Hey Scotty I'm working on a 03 Kia optima and it won't start. I replaced the spark plugs and the crankshaft position sensor as well as spray starting fluid into the intake manifold but it still won't start. It cranks and acts like it wants to but still doesn't what else do I need to check?
So far I have replaced the spark plugs, the crankshaft position sensor, fuel pressure regulator,and the alternator fuse. It also has a new alternator. But nothing is allowing it to start. I'm going to put a different fuel pump and distribor in it tomorrow but what else could it possibly be?
I've done all that already and still nothing
