Olds 3.1 Starting Hard
I've got a 94' Olds Cutlas Supreme with the 3.1 engine. Lately it has had to crank over longer than usual before firing. It has over 100,000 miles on it. Could it be a filter? Or worse yet , the pump?

Have you done any diagnoses yet? It could be anything. low fuel pressuredue to a bad regulator\pump, fouled spark plugs, dirty fuel\air filter, gummed up IAC motor\throttle valve, dirty injectors, poor spark plug wires....just to name the most common problems. When was the last tune-up performed?
