2003 Toyota Sequoia Q&A

2003 Toyota Sequoia Question: My sequoia will start and then stop a second or two later.

But the truck will start and run fine the second time I start it. I checked for vacuum leaks and there were none. I changed the fuel filter with no change. I pulled codes p0101 and p0102, so I changed the MAS with no change. It's now showing that all 4 oxygen sensors are bad. Would that cause it to have the starting issues? Should I change the 02 sensors because there pretty expensive? I also cleaned the throttle body which gave it a smoother idle. Any ideas? -
Answer 1
try turning the key on for few seconds then shut key off then try to start it you could be losing fuel pressure -
