Ignition stalling solved, gas related stalling now :(

[Chris Hall]

I've been told putting a resistor inline fools the ECU in to thinking 
that the engine's cold all the time, so it dumps more gas in to the 
engine for "uber power" and that really all it's doing is wasting my 
gas, so I'll probably yank it.

As far as my gas related stalling goes... I put a new ECU in ($5 on 
ebay) and I poped open both of the fuel pump relays I'd been switching 
between, and found smaller than hairline cracks on a couple of joints 
in each one.  I'm guessing the problem was in the relays (I probably 
helped these cracks form while swapping the relays when trying to find 
my 2 stalling problems haha).  I haven't had any problems since then.
