Fuel pump issues

Your fuel pump relay went bad. But i'am not sure on that one where it is. Which side did the smoke come from? You may have to call ford and find out on the relay. They are usualy out under the hood but they put them where ever they want. NOS

Yes very possible. I though possibly that was where it was but you just don't know anymore the way there stuffing them full of electrics

Most times there mounted on the right side behind the kick panel or firewall. But I have seen them on the firewall driver side little black looking box with a red button. Do you have any panel in the back if so it could be in one of thoes (NOS) aburned up ignation switch can cause that problem also a stuck fuel pump relay can do the same thing.

I don't have a book right here with me. But I will be able to give you that info tomorrow but there is some grounds the by the battery that you sgoud check to make sure there in good shap and grounded good. Now I can tell you that thee EEC relay acts as a switch when you turn the key on it turns the EEC relay on and the fuel pump relay. The EEC relay also turns the computer on it turns the fuel pump relay off till the motor is cranked then it switches it back on. One thing you have to remember is that every time you turn the key on and off it sprays fuel in the motor the plugs may be fouled now. If you have not replaced the EEC relay do so they don't cost much and that will just elimanate it.I will look at a wireing digram tomorrow at work to see how it is run the fuel pump relay is a green one and the EEC relay is the Brown one. When you turn the switch on both relay click on after a few seconds the fuel real shuts off now one of the only reasons that don't happen is if the circut in the EEC relay don't shut off part of it stays on to keep the comp on and part shuts off to turn the fuel pump off till you start to crank. Look in on this tomorrow for more INFO.(NOS) 8) PS the switch that you bypassed won.T make one keep runing they will only shut one down if they go bad the truck won't start

Ok I got a little more info for you. From the switch a red /light green strip wire. This wire powers the coil it also powers up the EEC realy. Out of the EEC relay it changes to a red wire. This wire powers up the PCM which is the computer it powers up the fuel pump realy. I would deffentaly check over the grounds real carefuly on this truck the EEC or which is the same realy as the PCM which is the Power Train Control module. Off the fuel pump relay there is a Dark green wire with a yellow strip that comes out of the computer. There is a yellow wire which should be hot all the time at the fuel pump relay. The light blue with orange strip also goes to the computer and the DATA link connector. You ver possibe have a smoked computer. (STOP) check all these circuits first and find the short cause something caused that smoke. Don't replace the computer till you find it you may just smoke another computer look for bare wires touching ground somewhere. Or even loose grounds can cause enough load on something to smoke wires man hope this tells ya a little more if not get you a good test light and a chilton book they have all the wire Diagrams in them don't get me wrong I don't mind helping ya but sometimes info gets confuseing trying to explain it this way.(NOS) 8)

Check the inner finder. If water splashes up inside there that is how it got wet in the wheel well there should be a flat peice of rubbr covering the the bottom part of the finder if not water can get up in there that way. And np I like answering just make sure that you send a post to BoB and KEN and tell them. That is how they keep this site open.(NOS)

Sheanjosh you should ask a 'new' question rather than enter it into this old post.
