Been kicking this stuff around in my brain (no pun intended) all weekend.
Is it possible that there is an ignition switch problem?
Is this correct?:
Turn key.....Brain reacts by running pump for 2 seconds.
If engine starts, brain then "understands" that engine is running and thus
runs the fuel pump continuously.
I assume that there is not an ignition switch wire that goes to the pump
relay under the dash. Otherwise it would run all the time, even in an
accident, which it not what is desired. If that's correct, then could
there be a problem between the ignition switch and the brain? Seems that
either there is a problem in the brain (likely) or the brain is not
understanding that the key has been turned.
However, it also fails to run the pump when the engine is finally up and
running. SO, maybe my thought process is wrong....
