Posting here also to hit a larger audience:
lately my 01 Ex. has started exhibiting a strange cranking issue. This may be kinda lengthy.
A couple months ago during a tow trip (24' enclosed car hauler), I applied a little too much power during an up hill incline and set some kind of code. When I got home and read the code it pointed to the IPC having too much put to it. Too much throttle with too much load or something like that, so I then cleared the code. Since then:
1. First, the truck, once started seems to run perfectly.
2. Two known good Interstate batteries.
3. After it sits for a few days unatended, it is very slow to crank as though there's something draining the batteries. Can't imagine what it could be.
4. Drag out my battery charger and put it on trickle. Even after a couple days of that, it still cranks slower than its normal fast cranking.
5. During these slow cranking episodes the engine wont fire, which is not normal. Before all this, when sitting out in MI winters a few years ago, it would crank really slow but would eventually fire to life. Here in TN it's not cold enough to cause engine not to fire during slower cranking.
6. This morning for example, the batteries have been on trickle charge for a few days, metered the batteries and they measured 12.77. Still cranked slower than normal and took longer than normal fire to life. Drove a few miles to the dump to get rid of trash, drove back home shut the truck off, and it cranked very fast like normal, fired to life almost instantly.
7. Tomorrow morning I'll try and start it without the charger hooked up and see what it cranks and fires like. I'll measure them first to see what the voltage is. They measured 12.78 when I got home and it cranked super fast.
Any ideas out there??
