So a little back story... My dad bough this thing back in 2012 and has been pretty problem free up until about the last 2 years. He didn't really drive it a whole bunch so as of right now it only has 69k miles on it.
It started running rough one day and my brother ended up changing the spark plugs and coil packs (had to do the coils cause they all broke when he removed them) and it ran fine after that. Then all of a sudden one day it wouldn't start. It'll crank all day long but would never fire up. So my dad ends up passing away and my mom gives me the car. Fist off I'll admit I'm no mechanic, but I'm a pretty good parts changer. So I do research and find that the fuel pumps go bad on these things quite often so I change the in tank fuel pump and fuel filter. Still won't start. So I bring it to a local shop that specializes in BMW's and they couldn't figure it out. They said it had the wrong spark plugs in it so they changed them, did a compression test (passed) and a spark test (all 4 cylinders getting spark) and still wouldn't start. So I brought it back to the house and I changed the HPFP and still nothing. I seems like it's getting fuel as I was able to purge a bunch out when I swapped out the HPFP. So I thought maybe the ECU was bad (saw a video on youtube). I found a company that tests them so I sent them the DME, CAS module and the key. They installed everything on their parts car and it fired right up. I'm at a loss and don't know where to go from here. I would like to get it running but I'm not far off from sending it to the junkyard. I can't just keep dumping money into it either.
So anyone have experience with these things and know what else I can check? It's not throwing any codes either.
