No power to fuel pump

Have replaced tipm fuel pump crank and cam sensor. Have power to the fuse but no power out of the tipm. Jump a wire over and it runs fine.

Sounds like the relay failed inside the TIPM for fuel pump you said you replaced the tipm tho? The relay is not to hard to change its $5 and you just re solder it. Also make sure the plugs under the tipm are in all the way maybe remove them and re click in.

Yes it's a new tipm. Checked plugs and cleaned with detoxit. Have also replaced pump , cam and crank sensors. Fuse has power but still no power out of the tipm

Was the tipm programmed? and where did you get the replacement I would possibly send it back make sure all relays and fuses are in place in the tipm. Its easy to not install one when swapping from old tipm to new. Also does the truck have any codes have someone scan it with a good scan tool.

did you get the TIPM from dealer or salvage ?
they are vin specific
i changed a TIPM in my Grand Caravan went salvage didn't work wouldn't start! spoke to a buddy who is also a mechanic like my self and found out they are VIN specific went to dealer gave parts my vin ordered it put it in and presto it started also make sure that all wires in the connection blocks are all in place and tight (push wire block in and push wires in each space
