K Series 7 Non Start

[JasonPollock]

Hi all, looking for some advice. During a moment of stupidness I connected my battery up the wrong way round (silly I know). Now my fuel pump isn’t priming or pumping but the car is turning over.

I’m getting the car up on stands to check for power at the pump but in the meantime is there anything obvious that I have likely fried ? The ECU and fuel pump fuses are both fine, dashboard lights up and still displays all the right info.

The car is a 1.6K mega graduate 2001 with stack dash. Many thanks

Inertia switch?

I would have expected the ECU to be very unhappy with the wrong polarity. Much more likely than any of the electro mechanical components like fuel pump.
