Hesitation starting first time in the Morning?

Hi,

This could be the result of a few things. For example, there could be a leaking injector allowing fuel pressure to drop off after it sits, it could be ready for a tune up at this point and so on.

Once it starts, do you have any problems? If not, try this and let me know the results.

1) Turn the key from off to the run position (engine off) and count to 5.

2) Turn the key off and repeat step 1 a total of 4 times.

3) On the 5th try, see if it starts normally.

Try this and let me know the results. Also, let me know if you have replaced spark plugs yet. They are due at approximately 100,000 miles, so we are close if you haven't.

Take care,

Joe

Hi,

Yes. With your foot off the brake pedal, push the start button (maybe twice) to put it into the run mode.

Let me know.

Hi,

Was that an improvement or not? If it was, we need to do a leak down test on the fuel system. If it did improve, that tells me cycling the ignition on and off has allowed the pressure to build up again.

Take a look through this link. It explains how to test pressure and fuel pressure drop off.

Let me know if that is something you feel comfortable performing. You will need a fuel pressure gauge, but most parts stores will lend one to you. Also, note that this vehicle has two fuel pumps. One is located in the fuel tank and produced a lower pressure. It functions more as a lift pump to get the fuel moving.

Once it makes its way to the engine, it reaches a high-pressure fuel pump. That one will require a special gauge for testing, or it should be done using a scan tool that can communicate with the vehicle.

Let me know.

Hi,

That is what I would recommend doing. See if the fuel pump is within the manufacturer's pressure specifications and if it drops pressure too quickly.

I attached the specifications below for you. Note the extreme pressure from the high-pressure pump. You can't use a traditional fuel pressure gauge with that. It should be done with a scan tool.

Let me know.
