Does not always start on first try. No codes. Holding pedal slightly open or to the floor will eventually get it going (I do not know if this has anything to do with starting the car). Gas pump sounds okay. Sometimes Pass-lock light comes on, which really messes up starting, unable to get gear out of park. Once car starts it runs very smoothly, no problems with hesitation or stalling. No guarantee after turning it off it will start up minutes later.

Hi and thanks for using 2CarPros.com. Based on your post, it sounds like you may have a fuel pressure issue. Here is what I would suggest doing first. You need to check fuel pump pressure as well as pressure drop off. Here are general directions and a video for doing that. Note: you will need a fuel pressure gauge. Most parts stores will lend you one.

I will tell you there was a technical service bulletin (TSB) related to delayed start. This is not a recall, but was noted as a problem with a resolve. Everything has been attached as pictures due to the way I had to copy it.

If you decide to check pressure, the last picture is that of the manufacturer's specifications related to the fuel pump.

I hope you find this helpful. Let me know if you have other questions.

Take care,
Joe

Thanks for your quick reply. I will look into your suggestion. Also of note: No codes. My new approach is to turn key to 'on' then wait five to ten seconds, then crank and engine starts right up every time. Could this indicate a problem with fuel pressure relay?Does this part go bad all at once or is it a gradual decline?

Hi again. That indicated a problem with fuel pressure drop off. Here is what I suggest doing. Go to the link I attached. It will take you to a page related to fuel pressure testing. Follow the directions listed.

The last picture listed above is the specs for your vehicle. When you check, make sure to pay attention to pressure drop off. I suspect that is what is happening. When you try to restart it, the pump is taking time to reprime and pressurize the system. When you cycle the key, it primes, then repressurizes. The second time you turn the key most pressure is there but again, the pump repressurizes. Thus it starts right away.

Let me know what you find or if you have other questions.

Have a good weekend,
Joe
