1998 Bonneville SE 3800 V6. Question = Engine
will not crank. New battery, power is available
when ignition is on. I've heard that the crank
sensor might be the cause?

There is absolutely nothing when the ignition is
held in the start/crank position. No sound, i.e.
Clicking, just silence. Any suggestions? My
stepson complained that when the engine was
idling and the car was warm, the engine would die
prior to this happening. We took it to Autozone
and no codes were found? Thanks for your advice!

You may have a poor connection at one of the
battery terminals, a bad starter, or a security / theft
problem. Test for power at the purple wire at the
starter while trying to crank, it should have power.
If it does, you have a bad starter. If not, then a
possible security / theft problem. Look at the dash
after trying to crank, and release the key to the ON
position. If the theft / security light is on or
flashing, then you have a fault in that system and
it would need to be diagnosed.

Question = the fist code was bank 1 running to lean changed
plugs wires now this code comes up mass circuit voltage low
what could that be.

You could have a vacuum leak. Suggest checking for that first.
Next, check all fuses, then check the wires at the MAF sensor
connector. Sometimes they break inside the colored insulation.
Pull slightly on each wire at the connector. If a wire is broken,
then the insulation will stretch. This will give the P0102, which
may also have given the lean code.
