STI 1 Starting problem
I have a version 1 STI. Shes a poor starter some days.
Theres plenty life in her when I crank her over but shes not keen to start.
The CEL light comes on, as do the fans and she takes a good wind over before she splutters into life.
Other days she starts first turn of the key.
Was advised that it could be the coolant temp sensor located on the pipe work under the inlet manifold running from the top hose thats throwing it out.
Can anyone confirm this or are there any other ideas.
Thanks in advance

i have a sti 1 , have you checked your coil packs for cracking . replaced mine , also maybe a plug change could help , does it run lumpy on winter days ? also check your cam and crank sensors maybe clean them .. gazza

Gazza, mine runs lumpy on winter mornings until she's warmed up. Any ideas mate?

with the fans coming on it does sound like the coolant sensor. Like myblackwrx says do a search for saxonfield to get the website where it gives you information on how to read the codes and reset the ecu etc.
With the fans coming on, your car thinks it is hot so therefore it is injecting less fuel into the engine than is needed

mine is slow starting ('93 wrx), if left for a week or so then it fires straight away, fans do not come on though when i put ignition on.
I did put a post about mine last week but didn't get anywhere,
my tickover does vary sometimes when warm.
(no help I know but your not alone )

Will check the codes when I get home again and try her.
When shes hot the car runs as smooth as a new car.
I would say perhaps one in five times she has a problem starting in the mornings.
I will let you all know how I get on if I get the problem cured.
