Suffered from an intermitant starting problem a month or so ago. Had the car put on a select monitor which came up clear for both history and present modes, but the ecu was reset anyway and all was well for about 6 weeks. This week I’m having difficulties getting the car to fire although the engine is cranking over as normal.

Anyone able to make some suggestions which the select monitor doesn’t check.... originally I suspected one of crank/temp sensors. Plugs maybe ?? Cr@p fuel ??.... I’m guessing.........

I'm no expert but you could just try a different crank sensor, the ecu may not note that the sensor is faulty. Just a thought.

H,

Expensive, easy to do ??? I am a bit concerned its one of those things which is going to be difficult to pin point, especially when the select monitor says all is o.k with the items it checks. Not that i doubt the dealer network, but an intermitant problem does leave myself exposed a little to unnecessary work being carried out, let alone mechanics guessing and the car going back in again.

Wouldnt start twice today for a while and only did after repeated attempts with foot to the floor on the accelerator. Come on everyone, any ideas?, I cant be the only person whose scoob has had starting problems without being diagnosed on a select monitor..... am I ?? ! Would be good to take the car in with a armed with a little more info.

you should not be touching the accelerator on start up.

T-uk,

fully agree with you and normally I dont touch the accelerator. When the problem arises its a last resort as without it the engine just cranks over and over and over.....

It could also be the cam sensor. Just going off other threads that I've read. I'm no expert and I don't know where it's located either.

It maybe could be the throttel posision sensor.

I had starting problems when the TPS was damaged.

Thanks fellas,

A point which H raises.... does the select monitor check the various sensors are operating correctly OR the items which they check ( or possibly both )?? .... As my car came up all clear on the monitor perhaps it could be a sensor which is at fault and not an item which it is "sensing"..... if that makes sense

pob on the job

Not sure if model years come into this or if my little story will help in any way, or indeed the occurances I experienced were purely coincidental.

I had an MY97, Catalunya. From the day I got it I had starting problems. Sometimes would, sometimes wouldn't, select monitor said AOK. I was later advised NEVER to use the throttle when starting and to reset the ecu.

I did this and the start problem disappeared. I, like the person who gave me the advice could not justify the explanation. Coincidental or not, it worked for me. It costs nothing to try it, so why not give the ecu a reset and keep your right foot off the throttle when starting. I'd be interested to hear if it works for you as well.

SteveB,
I have no idea where the sensor is, surely the Subaru garage will lend you one for a while? If not then I suggest talking to an another garage like TSL or Scoobysport. They maybe more helpful. Sorry I can't be more help, nothing has been wrong with my scoob <grasping wooden table tightly>.

Alan,

Sound very similar to what I am experiencing. Just out of interest how long did it take for the engine to fire up when you had the problem. Had no hassle for about six weeks after the ecu was reset, but now it has returned. Did problems re-occur with yours with a re-set ecu ?

H,
I wish all dealers would be that helpful.... idoubt they will be though
