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

[Bryan Kamerer]

Hello guys,

Thanks guys for the advice.

At 157k on the odo on mine, I'll change the sensor anyway I guess. Hopefully
that will get it back on the road.  150k is a reasonable life I agree,
Steve.  I guess they should have just specified the part be replaced at 100k
intervals like the timing belt so people didn't get "shocked" by the
failure.  So I have a 5-speed, I can access this item from the top beneath
the driver's side coil/distributor area?  Ok, that's not so bad. Someone
said they pulled the coil and distributor.

Question: what is the difference between the rpm sensor and the "speed"
sensor?  Does it commonly fail, too.  Should I replace both?

 I don't have the 2x2 adapter or reader for this vehicle, though I'll order
some off ebay for the future pronto.  In the interim, isn't there a way to
"blink" out the codes I've heard?

About the fp relay idea: Is there a way the fp relay could kill the spark?
If I pull it and jump it, I get the pump running, but otherwise the pump
doesn't even come on with ignition on or cranking.  This was the first
anomaly I noticed; something was preventing the fp relay from kicking in or
it was killing the spark. But I just don't understand how the sensors and
ECU interact.

Tomorrow I'll get another voltmeter and check the coil inputs; mine died
recently and I hadn't replaced it yet. I checked the power with a continuity
tester (light), not with a proper volt meter.

Nice to have the help - and I sure recognize Steve's name and I think
Dave's, too, from way back...

Bryan
