I own a 1991 740 8 valve with about 190000 miles.
This car has always started and been reliable but on Wednesday it would not start right up as it always has. After a few tries, it did catch and started but I've had the same problem on and off ever since. It turns over like a champ and at first I though a new timing belt might be in order although I was up to date at 150,000.
After it has proven to start, from time to time, and runs fine after it fires I am stumped as to what should be done.
My thoughts are the ignition or fuel pump, but I have no idea of how to determine what direction I should go.
Plugs and wires are new.
Fuel is a bit low (onr quarter full) but has not been a problem in the past.
Can anyone help me diagnos?
