Ford Wiring/Electrical :: 1990 F250 Hard To Start - Glow Plug Controller Relay Wiring
Feb 23, 2014
I just bought a hard to start 1990 F250. Per the board, just replaced all 8 glow plugs with Motorcraft. Still wouldn't start (it turns over but will only start if you use either). I attempted to install a new BWD brand (Borg Warner I believe) glow plug connector relay today...I removed the old no problem, but am unsure what wires to plug where....the only connection that I'm sure about is the blue wire that works the WTS feature...it plugs in easily but I don't know if there are other connections that need to be made or not? All the wires run from the posts and into the bottom of the unit.

My truck is a 1990 F-150 with the 351. I was replacing the spark plugs last night, got it all wrapped up and everything squared away, and after firing the truck up I noticed a ticking noise. It was not there before I replaced the old plugs, and it is not at all loud. I can hardly hear it with the hood closed. It appears to be coming from the driver's side of the engine. It does not misfire when its idling, and it revs smoothly. However, while driving it is noticeably choppy and feels sluggish.
Any thoughts on what it could be? I used dielectric grease on the boots, but I did not replace the plug wires themselves, or the distributor cap. I am probably going to replace the plug wires today though, because the plugs I took out were not in good condition and its been a bit too long since I replaced them last. Its also worth noting this engine is less than years old. This is a frustrating problem because I've replaced the spark plugs on her before, so I'm not quite sure what I did wrong this time.

I have a 07 f250 6.0l and it has 112k on it, I've owned it for over 4yrs, since 45k, and no issues, but this morning I went out to start my truck didn't start, tried again and started, but the glow plug controller made a funny buzzing noise, (making that noise for a few weeks), so I went to ford and bought a new controller, so I hope that fixed that, but on my way to work I was at a traffic light and noticed that my ficmv were between 46-48.5, icp 23-24%, vgt around 68%, truck was at temp, should I start to worry about the ficm??, I have to replace my ground on driver side battery, noticed that it is corroding, gonna do that, I have 2 yellow top optima batteries about 3 yrs old....

I have a 97 F250 HD. Wiring the rear tail lights. 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.

I have a Derale 16749 electric fan controller set up had a fan die, went back to a old set up using a fan shroud I made and sable fans being the controller isn't set up to handle the load from these fans I want to just add relays in. Way the derale is set up to the fan is 12v. constant but the ground is also a 12v. until the switch reaches temp. then becomes a ground. I am not concerned with wiring the low side up on these fans just high side.

My truck had power to the Brake Controller until a recent road trip and now there is no power to the controller. All fuses are good. Which circuit the power comes from?

I'm new to owning a diesel. I have a. 2004 f250 6.0. I gotta smog the truck this weekend but the check engine light is on. Fault is P0674. I've notice during the day it starts up fine but at nights, lately it's been low 40 outside it won't start. Where to start at.

1999 - F250 7.3L Crew/Longbed manual locks/windows ...
2x New Batteries a few days ago, same symptoms as old batteries ...
Sitting overnight loses .1 volt due to cooler temps in am measurement:
9pm 12.92v
7am 12.83v
11am 12.93v*
*won't start
The amp draw measured at 9pm and 11am is essentially zero (reading .06 or less, usually 0.00) on both cables exiting the passenger side battery. This is sitting for an hour plus with the hood courtesy bulb removed. (although it drops to near zero within a few minutes of the domes going off). Using a clamp around ammeter.
The alternator is charging (14+v reading while driving). When trickle charged overnight the truck starts fine. Plugging in the block heater makes no difference in starting (or not). 45 F overnight. When it doesn't start:
-double keying the glow plug light comes on
-tach needle bounces on crank
-voltage of 12.8 drops to 11.2 on glow plugs, then 10, then 7 while cranking
-sounds like it's almost going to catch, then bogs hard and the voltage really drops
Again, it starts fine when charged and starts after short trips (by virtue of my wife having made it home). Haven't tried to jump start as I don't have anything handy that is boss enough to jump one of these. Typical use during failure:
Charging with charger
Start
30 min to store
3 stores, start 3 times
30 min to home
Sit overnight
Won't start
This morning I checked that the battery terminals and battery clamps all had the exact same voltage. There are occasionally amps between the batteries (.37 to .08) measured on each end of the cable going over the radiator.
So, if there is no drain and the block heater doesn't work, but it starts fine if it hasn't been driven/sitting, what is next to check?

While the owner of 2 Ford Trucks, I also have a 2004 Ford Taurus with 28K on it. For a while now the vehicle is hard starting, cranks but acts like it is not getting fuel, however, I can hear the pump come on. Other times it starts right up, but a clicking sound can be heard coming from the firewall area. At times the gauges will not immediately respond when the Vehicle is started and then all at once they will begin to work. Now, my check engine light is on, but my hand held obd will not read it. All the terminal pins look great, obd tester works on my other two vehicles, cigar lighter working, the fuses i checked are good. Vehicle runs great. Can this all be related to a bad module?

