Hey everyone; been having a few problems with this car since I bought it. But I've been powering through them, and most recently had to replace my alternator. After replacing it, it worked great and drove great. A couple weeks later it started having a slight knock to it but no check engine or any kind of indication something was wrong besides that. Then a couple weeks ago I see im due for an oil change, a little late but nothing to worry about. I start the car and drive about a quarter mile and it dies on me. Pushed it to the side of the road, tried a few times to start it and it would just crank but not start. Battery and alternator check out, everything seems ok. Try again about an hour later and it works, a little sluggish but it got me home. After letting it sit and trying to diagnose it I start it up and drive it about a quarter mile again and it dies. This time the oil light comes on, engine service required, alarm service required and immobolizer. FML. So I get it home, chnage the oil, oil light goes off, Immobolizer no longer showers. Engine service still shows, thinking it could be my MAF sensor, I clean that. Nothing improves, so I throw in a obdII scanner and it gives me those three codes. P0432 P0422 and P0103. Now whenever I turn the key, the first time it will start then shut down after a second. From then on it will crank but not start and there is a smell of fuel whenever I try to start the car. I was thinking maybe 02 sensors, a vacuum leak, or something with my fuel pump maybe? Any help would be appreciated. Also there is this; I dont know too much about cars or volvos for that matter, so keeping that in mind... I found this and don't know why its wet or if the crack is ok.
