The crank sensor could cause many different symptoms. Personally if the voltage is in question, I'd check the wiring for rubbing and any visible damage, then move on to checking the voltage at each wire and ICM.
Well, I haven't gotten to change the Camshaft Position Sensor yet (Stepdad read the posts here, and says it'* impossible to reach - although I haven't looked under the hood yet myself - and his mechanic is unavailable as of yet) but the car gave me a new problem today.
Typically, it'* not hard at all to start his car up. Most times, it feels like the engine turns over and starts purring before I even get the key turned all the way. This morning however, was different. I first noticed a problem when I gave it the usual "quick turn" to avoid over-cranking it, but it didn't start like normal. So, I turned the key and held. It seemed to crank forever until I gave up on that try. Tried another time, and it started after a few cranks but stalled out immediately. I decided to give it one more try and it finally came alive.
When I shifted into Reverse however, the car almost acted like it wanted to stall out again. I let it sit for a minute before finally moving, and it behaved well the rest of the way to work. (30 miles, highway driving)
I'm getting ready to go to lunch now, and I'll let you guys know how it behaves then. Meanwhile, any ideas? I'll also try to find a local shop to do a quick code pull while I'm out, to see if anything new popped up this morning.
