HOW TO: Check regulated fuel pressure, pump max output, & leakdown
16mm crow foot flare nut wrench, (Sears has them) on a 3/8" ratchet works great.

My 2000 blazer zr2 cranks, but won't start. Narrowed down to fuel. Threw money at it when fuel pressure tested below 55 psi cranking. New pump didn't change a thing. Wasted time and money. Started thinking pressure regulator. While I was searching more about how to further diagnose that, I hooked up battery charger to maintain. Damn thing fired right up. Unhooked battery charger and it reverted back. My question is how is this possible? My battery tests at 13 volts unhooked.
