[s-cars] was: dead pig, now: fuel pump?

[David Kase]

I actually think I blew my ECU fuse when attempting to get the codes.  
But, when I found the fuse blown and removed it, I found it corroded.

I think the corrosion may have been my initial failure.  So...if you get 
that far before finding anything, you may want to pull the fuse to check 
the connection anyway.

Of course, if you have no fuel pressure, a blown or corroded ECU fuse 
can be the problem.  I was troubleshooting my fuel pump and found that 
it was not getting power.  I should have checked the fuse first as it is 
easier to get to.  BTDT.

Also, checking for residual fuel pressure in the line takes about 10 seconds... and can very quickly identify your cause.  Crack that banjo bolt on the front of the fuel rail.  Fuel will either spray out under pressure, or it will not.
