2000 chevy astro! Fuel problems. Checked coil good. Took out fuel pump, had it tested good! Grounding problem maybe? Is there an auxilary ground somewhere? Solid black is the ground? Everything else shows current? I'm lost

Find the inline connector going to the gas tank unplug it on the harness side check terminal c it should be a constant ground. Now check terminal b the grey wire it should have power while cranking the engine. Let me know what you find.

Alright there isnt supposed to be power on the ground wire. Was there 2 ohm or less to ground on the terminal c ground wire?If not you will have to start by fixing that.

Terminal C how do I figure out which one that is? I have a purple wire w/white stripe, a black wire w/white stripe, a white wire w/black stripe and a solid black I'm assuming the solid black is ground?
