Yes but if you loosing both spark and fuel it puts the diagnosis on a different path

Hi Chris, I merged your topics because I noticed you had duplicate posts about the same problem in different parts of the forum.
Try to keep questions about the same problem in one thread please to avoid confusion and to keep it easier for anyone trying to assist you.
Thanks :)

When this event occurs does it stop getting fuel? Have you tested it when the condition is actually happening?

We understand that the vehicle is getting fuel but when the problem actually occurs it might actually not be getting fuel. We have to assume you haven’t checked it during the time of fault. It’d be better to actually leave the fuel pressure gauge tested while the event of failure occurs.

Also have you checked any sensors for 5V ref when it is acting up?

Andy is asking because it changes the direction. Could be a whole list of things.

Thinking out loud always helps me in the process.

What's the engine size in your Toyota Chris?
I was going to have some coffee and look at a diagram for you, but it looks like there's 2 engine options. It would also be helpful to know if it is California or Federal emissions. That might sound stupid, but we get a fairly good mix of both in Massachusetts. Depending on what state you live in, you could have either. Assuming you're in the states that is...
