Only way? Starter cranking? whazzat? LOL
My electric fuel pump is activated by a toggle switch on the dash. It is
wired to a hot terminal on the ignition. Depending on how you wire it, you
may have to turn the key on (not start, just on), or maybe not. I don't --
but it is on a race car for me, so the first thing I turn on is the master
switch. If the car did not have a master switch I would wire it to an
ignition terminal where the key had to be on first. Juice comes direct from
the battery.
Then I just flick the switch and the fuel pumps start pumping.
Then I open my Accusump and get oil pressure.
Ahhhhh, oil pressure AND fuel pressure -- then I hit the key and start the
car.
And it is KISS.
If the engine is cold, sometimes it still takes a bit of cranking before it
will fire, but I have a new (as of a year ago) toy for that too -- one of
Ted Schumacher's nifty gear reduction starters. Unlike Lord Lucas's unit
that kicks the bendix off the flywheel gearteeth when it catches (and then
doesn't start so you have to do it again, and again), the gear reduction
starter bendix goes the other direction and it will crank nonstop until the
engine fires. So when it "almost" catches, you don't let go but keep
cranking until it does.
This unit is so cool -- last August when I had an ignition problem, I was
able to drive the car back to my paddock on the starter motor.
