2002 2.7 Long crank before starting
I have a 2002 2.7 that takes a while to fire up. When starting her after sitting overnight, I have to do three short cranks (about 3-4 seconds) and she will catch the third time. Once warmed up, if I make a short stop, like for gas, she will fire right up. But if I make a longer stop, such as for groceries, she won't fire until the second crank.
Any suggestions as to where to start looking are greatly appreciated.

If that's the problem, you might be able to add a check valve closer to the engine somewhere rather than replacing the fuel pump, which is a big expensive job. A check valve anywhere in the line ought to prevent backflow.

The check valve may be failing but the fuel pump itself may be failing. The fuel pump should turn on for a few seconds when the key is turned to 'run'. I would suggest putting a fuel pressure gauge on the line in the engine compartment and verify the fuel pressure hits at least 40 - 50 psi when the key is turned to run. It sounds to me that the fuel pump may not be getting to full pressure when first turned on.

Reporting back - I replaced the pump, and now she starts right up. Really glad I decided to do the whole unit, because when I pulled the old one out I discovered the filter pad had come adrift from the pump and she's been sucking unfiltered gas. (Good thing I snagged that set of injecters Rock was clearancing out.) Fortunately, I was able to spot the both parts of the filter pad with a flash light and snag them with the four-prong grabby thing.