95 ford f250 with 5.8l. I have currently replaced the battery, alternator, distributor, cap, rotor, icm, coil, plugs, wires, act sensor, ect sensor, fuel pump, fuel press regulator. I got it to start today by messing with timing at distributor it ran to operating temp and died. Would crank but not start.. So I replaced the act tensor today.. Now it still won't start... koeo test gives code 327... I am stumped and about to tow it away...

My 92 F250 5.8 won't start but fuel pump runs all the time the key is on. Some times it runs. But has no power and check engine light is on.. But I cant get it to flash codes, only steady light on.. It did this before then ran good. Now back to no start.. I checked grounds and relays ..

My center brake light went out a month ago. Thought it was the bulb so replaced that, still didn't work. Checked the fuse and its not broken so my guess was electrical?
Hasn't come on once that I know of but I was randomly walking behind my truck and the light was on. Truck was off lights were off and key wasn't in the ignition.
Went and turned my truck on and turned the lights on and the cbl stayed on. When I switched my lights off it went out and stayed out.
Now I'm definitely thinking wiring but not sure where to start fixing?
Oh and it's a 1990 F150 XLT

Long story short, my truck's front turn signals and rear turn signals/tail lights won't work. I am thinking that the relay is burnt. Whenever I look in the manual I can't seem to find the location for this relay. Is is built into the flasher?
Also, I am just assuming because the rear turn signals and tail lights are the same bulb that fixing this should clear up both problems. Am I right in thinking that?
I have already checked all of the fuses. Also, the Hazards don't work either.

I am having issues with my auxiliary relay on my truck. It will work intermittently. It started with me just needing to give the relay a light tap for it to work, and is now progressed to needing me to push really hard on the relay for it to turn on, but then as soon as I let go it shuts off again. I have replaced the relay with a new one and it's doing the same thing, and have even tried some di-electric silicone on the terminals with no success.
I was thinking of pulling out the entire fuse/relay panel and see if the contacts have pushed out, but then I read a thread regarding the panels and issues involving the removal the terminals and breaking the panel. 2004 F350 CCSB 6.0L...

I have a 2000 F350 7.3. I started out with my batteries dying after a few days of sitting. I found the interior lights were coming on dimly, and the relay buzzing. great, got it. I pulled the fuse and ordered the dimmer/light switch. I came back next week and the batteries are dead again. Charged them, drove the truck, and then the radio starts coming on without the key on. Pulled the radio.
Next day the truck starts fine, but now the seatbelt noid is going off all the time and the tranny overdrive is blinking "off" but still shifts fine, and goes into overdrive. The speedometer also works erratically... I read a post about the marker lights leaking, I looked and that's a definite possibility. My question is are all these related back to the GEM or BCM? or more problems?

I'm planning the install of a 1996 351w into my '77 F-100. I'm using the '96 accessory serpentine drive (FS-10 A/C compressor, '96 alternator, etc.). It needs to mate up to the '77 wiring. I'm going to use stock '96 underhood A/C components (accumulator, hoses, condenser).
As best as I can tell, the '96 system uses the ECU to manage the A/C system, but I've converted the '96 motor to a carb.
Looking at both the '77 and '96 systems I think the easiest underhood wiring solution would be to use the '77 compressor ON wire as a relay trigger, and use the '96 High Pressure Cut Off (HCPO) on the compressor manifold, and compressor cycling switch attached to the accumulator to interrupt the relay output to the compressor.
I can get the switches and pigtails, and I can look up their pressure trigger points, but I don't know the voltage the '96 switches operate at (12v or some reduced voltage?) or how to simulate their trigger conditions to see how they work. I guess that at ambient pressure the HPCO should be normally on and the cycling switch should be normally off. So I could just wire them into the relay ground or trigger connection. But of course they aren't simple two wire switches. (Edit: Looking at it online, the cycling switch appears to be two wire, the HCPO is 4 wire).
How to wire them, should I use them to interrupt the relay ground or trigger connection?

In an attempt to bleed my drivers side caliper today I noticed clicking coming from the #2 relay switch under the dash. The clicking stopped once I pulled out the relay. I continued to bleed my caliper which I've been having issues doing so. It was kinda odd how I was able to bleed the caliper after pulling the relay. Is it possible that the [email protected] system could be causing issues with the pcm? 2000 f 150 4.2 v6 232,000 miles .....

My vehicle would not turn over and we could tell it was fuel related. The fiel pump relay has burnt through the motherboard of the fusebox. It is my understanding that this cannot be fixedand another fusebox must be installed. I have been to many junkyards in my are looking for it to avoid the dealer prices..all of the expeditions that we have found locally have already had the fusebox pulled. Any other vehicles that this might be interchangable with? My friend has an 01 expedition..would this work?
