07 328x Cranks but doesn't start

Azzo · 03-30-2016, 07:33 PM

So I just changed the belt tensioner, belt, idler pulley and OFHG. 2007 328xi(120k)ran for a couple of days and now wont start. It cranks, the whole dash lights up including a vertical line....Not sure if anyone has experienced this....Definitely not an air issue, but is there an easy way to find out if it is related or a coincidence that the other repairs were completed and then it doesnt catch? Ran codes with an Acton OBD2 and nothing comes up...alternator/battery or fuel pump? Any ideas will be greatly appreciated...
Thanks

If you are thinking air Issue..... Then by chance did you leave a paper towel or something in any of the duct work?
Also, while cranking...... Check to see of the belt is routed properly and that you have all the pulleys turning.
Pull the air filter..... See what happens.
And since you drove it for 2 days..
.
Open the coolant reservoir.....do you see oil.
Open the oil fill side...... Do you see anything that world indicate an issue of coolant in the oil?

Sounds coincidental. Check to see if the fuel pump is operating.

Bumping a really old post, but I have the exact same symptoms after replacing the same parts. Any idea of what was the cause?

Check to see if the fuel pump is operating. __________________ A manual transmission can be set to "comfort", "sport", and "track" modes simply by the technique and speed at which you shift it; it doesn't need "modes", modes are for manumatics that try to behave like a real 3-pedal manual transmission. If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
