[V8] Hello (again), and maybe some advice?

[Dave Saad]

Hi Bryan,

Your symptoms don't really sound like the sensors to me, but they are  
almost certainly bad anyway.  It seems they have a design flaw that  
ensures an intermittent death. If yours are not bad yet they soon will  
be.  I think the average age is in the 150K to 200K mile range for  
failure.

Anyway, to debug your problem, I would first read the codes from the  
ECU.  A bad sensor should show up there.  Or, if you have a volt meter  
and a friend, put the meter across the supply wires to one of the  
ignition coils and have the friend crank the motor. If you get 12  
volts during cranking then the sensors are probably working. If not,  
it could be a lot of things, but the most likely might be the fuel  
pump relay.

Dave
