Having issue with power supply regarding wire running from the crankshaft sensor. When problem happens, the van will crank but not start. On a scope, when it happens it does not show any codes, but indicates crank 0, cam 0.
The crankshaft sensor was replaced 3 weeks ago after the problem first started (with a non-Chrysler product). The mechanic at that time still had the issue of the no-start after this was done. The mechanic advised that the wire regarding the crank sensor (when the wire was disconnected from a power source) seemed to be drawing power from another wire in the harness. He placed the wire on the opposite side of the wire harness, and it started fine for 3 weeks. Recently, the van stopped again, and this time there also seemed to be a power issue with the wire connected to the crankshaft sensor. The same mechanic said he was testing the wire, and he unplugged the wire (one near exhaust manifold and another near front of engine) and it started again and has been fine. He says I have to do something, and I am wondering if that wire may be corroded, and should be replaced. The mechanic is talking of replacing the wire with another length, and soldering it to the original wire below the plug-in. Does this seem a reasonable solution. He says it may in fact be something else. What are your thoughts on this matter. Thanks for your help.
