2 days ago, the 20 amp fuse in slot "PCM B" blew, and I replaced it with a another 20 amp fuse. I chalked it up to it possibly just a bad fuse. Now today, it happened again, just sitting idling. This time my only choice was a 25 amp fuse. 30 minutes later, I am sitting at a light and it pops again. This time I am forced to use a 30 amp fuse to get me 5 more blocks home.

Nothing else appears to be out of the ordinary. All gauges are reading normal. I'm not noticing any perfomance issues in the butt dyno, and the engine runs fine. No other electrical anomalies are known, and everything is stock.

 

Ok, nevermind

How nice of Airtex to include 5 miles of extra wire with the new fuel pumps! Apparently, the wires had drooped down to the side of the tank. Yea, guess which side of the tank? The side where the driveshaft is at. They drooped right next to the u-joint bolts. Which of course chewed right through the pump wires themselves. Ugh, lesson learned! ZIPTIE the extra length of wire up onto the fuel lines!

 

That would do it! Glad it was something easy!
