This points to a question I've had for some time: Why don't fuel
systems have some kind of pressure switch which feeds into the computer?
Especially port injection?
That way, if certain parameters are met, like crank sensor pulsing,
but the fuel press is out of range, it would set a code which points
directly to the fuel system (more specifically, low pressure in the
system) right off the bat.
It would be put in the loop serving only as a diagnostic device, but I
don't see how it could be very expensive--just a simple pressure switch
and the ECM does the rest.
It could, for example, wait a second or two after beginning to crank
before it processed the pressure signal, to let it build up pressure,
I guess I'm thinking only of closed loop, though.
Or would it be too much of a hazard in the unlikely event the switch
failed (began leaking)? Is that the obvious thing I'm missing here?
It also seems like they could have a similar parameter during which
time the voltage at the pump is monitored.
I'm just throwing this out for all you guys out there, your 2ç.
Maybe I'm way off here, but I'd think that if such a setup was extant
in the OP's car, I wonder if they would even need to be posting here.
I mean, it sets codes for everything else, for Gawd's sake. :0)
