What I want to know is at worse, what will a blown fuel pump do the engine?

How will it effect the heads? What sequence of events from the pump failure to head damage occurred?

First off, the shop is either a scam or an idiot.

Some fun facts:
- a dead fuel pump will not flood an engine
- dead fuel pump is like running out of fuel, chance of any damage with it shutting off is almost zero.
- the real worry about a dead fuel pump is when it's not flowing 100% and the MAF can't be scaled enough to add more fuel for the air intake, thus creating a lean situation and making your engine go boom. This would only happen at WOT.
- Head damage? lol. If there is detonation and part of the bottom end which blows up takes the head out as collateral damage.


Can you give us more input on what the car was doing when you drove it last.
