where the fuel was before it went through your pump and fuel system. If
there's no air coming in, it will create a vacuum that will eventually
overpower the pump, and you won't get any fuel. I've also come across
these kinds of issues with my car, so while
it's admittedly different, the issues were close to the same...it was
Someone recently recommended grabbing the electrical schematics and checking on the grounds to make sure they aren't corroded, because a poorly grounded electrical system will wreak havoc on an ECU. Again, I could be a million miles away and dead wrong, but it's a free/cheap fix to look and clean them up.
