Ford Wiring/Electrical :: 1997 - Fuel Injectors Not Working?
Jul 3, 2017
I swapped a 4.9l into a 1997 F-350 that had a 5.8L originally, my issue is the fuel injectors are not working. I did my homework and got the harness that was with the engine out of a 1995 F-150 and also got the correct PCM to go along with my E4OD tranny that is in the F-350. It has spark and 60 plus PSI fuel pressure in the rail and will run with starting fluid shot in the throttle body. Both vehicles came with OBD I so should be compatible there. I do not have 12v to the injectors and obviously the NOID light shows no pulse either. Could be a ground but not sure where to look or what else could cause this.

When doing my last spark plug change I noticed that the electrical plugs to the fuel injectors seemed really loose. The plastic tabs on the harness plugs don't even lock onto the injector plug. Its actually amazing that they don't vibrate loose or stay electrically connected. The plugs are not cracked or damaged that I can see. Is this a problem? I feel that I should replace the plugs with something that has more of a positive "grip" to the FI plug....

I have a 1997 F150. I installed a trailer towing kit round 7 pin. I followed the instruction and replaced three different fuses after installation. The passenger side turn signal will not work. I replaced the bulb. The brake light works and the bulb is on when the lights are on it just will not blink. When the turnsignal is on it clicks very quickly.

Just bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.

Need a wire diagram. I have a connector in the cab that has red,blue,lt green,white wires. It's causing my brake lights not to work. I need a wire diagram that shows were they go. I can't find these wires in my Haynes manual.

When we bought it the had cut off the wires going to both sides of the rear lighting assemblys and I was wondering what wire went to what i have the left turn signal working just can't seem to get the brake/back up light to work on that side and i can't figure out how to get the right side going either.

Turn signals quit working on my 2006 E-150. Swapped out the relay under the dash and it did nothing. Also noticed the brake lights aren't working. The headlights and taillight a are working. I pulled the fuses under dash for the lights and they tested ok. I did notice the flasher relay was making clicking sounds intermittently even when not touching anything.

97 F150 4x4 XLT 5.4L... I had two cylinders misfiring, removed COP, injectors and plugs. Reinstalled all parts and reconnected all sensors. Now I am not getting fuel to the injectors. Double checked for disconnected wires and hoses, checked all fuses and relays, also the inertia switch. Fuel pump does not hum when key turned on. Tried hitting bottom of gas tank. My question is, before I pull the tank again, is there something under the hood I may be missing. It does get quite crowded at the rear of the motor.

Truck is in signature. All of a sudden my oem fogs don't work. I took a volt meter to the connection where the bulb plugs in and no juice. Checked the fuse and its good.I get 12 volts or so at fuse for fogs.. The fog light illuminator lights at the switch when I pull the switch. Is there a relay somewhere under the hood. All the relays in the fuse box checked out good and none of them in my truck guide were labeled for the fogs anyways. Looked for 3 hours and cant find a thing. If all else fails how do I cut the wires at the fog lights and run wire to cab with toggle switch? I know I need a relay right? I am not familiar with hooking up relays..

I have a main tank and an Aux tank with a gauge selector switch. I believe I may have a bad fuse as the indicator has stopped working. Where it is on the fuse block??

I have a 1994 Ford Ranger king cab 4x4 with a three inch lift kit on it . My problem is the fuse is blowing that goes to the fuel pump . It started out blowing the fuse now and then when it was raining . Well I thought it mite be the fuel pump going bad but after I put the new pump in the truck it lasted about a week and started blowing fuses again . I put another fuse in and it go a few days and blow it . Last week on a 100 mile tripe I got almost there and it burned a fuse on the highway . I tried to put another fuse in and it would blow it as soon as I tried to start the truck . Burned five fuses right then . So I had it towed to mothers house and put another fuse in and it cranked up . I looked at the wiring that was not wrapped in that plastic cover stuff and have not found anything yet ...

My brake lights don't work. Turn signals, tail lights, hazard flashers work, but if I hit the brake, nothing happens. What could possibly be the problem? Could there be a wiring issue?

I did lower the steering column, onto the seat. Also lowed the dash and the wiring. Does it sound like the Multifunction switch could be bad? I can put it in drive, so I don't think it's the brake light pedal switch, that's bad.

After changing my radiator support, my fuel and temperature gauges don't work. I looked to see if everything was plugged in and I don't see anything unplugged. I do know the older trucks used the V-R regulators, but I don't know about this model.

I have an 01' f150 that everything is going out on. I've replaced the GEM module thinking that's what it was to no avail. First thing to go was all four windows which have currently been stuck halfway down for 2 weeks. It's stalling out during idle like it isn't getting enough fuel to it. Brake and engine light on dash are staying on. Radio, interior lights won't come on. Will not come out of park once in. I have to do the old forward, back, middle key trick to get it out of park into neutral so I can start it and go. I've also checked all fuses and relays under dash and under Hood.

I got my first truck today and it's a 1988 Ford F-150 and it runs great! The only issue is that the speedometer doesn't work and I won't be able to register it until it does. I was wondering what I can try out to maybe fix the issue and if not, how I would replace it. Every other gauge works, it's just the speedometer that isn't. The needle doesn't move at all it just sits at a 0 all the time.

I have been trying everything to get my speedo working on my Ford. It didn't work for 3 months after I got it then I decided to put some gear oil on the cable. This made it work for about 200 miles then it would only work with the clutch in and then not at all. I've replaced the speed sensor(not one on rear end the thing the cable goes into), and the gear that goes on the end of it. If I hook a drill up to the cable the tach moves. Could the cable be stretched or just needs some speedo cable lube?

My radio, all gauges and windows aren't working. Fuse 17 did not seem blown but I changed it anyway and still no luck.

I have a fuel pump I want to install I want to hook this thing up on a switch inside the cabin to be used as kind of a security device, but I am hoping I can wire it into the ignition as well.... I want the pump to activate when the ignition is turned on but only if the (hidden from view) switch is in the "on" position. Not sure if all this is possible.
I have heard I ought to utilize a relay to avoid voltage loss at the pump. I have never hooked up a relay to anything before although I have heard of them being used. This system is being installed on a 1967 F250.
