2006 s40 starting problems

Jaxonwolf · Feb 27th, 2021, 22:14

Help please, changed the wheel arches and engine under tray on my 2006 s40 2.0D sport had to hammer a bracket back in to place but nothing harsh, did however have to disconnect the headlights as had to pull the bumper out to get the trim part on for the under tray and forgot to disconnect the battery first, anyway, they were off for about an hour then reconnected and now the car won't start. It turns over no problem just won't fire up, had my autel maxidiag elite on and is showing loads of faults like fuel rail pressure too high and boost pressure to high as well as temperatures things like that, tried to clear them but to no avail. Also plugged it in to my vida dice same codes but can't clear them as it say the engine must be started and rev above 1500 then switch off back on and idle for 20 seconds, but as said at the beginning it won't start, battery fine as did go flat at the start trying to start the engine but recharged and still won't start, even tried bump starting it but that didn't work. Aslso last night disconnected as many sensors as I could and disconected all the plugs on the internal passenger side fuse board (I think these are the ones for the ecu and such like) put it all back together this morning and has made no change still critically I'll 🤒🤕🤮 Any advice or help would be much appreciated. Thanks in advance

Check the throttle/anti shudder valve in the air intake they are known for sticking shut stopping the engine from starting
