue.

Has anyone any suggestions what to change now?

Thanks

i would check the temperature sensor first.. and check the wires to it..

Ive ordered the coolant temp sensor, the one that sits on top of the cylinder head, is that the correct one?

1999 sei, i think is SPi. If so, then is the one screwed into the inlet manifold.

OK ive changed the temp sensor to the ECU and still the same issue, starts after 3 turns when cold, wont start at all when warm!!
anyone any idea where to look now?
any help greatly appreciated.

It seems to tick over fine until warm, the fan doesnt kick in then it cuts out and wont re-start, the fuse for the fan is ok

I would clean up the crank sensor.

I've got a spare crank sensor if you need it. The code on mine is SEN8D3
