Hi guys, new to the forum but have visited before as solely an observer. Nice to meet you all. I'm Rob from the North East of England and aside from it being a non runner currently, I have a nice ol' comfy 2009 Saab 9-3 Estate (or Wagon, depending on what part of the world you are from).
Anyway, so as I've observed while trying to find a solution to correcting the problem with my car and this issue I am having, is evidently a recurring common issue.
It all started with an intermittent issue of the car stalling out whilst driving. This happened often when turning round corners. (it did happen whilst travelling ahead too).
I managed to bypass this and ignore the issue while driving by either stopping, locking the car, waiting and then unlocking the car and she would fire right back up OR IGNITION off and bumping the car whilst still in motion.
I was able to park the car outside my house and it was left for a while before I had intentions of getting in and driving again. I got in, turned the key, no fuel pump sound and a traction control error.
What I have done, is I have attempted to start the car manually by jumping the pins of the relay that operates the fuel pump, I turned the key to position 2 and cranked the engine with the starter, from inside the fuse box under the bonnet. (I also tried to look for the fuel pump fuse in front of the battery, but it's not there on my car). Anyway, no joy from that. The starter and the fuel pump BOTH operate when jumped the pins from the relay. I have had a multimeter on said pins of both the relay plug from the fuel pump and the starter. I'm getting the standard reading from the constant live side of the fuel pump relay plug, but I'm only getting around 1.25/1.30V reading from the switching side when I turn the key. (possibly a side effect of the true issue). Same from the starter relay.
I've also tried to Jump pins 1&13 and 2&14 from the ABS module to see if she would start, to no avail. (I did this with the battery connected so if I need to do this with the power disconnected, then I haven't actually tried that yet).
I then moved on to the big daddy of them all; the ECU in front of the driver's side wheel arch (RHD) (what genius decided that would be an excellent place? Like sh*t i'm sure it would be easier to relocate to avoid masses of wiring needed to route around the engine bay and I'm sure it's probably likely to cut out half of the causes of the issues with broken wires, but hey I'm not engineer...).
ANYWAY, I've managed to remove the ECU and it was completely soaked. The smaller block connector had been opened before as it had a badly bodged wire. I then rectified said bodge, thinking it could've been the issue. (I wish).
The larger block connector was also soaked right through.
I've cleaned the exterior of the ECU and have dried it out over the last 48 hours on a warm radiator. (If there was any water ingress then I'm screwed as the damage was already probably done and I finally crucified it when I dried it out. During this time, I also took the time to charge the battery).
I have NOT tried to use the OBDII to diagnose any potential issues recorded on the ECU as I do not have access currently to a Diagnostics tool (recent house move and it got left behind at my mother's).
If ANYONE has any other suggestions, please can you suggest them, as I am now at a total loss and my brain has turned into some grey matter mush!!
Thanks so much in advance, I look forward to speaking with you.
