Question about 2001 Mercury Mountaineer
I was driving and my 2001 Mercury Mountaineer and it stopped and would not start again. It cranks okay, but it won't start and I checked the fuses and the #19 position (25 amp) fuse in the fuse box keeps blowing the fuse that controls the PCM power diode. I have put in five fuses and everytime I turn the key on, it blows the fuse.
Clean the inside of the throtle body where the butterfly is. Also clean the idle speed control which is on the side of the throtle body. Good luck.
1) Replace EGR valve He also found a leak (with a special leak detecting gadget) at the intake manifold, so that gasket is being replaced.
2) Check your pcv valve, this on thing can cause a lot of troubleshooting. Only 3-5 dollars to buy.
