If you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

1990 ford festiva no power to fuel pump. replaced relays , fuel pump, checked safety shutoff. nothing .. ran hot wire to fuel pump and pump worked but car still not trying to start. got spark. now what


The pump should have a fuse in the fuse block. You need to check for power in the fuse block and you need to check power to the pump relay.

Sometimes there is a fusible link to the Relay. If you check the connector terminals for power where the Relay plugs in, you can determine if the fusible link has blown. You could have already replaced the bad parts and now need to restore power to the Relay.

EEC relay fuse keeps blowing id put a new fuse in the truck it would run for about 10 seconds then blow the fuse again.


There are 3 relays mounted below the fuse box .
The green I believe is fuel pump relay and the brown is EEC. The third relay is for the A/C WOT.
It is possible the wiring is shorted, check there, it is also possible you have a bad fuel pump.
Please let me know what you find.

2008 Ford F450 fuel pump relay fuse keeps blowing.


the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.

Ford explorer eec relay


Try a new relay first. This may not be good news if that does not work. If you can find the EEC (computer) and unplug it, then replace the fuse-if it blows you have another cheaper part on the circuit thats bad.
If the fuse does not blow, then the EEC must be shorted.
If you have to replace the EEC you may find a kindly dealer with a cash-for-clunker sitting there to violate. Salvage yards have them, Ebay sells them. I have seen them at swap meets for $20. They are a high price part even rebuilt at Dealers or autoparts stores.

Replace the fuel pump relay, it is not uncommon for them to get stuck in the "on" position. The relay is located on the front right inner fender panel.

Keep blowing fuse for fuel pump


If it takes more than a couple of hours to blow the fuse its most likely the fuel pump. If it blows instantly you could have a grounded out feed wire (+) wire or a bad relay. Look in the haynes manual to get the location of the relay.
