So I drove my car to work and have not been able to drive it home due to a no start condition.

My alternator gauge had been fluctuating rapidly at idle for about 2 to 3 weeks (between about 13.5 and 15 Volts) so I had taken a minute at work just to check to make sure the battery cables were tight, and the wires at the alternator were tight and that there was sufficient water in the battery.

All wires good and tight then 2 hrs. later when I went to drive home it cranked but wouldn't start. Luckily there is an auto shop at my workplace so we began troubleshooting.

It seemed like a no spark condition but we sprayed some starting fluid into the intake hose and the car turned over and ran until the fluid burned off = no fuel, alas the fuel pump was not making the normal sound, no sound and no click at the fuel pump relay, fuel pump relay fuses were good and I cleaned the fuse terminals and still no power to the relay.

I started swapping parts... here's the list of parts swapped out so far

ignition module (power stage?) tried two different modules
ignition coil
fuel pump relay
fuse 4 and 6
checked ground connection to in tank pump - it looks and feels clean and tight

Got lucky (or divine intervention depending on your belief system) and found a 951 ECU in the junkyard on my first visit!!!

after swapping in 951 ECU still cranks but no start.

so - here I am at the Brickboard... any thoughts would be greatly appreciated

would the engine crank if the RPM Sensor (Crank Position Sensor?) has failed?

Thanks in advance,

Jack
