i could use some help here
1999 4.0 gems with no power to the fuel pump. All fuses are good, i swapped out the inertia switch with one from a DII, no luck. i have spark , i have power at the imertla switch but no power at the pump connector.

You have two more connectors from the inertia to fuel pump - C277 and C407. C277 is behind the fuses under the steering wheel and not easy to find or get access to. C407 is easier, inside frame rail at drivers side rear wheel. That connector is usually the one that gives everyone trouble in the rust belt. I'd check that one for power to the pump.......C407. This is a Disco wiring loom.

Sorry i should have said p-38. the truck was runnjng shut it off restart 3 mimutes later just cranks? I will try and figure the schematic for a p-38 and see if its different. thx by the way
IHS thx schematic are not my thing, im in the middle of phisically tracing the wires from the i/s to connector. I have a question for you the I/S has a brown and orange with power and two white wires one vilolet the other a blue stripe. Which one should have power coming out?
White/Blue goes right to the fuel pump motor, that's power.
White/Purple goes to the BeCM, sense line.
Orange/Brown goes to the float from BeCM and probably splices through the inertia on it's way to the float.
