Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
One common problem could be a leaking fuel pressure regulator so you may want to check the regulator and the fuel pressure. Pull the hose of of the regulator and see if there are any signs of fuel, install a fuel pressure gauge and monitor the fuel pressure, normal fuel pressure should be right at 31 to 42 PSI. I would also run a scan on the computer and see if there are any fault codes setting. Check these things for me and post back and we can work from there.
