Hello group,
My 93 Taurus has voltage to the coil pack but no spark at the spark plugs.
Someone suggested that it might be the crank position sensor. Is there any
way to test that device with a VOM? I'm new to the car and can't figure out
this ignition system. TIA

Tom

Found a disconnected wiring plug on the Crank Position Sensor module (?) on
the intake manifold. Sounds like it wants to start but doesn't. Fuel rail
is pressured up but my guage doesn't fit the test fitting so I don't know
what the pressure is. Any help would be appreciated. TIA

Retrieve your codes and repost.

I don't know what a vom is, but if you have a distributor cap, then your
ignition module that it attached to it (with some wires plugged into it) is
probably to blame. That is what tells the coil to fire. The crank position
sensor (in a distributorless ignition system) will serve this function.

If you have a crank sensor it's not that expensive. I believe ignition
modules can be tested at any reputable auto parts store; but you'll need the
special Ford tool to remove the SOB. (Boy they soak you for all they can
don't they)

Good luck.

VOM is an abbreiation for Volt-Ohm Meter.

the intake manifold. Sounds like it wants to start but doesn't. Fuel rail

is pressured up but my guage doesn't fit the test fitting so I don't know
what the pressure is. Also, which cylinder is number one? Front bank,
passenger side on right hand drive (american) Taurus SHO ?? Any help would
be appreciated. TIA

There is no way to test it. It is one of two sensors that is your problem though. Either the Crank or cam sensors. Common problem in the 89-95 Taurus SHO 3.0 and 3.2 liters.

Wires on the coil pack are a little confusing if you don't have the factory manual. Both the chilton's and Haynes are incorrect

I'm not familiar with the Taurus so I can't speak from experience. I don't
think the crank sensor would be in the intake manifold.

If you go to batauto.com and click on the technical link you can learn how
to scan your computer for codes. It's not as hard as it first looks and Ford
computers have great DIY diagnostics. It will almost certainly tell you
which sensor is unplugged or not working right.

Well, in the SHOs case that is not true. Yes you can scan for codes, but rarely will faults for the crank and cam sensors pop up.
 
The crank sensor is not in the intake, its located behind the harmonic balancer. However, the connector for it is indeed weeded in the intake.
