My 2000 mazda mpv won't crank. the fuel pump runs when you turn off the ignition. any ideas?

you may need to run a wire from a keyed ignition source that has power while cranking and running to the fuel pump relay and bypass the pcm to test wether it will run, if it runs put a more permanent wire in place.Not too sure what tests youve done but it seems that fuel is what your focusing on so a quick test is too spray engine start up the intake tube to see if the engine trys to run if it does it eliminates a lot of other potential reasons for a no start condition.Also try squeezing the fuel return line to see if the added pressure will try to make engine run.Could be time to replace fuel pump etc anyway let me know how it goes good luck with it

The heater lines that run to the back of the right rear side gets rusty and start to leak anti-freeze. There is a black cover under and above the RR tire that has to be removed so u can see.

Whatever you do, do NOT bring it to the dealer as most dealers will charge upwards of $650 for what I did in about 2 hours of work in my driveway with a 10 mm wrench and a gasket scraper.

I am not sure how technical an answer you need but basically it is as easy as removing the serpentine belt (a picture of the routing is located under the hood for future reference), loosening the bolts that hold the pump into the housing, carefully removing the remainder of the gasket (I recommend buying a gasket tool which will prevent gouging the housing while removing the gasket) placing the new gasket on the new water pump and bolting the new pump on. Route the serpentine belt and check the top off the antifreeze. Start the engine and check for leaks.

My part (which was ridiculously simple, just a pulley, bearing and PLASTIC 'impeller') cost was $60 and I was refunded $10 when I brought the bad one in.

yes it isn't that much if you buy them.they slide inside the coupler and release the line.
