Hello,

I bought a used 99 v10 F350 4x4 from a good friend of mine last month. It has 205k miles, he has always regularly maintained the truck and it was running like a dream for a good 1000 miles after I bought it before it started randomly dying.

It randomly will die at startup, at low RPM's, at stop lights, when turning etc.

When it dies there's a very noticable ticking sound that occurrs from 5-30seconds and while the sound is ticking away you can turn the key and the motor will turn but it wont fire up.

I've changed the CPS and MAF sensor but still it's dying whenever she wants. I need this fixed as I drive down a windy cliffside road to work everyday and when it dies I lose all steering and power brakes so I've been avoiding driving so I don't go flying off a cliff.

I took a video and will uload it once I figure out how of the ticking noise and exactly where in the cab it is coming from.


EDIT: It may or may not be worth mentioning, when the "clicking" happens the Service Engine Soon light flashes in unison with the noise


Thanks for your help!!!

Let's see if this link works for the video.

 

When it won't start, have you tried pressing the gas pedal a little? It sounds like it may be the IAC.

 

Yes giving it gas doesn't help it just completely cuts out. But by some weird stroke of bad luck it just got worse. Driving to the gas station (2 miles away) it died twice and the second time the clicking went for a solid 3-4 minutes so I had to sit and wait... Please help!!! LOL

 

Link won't work for me. Where is the clicking coming from? Sounds like you need to start at the beginning...is there fuel pressure?

 

I'll probably need to upload it to Youtube as soon as I get home.

The clicking is coming from where I believe the ECU to be. I pulled off the fuse panel cover under the steering wheel and the noise is absolutely coming loud and clear from inside under where the AC controls are. The video shows what I am referring to. There seems to be fuel pressure most of the time because it runs absolutely fine with the exception of it dying.

 

Bump! Where are the v10 gurus at

 

This isn't a "V10" problem, it's a vehicle electronics problem and the truck just happens to have a V10.

Try a new PCM power relay.

 

The "clicking" sound isn't normally, and I don't think a bad relay will click like that (more than "don't think" more like "know it won't").

Are there circuit breakers in the fuse panels? I don't remember seeing any, but that's what it sounds like - something is shorting out, causing the circuit breaker to open (click), resets, and repeats.

Find the clicking noise - open the fuse panel, which I believe in your truck is under the steering wheel. Remove the cover, leave it off, and drive it.

I'm wondering if someone knew there was a problem, and replaced a fuse that kept blowing with a circuit breaker.

The CLICKING is NOT NORMAL - nothing I can think of would cause that, especially if it's repetitively in a pattern.

 

Here's the video with the dreaded clicking!


Hope this helps!

 

If your check engine light is on, you have to start there.

 

No the check engine light isn't on when the truck is on. However it does blink in unison with the clicking noise when the truck isn't starting

 

Wow, when you said "clicking" I thought it was much slower than that...

Do you have a remote starter?

 

What is the system voltage when this is happening? Actually, I have heard relays make a rapid clicking like that when the voltage is low. That sound is loud enough there should be some vibration you might be able to feel in a casing or cover.

 

Yeah, good point. Now that I've actually heard the "clicking" it definitely sounds like what would happen when the voltage is so low that when the relay energizes, the load causes the voltage to drop, de-energizing the relay, and back and forth it goes.
