Hiya all,

I have a 1998 Grand Voyager SE w/2000 model eng/trans/computer. This van was a running and driving van in a local medical transport fleet for many years, and was purchased about two years ago by one of the fleet drivers for his own personal vehicle. I've been servicing it ever since.

Recently, he's had issues with hard-starting, and then eventually, it just wouldn't start at all. Had it towed in and pulled the codes to find P1391 resident in the computer (CMP/CKP sensor intermittent signal). Both sensors where replaced, engine started, and code was resolved. However, car now dies when attempting to shift into drive, has poor idle quality, and after trying to shift into drive more than twice, it will simply not start back up until the CKP sensor has been disconnected and then reconnected.

I would also like to add that we have replaced the ignition coil pack. No other codes are present. SES/MIL light comes on and off at random.

We have toyed with adjusting the distance of the CKP sensor from the tone ring. Any of the adjustment distances where the car will still run, it still will not run in drive, with the exception of when the tone ring is ACTUALLY PHYSICALLY CONTACTING the sensor. That only worked one time.

Any suggestions?
