Chris,

I'm running into exactly the same thing!

My ECU's is working perfectly, 'cuz I tried it in another Montero, and the relay clicks on Run and Start, but I get no voltage to the pump.

I pulled out the pump, and hotwired it, and it runs OK. Tested continuity from the relay to the pump, and it's OK, too.

Maybe the relay died, but I can't seem to find one at the P&P. Autozone has one? Yikes! $125 is kinda steep. If I can't find one cheaper, I just might re-wire two Bosch relays and pray that it'll work. Keep us posted if you find out what's wrong.

Thanx,
Chris
