Alarm system woos

"Finger now raised to saluter Ford as Number 1.

Yep, its dead again.

My son went out last night and while driving the truck just quit; just like before.

Ideas....."

Since it's still under warranty don't aggravate yourself,
bring it back to Ford and let them figure it out. I know it's inconvenient but it's probably the best course to take. My gut feeling is that it's a fuel problem of some sort, however, I am really not qualified to say this with any degree of certainty. Did you check the fuel pressure when the condition existed?
As I said "simple is better". Best of luck and keep us posted.

Oh boy, the dealer said they fixed my truck and to come get it. Said it was in the ignition switch.

Picked it up last night, ran like a dream. Frove home, a couple miles, and then went to the grocery store. On the way home, it simpled stoped running while driving down the road at about 30 MPH. Would not restart.

I called my mechanic and he came over with his code scanner and got the message "NO DATA AVAILABLE" that we had gotton before.

About an hour later we went back to get it towed and it started perfectly. Explain that one.

Help, what the heck is wrong with it?

Got it back again. The dealer said they replaced some relays and it worked fine in all their tests including a road test.

Doubiously I picke it up and have neen driving ity in the neighborhood for about an hour. So far all is well.

I am scared to go far.......

 

[aldive]

So far so good....

I left the truck running for 8 hours. During this time there were drives through the neighborhood for about 7 miles each.

Hope its fixed.....

 

[aldive]

The black magic appears to have worked.

Put 100 miles on it testing today; all was well.

Fingers still crosses except for the one standing erect for the terrorists....

Glad to hear all is well. It's really a lousy feeling driving around, being uncertain about the vehicles reliability.
Just curious, did they tell you what relays were replaced,
since it's more than one I would think they replaced more than needed just to make certain they have fixed it for sure this time. Thank God for the warranty, would have been a shame for you to fork over extra cash for their inability to repair these complex vehicles we drive today. I sincerely hope you have peace of mind now in regards to your vehicle.

TROUBLE IN PARADISE....

Iy happened again, The damn truck is dead, Ran perfectly yesterday all day long. Went to crank it this morning and it was dead. Everything works fine except for actually running.

Ideas???????????

Sorta sounds like the same problem people who had bad performance chips have experianced. Which to me points to the computer.
I think your truck is "brain dead".
A whole lotta help arn't I?

Bill, its me thats going braindead over this...

I jave never added a "chip" to the truck, thats one thing it can't be. Wish it were that simple though.

Ideas, anyone? Heko.......

Sorry to hear it won't start again. Perhaps you should leave it alone and not try starting it again. Then tomorrow call the dealer and have them come to your house with diagnostic equipment to attempt to find the source. As insignificant as it may seem, being parked at an incline perhaps may trigger the failure. By them towing it and disturbing the actual non start position may prevent them from troubleshooting correctly. It may be a longshot but it's worth a try, like going to the dentist when the pain is actually still there. Best of luck
and keep us informed.

Have them disconnect the theft system or disconnect it yourself.

Also, find the fuel cut off switch(in your manual) and make sure it is completely depressed. It is under the dash, passenger side, right side of the glove box, above the side kick panel. It may be a faulty cut off switch.

Good luck

I understand you don't have a chip. What i was trying to say is that I think it is computer PCM related. Bad contacts, bad PCM, something along those lines.
I suppose it's just as possible that a wharf rat ate through your ground wire while you were out so long on the boat giving that good looking women inspections, huh I mean instructions.

The diagnostic computer every time this happens gived the readout of "NO DATA AVAILABLE". Wgen shes broke she doesn't talk....

Help.....

As far as I know and have been told, the alarm system cannot be disabled. It apparantly is too interwover into other systems.

I shall look for the fuel cut off switch, Thanks.

Bill, the PCM has already been replaced. Same results as the original one.

Do I detect some jealousy about the boat and my bikini clad customers?

Other ideas?

 

[2001ExpSport]

I read in an earlier post that it would crank, but not start. If it was the theft system it wouldn't crank at all.

Just another thought.

Are you saying that the factory alarm system disables the starter from mechanically turning over the motor? I gave never heard of any alarm doing this. I thought the alarm disabled the starting electrically not mechanically....

Help

Some progress and good news, finally….

This morning we checked the voltage at every sensor. The sensors work in a 5 v reference. The sensors were all reading around 3.7 v. One of the O2 sensors was really off.

We disconnected the obviously bad O2 sensor and low and behold, the other sensors started reading 4.95 v. The data reader went from NO DATA AVAILABLE to normal readings. The truck started with one turn of the key.

A new O2 sensor is ordered and we will replace it this afternoon.

Lets hope this solves the problem…..

Yes, the security system disables the starter system. Even the two aftermarket ones that I had on earlier vehicles did the same thing. It will just go "click" when you turn the key. I hope it turns out to be the O2 sensor for your sake. It is extremely frustrating to keep taking it back to Ford and have them tell you it's all better now only to find out it isn't. I have had it happen far too many times. If it is the O2 sensor, it sounds like it is probably shorting it's hot or return wire to ground. Since it is a heated sensor, it has power, ground and the return. I think that if the hot wire was shorting to ground it would blow out a fuse rather than loading down the system. But then again, maybe Ford never figured on that happening so maybe it isn't fused. It seems possible that if the return line was shorting to ground or power, it might cause enough of a load to bring the rest of the circuit down. Make sure they don't overlook the wire harness from the faulty O2 sensor all the way to wherever it ends! Your wire might have worn through exposing a bare wire to your chassis.

 

[aldive]

Well, I am back running; for how long, who knows.

The new O2 sensor was installed and the voltages are good now. The computer shows no codes and that all is well.

Fingers crossed....
