: Excessive Crank Time - Advice Needed

My '96 Seville STS just recently began requiring considerably more crank time before it will start. Previously, it would start with just a turn of the key. It still starts, but there are times when it requires enough cranking so that you begin to wonder. This seems most problematic when cold, but it occurs when the car engine is warm also. We replaced the temperature sensor hoping it was "misleading" the computer and effecting the gas delivery to start somehow. That did nothing.
Anyone have an idea on what else it could be? Thanks in advance. Larry

The most common item causing this is the fuel pressure regulator. Pull the vacuum line off the fuel pressure regulator while the engine is idling and watch the vacuum nipple on the FPR for several minutes to see if any fuel seeps out. There should be none. The FPR is the small canister shaped device on the fuel rail that has the fuel return line exiting from it and a vacuum line going to it. It should be readily visible if you remove the silver top cover off the engine. The FPR is easy to replace as a separate item.
