Engine starts but stops immediately

Welcome to 2CarPros.

This can be caused by a few things. First, take a look at this link:

Next, I would suggest checking for engine vacuum leaks. A leak can do this too. Here is a video that shows how it is done:

Also, a fuel pressure regulator can cause too much fuel to enter the engine which can do this too. You may want to test fuel pressure and the regulator. Here is a link that shows how it is done:

Here are the fuel pressure specifications for your vehicle:

Key On Engine Off 35 - 45 psi
Key On Engine Running 27-37 psi
Engine Running Vacuum Hose Disconnected From Pressure Regulator 40 - 45 psi

Start with that and let me know what you find. Let me know if you have other questions or need help.

Take care,
Joe

Hi, emailed you a couple of weeks ago, thank you. My problem is my vehicle listed above ll model, when I first start it, it shuts off off, then I start it again and just rev the gas pedal for a bit maybe two minutes, then it starts to idle and run fine. It is just the initial first start up. I was thinking we may need to change the vacuum lines but can't seem to get a good diagram online. My manual says to check the vacuum hose near the intake manifold. Is there any way you could guide me on this and help me get a good diagram, on the vacuum hoses for my vehicle? Thank you

Hello thanks for using 2CarPros.

Hello it seems your idle control is not working properly. check attached files for complete trouble shooting.(fig 1,2,3) and fig 4 for vacuum diagram.
