Quick and Dirty:
Already replaced...
Fuel tank
Fuel pump
Fuel pressure regulator
Fuel Filter
Ignition switch
Spark plugs
Should I replace...
Coolant temperature sensor??
Crank position sensor??
Fuel pump relay??
Fuel pump, FPR, filter AGAIN?? Defective?? Only the FPR is aftermarket from RockAuto
Injectors?? Doubtful because oil does not smell like gas
Longer
My 1990 325i (5 spd, 4 dr, 218k) does not start reliably. This car sat for about 5 years, and I'm trying to restore it to its former glory. Before it became my daily driver, I siphoned the old gas out and changed the fuel filter (in addition to oil, t belt, etc). Apparently, that wasn't good enough because the car kept losing power above 2.5K RPM and I had to replace my fuel tank, fuel pump, and fuel filter (again). Now the car does not lose power at all...it runs awesome all the way to 5K RPM...but it doesn't start on the first try about 10% of the time. I have to crank the key for a good 7 seconds sometimes (at which point I stop to prevent burning out the starter). Then the car almost immediately fires on the second or third attempt. Where should I start with this??
