Have Toyota Questions? Ask a Mechanic for Answers ASAP
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.I would start with checking the fuel pressure while the problem is occurring, normal fuel pressure needs to be right at 41 to 42 PSI and hold steady. Check this and post back with the results and we can work from there.
All you need to do to check the fuel pressure is install a fuel pressure gauge to the fuel rail service port. Unfortunately due to Justaswers policy, we are not allowed to address more then one topic in the same question. In order to get your lock question addressed you are going to need to open and new post. Not my rules but they make us stick to them.
