08 Toyota Camry 2AZ-FE R9K Tuned
Quite interesting. I know nor do I not care that this would not apply to older Toyota's but some of that info could explain Gen 5/6 Hard Start Issues that have been occurring lately.in the link below is all the information you want to know about the history of the Toyota fuel pump recall. The fuel pump is made by Denso in Japan. Check out the "Chronology of Principal Events" in the document below for the history of what happened.
One interesting thing is that they don't have a solution yet.
