This reminds me about time when my SAAB wouldn't start. After some head scratching, I diagnosed it bad fuel pump (it wasn't humming). So I bought new pump and after lot's of swearing I decided to cut up the chassis from the inside to get to the pump/sender (otherwise I would need to drop the tank). Really messy job that took whole evening.
Changed the pump and .... nothing!
Then I remembered something PO told me about theft protection system...you needed to unlock the car with key fob. So I did and vroom!
Do I need to tell you that old pump was fully functional?
