Success then failure...

[LT]

All, H20 pump in, thermostat in, timing belt on new hoses, sweet! Started right up and running way cool! Had to burp the system a couple of times for temp to stabilize.....then !#%* car began to act up again. After starting and running fine 6+ times, now intermittently decides to take multiple start attempts before starting. When it does start the tach does not work until speed is up then all is fine. Prior to performing work I disconnected only the battery...I gapped the crank position sensor per procedure with a garden variety feeler gauge. Have yet to run codes. Have day off tomorrow would like to finish the job.

Check the codes see what comes up. Certainly sound like crank sensor. Is the sensor new? Could it have been bumped or had coolant spilled over it?

Hmmmm... I wouldn't be surprised if you find a 212 and/or 214 code in memory. Did you replace the CID (Cylinder Identification -- also known as CMP - Camshaft Postiton) sensor? That is generally responsible for hard starting. Although where you're also seeing tach problems even with a new CPS/PIP/CKP (all these damn sensors have so many ways to refer to them now...), I'd suspect a DIS (aka ICM) issue, possibly a ground incontinuity between the DIS and the chassis, a loose connector on the DIS, or less likely an intermittent DIS failure.

Re: the crank sensor gap

While the book specifies a .030 gap for this adjustment, it is not likely to be critical as long as the vane on the timin pulley is not making phisical conact with any element of the sensor.

The CKP is a Hall-effect style sensor. It relies on the interruption of a magnetic field to order to cause a change of state of the output. As long as it isn't rubbing, it should be fine.
