Hi, it's a '92 Pontiac Grand Prix LE 3.1 V6, auto, air, 4dor in an
elegant off white.
The snificuntuther drives it home fine last night and calls up to say
"she no start" this afternoon. It's 34 degrees out. It cranks and you
can smell a little gas. It doesn't even pretend to fire. It has a new
serpentine belt. I pull a couple of plugs and hold them up to the
block. No spark. I check the fuses, which are fine. I play my trump
card and jiggle the wires. I read up a bit and can't figure out where
the CAS sensor is located. This is the first and cheapest thing to
replace, right? The engine is in sideways with the pulley end towards
the passenger side. There's no old style distributor, just what looks
like a two tier rack that purportedly contains 3 coils, an ignition
module plus the plug wires. Is this correct?
In my way of looking at things, the rack is facing the front of the
car and is on the right side of the block so if you have directions
please consider being specific as repair on newer cars doesn't come
naturally to me. It isn't obvious to me where the flywheel is either.
I guess that's where the CAS is. Is it accessed from underneath with
the car on blocks? If the timing chain (belt?) had snapped it would
sound like a bucket of bolts when it cranked, right?
The other thing is how do I tell if I have a 24x or whatever CAS?
VIN from the registration starts with: 1G2WH54TXNF,...etc.
Weird thing is why would it drive home fine and then contract sudden
sensor death syndrome while parked overnight? It hasn't been running
progressively worse or anything in recent weeks. These things usually
happen on deserted logging roads at night or on the way to airports,
weddings or job interviews, not while you're sleeping.
Thank you for your time, wm.
