Ford 7.3L Power Stroke (1999-2003) :: Air Intake Relay Bad?
Mar 17, 2017
While doing a visual inspection I noticed that the AIH hot wire (captured nut wire) had broken off and was laying loose. I removed the wire from the relay and made a new 8 gauge wire, I connected it to the relay and was about to add it to the AIH when I got a healthy spark ( it touched the ground wire ) and yes the truck was not running and the key was out at the time.
This sounds to me like the relay has gone south, am I right??? I have a new OEM relay to install but I have a question. In what order are the wires and ceramic fitting go on the AIH post???

What does it mean when you find oil in in the cold air intake, is this normal?

The relay for the fuel pump keeps going bad. Is this a sign my fuel pump is going ? I just replaced my 2nd relay ( lasted about 1 week ) 1st lasted 16 years. Or is there another issue to look at ?

I have searched everywhere for the location of the blinker relay on my 02 F-250 7.3 and getting mixed results and still not found.

I purchased one of the No Start relay for my 2000 Ford F-250 Turbo diesel and need assistance finding the relay to replace.
Originally I thought it was for the fuel pump then then discovered it replaces the ignition relay.
According to the company it's located on the passenger side under the hood. Can't find any fuses there.
I looked in the user manual and found nothing about an ignition relay. Just "PCM Relay Coil, Ignition Coil (Gasoline only), Fuel Heater (Diesel only), Wastegate Solenoid (Diesel only), Injector Driver Module Relay Coil"
The relay I purchased is from: "No Start" Relay, "No-Start" Intelligent Relay System, Vehicle Theft Deterrent

Had a weird issue come up this weekend. I went to drive my truck for the first time in a couple of weeks and when I got in I noticed a constant clicking from under the dash (whether the truck was on, off or if the indicators / hazard lights were on or off). I investigated and found it was my flasher relay. I have replaced this relay recently (within the past year) to an EP27L to accommodate the LED lighting I installed throughout the truck (hyper flash on the old relay doesn't even describe it properly, it was a constant buzz!) and it has been working perfectly until this point.
I thought it may just be something going on with the relay so I pulled it and replaced with the old EP27 unit I still had. It does the same thing, albeit at a slower rate (every 4-5 seconds). The lights do not blink when it is doing this, but still operate normally when I move my stalk up or down or when I press the hazard / flasher button on top of the steering column.
I am wondering if there is a short somewhere in my multifunction switch that is causing this issue? If so, why would it come up when truck has been sat? I didn't have the time, not the inclination to roll around inside my truck (hotter than hades here in Florida right now) to troubleshoot any further. I pulled the relay altogether until I get some time and cooler weather to look into it further. Otherwise the truck seems to operate as normal, even all the lighting seems to have no ill effects from this?

Noticed a while back that the plug for what I assume is the air intake temp sensor is looped. I assume because I can't find the sensor anywhere. how critical is the sensor? The new S&B has a hole for it so it's either gonna need a new sensor or a plug. The local autozone has one for 16.99.

Dumb question but how do I remove the air filter intake from the turbo Its a little oily there from a fuel or oil leak but I dont see a clamp holding it on the turbo?
Also what is the e clip? Is it the little thing holding the wastegate rod on the exhaust turbine? Can I just pull the rod up off the clip?

Any pic or wiring diagram of the starter relay that is mounted to the fender. I'm trying to start the truck finally but it's just cranking and I think I might have mixed up the wiring. Is there supposed to be a constant hot at the glow plug relay when the ignition is off?

Upon trying to start my 2003 f250, it keeps blowing the 15A "Transmission Range Sensor then to Starter Relay Coil" fuse. Initially the truck would still start if i did not use the aftermarket Viper keyless start. however, now it doesn't start at all and keeps blowing fuses. I contacted the guy that installed the alarm thinking it might be something on his end. He walked me through reconnecting the factory starter wires which would isolate the issue if it was something on his end. it's still blowing fuses. battery terminals are good and clean.

Alright so I have a 99 7.3l. One day I went to start my truck and when I turn the key to the on position all is normal and then when I turn it all the way to crank it nothing happens. I hear a relay click ann thed that's it. Me and a buddy of mine spent quite some time on going through the entire truck. The starter was replaced, the neutral safety switch was replaced and the ignition switch was replaced yet the problem is still there. We then discovered that fuse #20 under the dash keeps blowing with every turn of the key. The manual states that this fuse is a starter motor relay coil PCM ( gasoline only). So if it's gas only why is it even in there. Let me just say that I can jump the fender mounted relay and the truck starts.

I own a 2003 E450 (transit bus conversion) with a 7.3L w/ California emissions. I recently noticed I have a considerable amount of oil in my air intake going back all the way to my turbo starting where the crankcase breather tube attached to the air tube. The breather seems to have some sort of filter housing that is attached to the top of the valve cover. I removed it and it appears to be fairly heavy as in if it's a filter, perhaps it's full. If I'm getting oil into my air intake from where the breather tube comes off that housing and joins in my air tube back to the turbo, could that filter or housing have gone bad? It appears to be a dealer stock item only for 225. I've saw on the web people posting "reroute kits" for the 6.0L but nothing for the 7.3. Does this part simply need replaced or could I be facing a separate issue as to why I'm getting oil in my air tube?

2001 F-350, 7.3L,
Has done this off & on for a few years and am tired of it! Noise is kind of a buzzing that seems to come from the flasher/turn signal relay. It stops buzzing when you turn on a turn signal, activate the flashers, or lift up on the shifter arm(?). Had to drive home yesterday with the flashers on! So I see from researching that it may actually be the multi-funtion switch on the steering column. So I removed that, cleaned up all the contacts, and put it back on and the buzzing did not go away.

Put in my new S&B intake today and when I stomp on the gas I am getting a loud shuddering noise from the intake when I change gears. Also sounds like a squealing sound sometimes. Doesn't sound like other trucks that I have heard. What that could be?

After installing new glow plugs, glow plug relay, and valve cover gaskets my 2000 7.3 is throwing the 1395 code. Glow plug monitor Bank 1. Any input as to cause? Checked all connections to relay. All tight. Read something about fusible link. Where that is located? One side of relay reads 0 volts.

I have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?

I have a 03 6L Ford F350 and for the most part trouble free. Any way lately I have been getting a clicking noise that sounds like a relay clicking under my dash when my truck is running even when its just idling...
I don't always get it but it has become more common that last few weeks. So I stuck my head under the dash and it sounds like it coming from that little black box's that is attached at the base of the gas pedal ? Could be coming from fuse box cause that what i was going to go after but doesn't sound like it, SO what is the little back box for on base of gas pedal?

My 2003 f250 6.0l just up and quit. It make a popping noise out of the intake when cranking. I am getting 1150 psi at the icp and ipr is at 62% which seems high to me. The FICM voltage seem fine unless the batteries are drained and I am getting FICM sync. I replaced the HPOP, ICP sensor and IPR about a year ago. I recently replaced the air conditioning compressor and power steering pump. I am at a bit of a loss. I did pull the IPR and everything looked fine.
