First time and first post on this forum, so just wanted to extend a warm hello from Australia.
I have a strange problem with wrx and hoping someone could help. I own a MY99 and from yesterday onwards have had some really strange problems.
Yesterday when I tried to start my car (cold start), it would crank continuously without starting. When i tried to see if there was spark (taking out the ignition lead), there seemed to be spark, then the car started. Leaving it running for about 20 seconds, before it shut off again.
When i tried to start it again, it didnt work. Checked spark again and to my surprise there was no spark. Left it there for about 3 hours and there was still no spark. Checked spark properly with meter and there was definitely no spark.
This morning when i woke up and started it again, it worked okay without any problems. Left the car running for 20 minutes, shut off and cranked multiple times without problems. I have no idea what is going on nor have any clue as to what what could be causing the issue. Has anyone been in the same situation?
Some of things I've been thinking about include:
- Factory Brant Immobiliser: it seems to be powering the car okay, power is provided to car (can crank engine and hear power and fuel pump whind)
- Fuel pump: refer to above
- Ignition lead?
- Ignition coil?
- Spark plugs
NOTE: - pretty certain these should be okay, if it fails it wouldn't be temperamental right? (i.e. if it didn't work, it wouldn't work at all, it wouldn't be inconsistent...?)
- Crank angle sensor? (don't these generally malfunction on warm->hot starts?) the car didnt crank on cold start initially so wouldn't that rule out crank angle sensor?
Not sure if anyone has been in a simlar situation, but if anyone has, any light would be greatly appreciated.
