Sometimes when I start my 89 525i it will crank, crank, crank for longer than normal (4 seconds or so) then start. Usually, it's about .5-1 second and start. I just put in new wires, plugs, cap, rotor, the whole shibang and still happened last night. Doesn't happen alot, but still there. BMW said the starter is prolly going bad.. ugh.
Checked the archive and investigated a few other things, but still no luck. The battery has plenty of power, and the starter (and engine) turn over fine. no funny noises or anything. it took a minute or so to get the car started early yesterday, but once it was fired up, it was fine (no stumbling or misfiring). The car started up within only a few seconds later that afternoon (engine was still relatively warm, or at least not cold yet. coolant temp was above the blue). I have checked the distributor cap and rotor and spark plugs. plugs look fine. Cap and rotor need to be replaced, but don't seem to be bad enough to keep the car from starting seeing as it ran fine yesterday. I tried to test a spark plug by removing it from the head and pluging it in to the boot and having someone try to start the engine while i grounded out a side of the spark plug. I didn't see any spark...
Things that i think it could be are either the rotor/cap, the coil, or perhaps a fuel pump relay or the pump itself.
what are ways that i can test these things? anyone have any other ideas as to what it could be?
