Scooby import will not start!!!!!

[P100]

Hi Guys,

Laid my 1995 import wrx up whilst I developed my new business and now I come to start it, It will not have it!
I think that the cam sensor may be at fault!
Anyone know about these, and where I can get bits near to Birmingham.??

Cheers

Roy

Does it turn over ok? fuel pump working? could well be siezed as they are often sat about empty of fuel for months/years quite a common issue especially if been run dry.

Turns over fine, we have fuel, and it has been refreshed. spark is very irregular, I think the coils are all Ok.
I have tried talking t the local dealer but he thinks I am an alien!

Crank position sensor could be the fault. have you got anyone how to do a full diagnostic check?

If so you should be able to get one from a breakers such as Grade-A subaru

Would you have a number for them steve??

It would be worth pulling the crank and cam sensors out and cleaning them - they get covered in iron filings (god only knows where from) since they are magnetic sensors.
Of course you may well need at least one new sensor, but cleaning is worth a go...
Any other sensors failing wouldn't stop the car from starting.

Have you looked at the fault codes? Connect the green under-dash connectors and turn the ignition on - watch the check engine lamp flash.

Easiest thing to do is first of all disconnect the battery for couple of hours. On the pre2000's that's the easiest way to reset the ECU. Later models it has to be done via ODBII (which is what i do via the laptop). Then try and start it but the battery must be fully charged as it will need a strong spark from having been idle for so long.

It shouldn't be the cam sensor as i had one go wrong on mine but it didn't stop it from starting.

Another possible may be the may be the MAF Sensor. Take it off, give it a clean with some meths or other solvent that evapoprates quickly and try again. If the MAF is faulty it won't start. Good luck

I'd be inclined to read the fault codes before disconnecting the battery. It sometimes takes AGES for the car to register some things as faults...

If the maf is knackered it will start but run very rough. I have seen 2 faulty cam sensors and 1 started but would not idle and the other would not start.

if you disconnect the cam position sensor the car wont start. so may be worth checking you connections.

If you don't have the correct ODBII code reading equipment or don't know how to read fault codes, and most people don't, then the easiest thing to do a reset, and anyone can do that. That can sort out a multitude of non-starting issues. If it starts after that then job done and at least you can get the car to a Scooby dealer or to someone else to fix. Prior to that make sure all your connections are secure, and if all that doesn't work there's not a lot else you can do, bar call someone out.

I know plenty of people that have had naf MAF sensors and they couldn't even get the car to fire/start at all, and with others the car idles very badly, you can't raise any revs, then it konks out. As for the cam sensor i've not heard of one stopping the car from starting at all but then again there's always one

Most scoobs will start without a MAF at all, so it can simply be unplugged as a test. The car will use the emergency speed density mode in the ECU You can use this all the time and have a MAF-less car if you are good with a hex editor, although the resolution is not good, so it doesn't make for a good daily driver...

Old Scoobs require the cam sensor so they know which plug to fire - I have seen no evidence of them switching to sparking 2 plugs in the absence of cam sync. Ones newer than 97 have wasted spark coils so don't need the camsync for sparks. That said, the Scoob trigger wheel patterns are damned weird with uneven tooth spacings and all sorts, so anything could happen.

Thanks guys,
given me alot of really useful tips.
I have ordered a new crank and cam sensor so I can start from afresh.

I have fitted a new battery today but will read whatever fault codes are in the ecu before resetting it.

I will let you know the outcome

Cheers ALL

Good luck with the Scooby Roy...look forward to hearing you started it OK
