99 Ford Windstar 3.8L, 139,000 miles.
Vehicle has sat for unknown amount of time.
Would not start.
Replaced oil, oil filter, air filter, fuel filter, cleaned TB and checked all fuses.
Noticed fuel pump would not make “rumble” when key turned to on position.
Removed tank, noticed no pressure in fuel lines. Tested old pump, failed test. Purchased, tested and installed new pump. Noticed still no “rumble” when key turned. Checked fuel relay, made “click” noise and passed continuity test when charged. Inertia switch not tripped. Still will not start. What am I missing?
Ground.
The fuel pump requires a good battery positive and a good battery negative. Make sure you have both.
