I checked the sparks three ways. I have a spark tester which plugs inline
between the plug and wire. I also took out the plug and watched it arc
when cranked (wire connected). I also watched it arc from dist to wire.
The spark didn't seem all that powerful, but that's all relative. A weak
spark should still cause combustion.
I tested the fuel pressure at the fuel rail. When ignition was turned on
with banjo bolt unbolted, gas shot up out of the bolt as expected.
I'm at a loss on what's going on since I'm getting spark and fuel. I haven't
checked if I'm getting air (not sure what the best way to do that is). With
all three present (air, spark, and fuel), I should be getting combustion.
perhaps my timing is off because I have a supra that won't start if the timing
is way out of range.
