I just bought a Saab 900 from a friend who didn't maintain it well. Right now the problem is that it won't start. A buddy and me got it working right after I bought it, but I didn't notice the gas gauge was broken and ran it dry. Then I flooded the engine (after running all of the junk crap from the bottom of the tank through it as I was running it dry). So compound problem: junk in the tubes/engine and flooding.
I'm pretty sure I got the junk out by removing the plugs and turning it over for 20-30 secs. Did this a few times, both with the pump relay in and out, so the junk should be out of the engine and out of the lines. Last things I put in the tank were ~ 2gals premium and 2 bottles of dry gas. I've had it come close to holding a start a few times now, but like this guy (http://www.saabcentral.com/forums/showthread.php?t=25606&highlight=flood+engine) it just didn't want to stay lit.
Currently the plugs are out and sitting on my desk, and the battery was getting a trickle charge.
Next on my list of stuff to do:
Try to start it normally (I predict it will flood, as this is what has happened each time. It turns over, gets compression, and starts to spark, then tries to get up to idle and dies - this has happened around 5 or 6 times now.)
My buddy suggested disconnecting the "5th injector." apparently this was disconnected when we got the car, I remember a plug being disconnected but I don't remember which one it was. I know I should get a haynes book, but right now the funds aren't there (everything's going towards getting the car running) - are there diagrams or illustrations available online?
From the post linked above, after that I'll be trying:
The ignition module (is it properly connected)
Firing order (looks right to me - I already checked - but to make sure, what tool do I use? [i.e. looking at the cables it all looks correct, and I don't think they've been switched since it started correctly last time.])
Cold Start injector/valve (no clue how to check this)
Lastly, a clue to all of this perhaps: the girl I bought it from said anytime you pushed on the throttle too much it flooded. Any ideas what might be causing this?
Thanks for any help.
