So my 2000 Dodge Grand Caravan has been having an intermittent no crank/no start problem. It started as intermittent, but as of a couple days ago it seems permanent. The PO replaced the starter about 3 times. I cleaned the non existent corrosion off the power distribution block. I also replaced the ignition switch with a standard ignition product from oreilies that seemed to fix it for a couple of days. I have swapped the starter and asd relays with things like the horn or the blower motor with no change. I can jumper the starter from at the relay and at the starter itself and it spins the engine over just fine, even with the key on however, the engine will not kick into life. I have checked all the fuses and they are good, even the fuses under the dash. Everything on the ignition switch side of the circuit seems to be fine, but everything the computer controls doesn't seem to be turning on. I can't hear the fuel pump,the computer is not grounding the start relay, and the biggest telltale sign is the CEL IS NOT coming on. Which is telling me that either a fuse that powers the ecm is blown, or the ecm itself is fried. Is there a fuse that dodge labeled as something meaningless like the power windows but actually controls the entire fuel injection system like the ASD fuse on my 94 dodge ram? If I can't find a blown fuse is there a way to test the ecm before dropping $150 to have it rebuilt?
