Sometimes the car will start without issues, and other times the car will crank but will not start. If the car doesn't start, then I will crank it a few times to see if it will start, and then wait 30 minutes or so and try again. Eventually it will start, cranking it a few times every 20 minutes or so. Once it starts then it will start usually every time for me until the next day (after it's been sitting all night). Most of the people I talked with say fuel pump. Any ideas?

You could have a weak fuel pump. Try this and let me know what happens.

1) From the off position, turn the key to the run position (not start) and count to 5
2) Repeat step 1 three times.
3) On the 4th time, see if it starts.

If it does, the fuel pump has a delayed prime. In that event, I would check fuel pressure.

Here is a link that shows how it is done.

Here are the manufacturer's specs for pressure.

I realize most people don't own a fuel pressure gauge, but often times, a parts store will lend or rent one to you.

Do this and let me know the results. I will then direct you on either how to replace the pump or what to check next.

Take care,
