Ford F-150 - 1997-2003 :: 1999 XLT - Crank No Start / Theft Light Flashes A Code Of 1 Then 4 / PCM Not Power Up

I have an intermittent security system issue. I sometimes get a dotted line in odometer and rapidly flashing theft light.

Crank no start. After a time, the theft light flashes a code of 1 then 4. Research gives me the result that PCM did not power up.

Have pulled gauges. Fixed known cold solder joint issue. Checked all connectors and reinstalled. Truck starts fine about 7/10 tries.

I have replaced battery terminals. Removed cleaned and replaced all firewall grounds. Checked harness connection blocks and PCM connector. Made sure all under hood fuses and relays working.

Currently sitting in a parking lot waiting for it to decide to start again. Only one chipped key. Where to look next? 1999 F150 xlt 6 cylinder.

Ford Transmission :: E40D - Shifts Very Hard From 1st To 2nd / Light Flashes On Overdrive Button

My tranny started acting up so I took it to a reputable transmission shop for repair.

Symptoms : Shifts very hard 1st to 2nd. Light flashes on overdrive button.

The following is what has been done at the transmission shop.

Computer failed to read codes. Sent out to rebuild. After rebuild, codes read FIPL needs replace. Done and gives good readout. Trans control replaced, speed sensor replaced, checked all associated wiring and plugs as well as ground. Dropped pan, changed fluid and filter. No parts in pan. Tech says pan and fluid looked good. Replaced coil pack.

After all that, this is what is happening..Clear all codes. FIPL reading good. No flashing light on shifter. It feels like it is shifting from 1st to 3rd, then back to 2nd. Still shifting hard and indicator light starts blinking again. He is going to read computer again. At this point, he suspects a mechanical problem in transmission but is reluctant to remove and tear down.

Ford F-150 - 1997-2003 :: 2000 - Code P0705 - O/D Light Flashing?

To start I was driving to work tonight and noticed the o/d "off" light flashing. it shifted hard one time then felt normal the rest of the way to work. At red lights the o/d light world turn off and about 3 minutes later it would flash again. When I got to work, I checked my code reader which gave me the p0705. I have searched around the net for about an hour and one thing i am seeing is that the fluid is "hot" or that there isn't enough. i have checked it and it looks slightly low like right above the add indication.

The only sound I here from under the truck is a rattle when in drive and at idle, but once I give it some gas it goes away. On they way home that night the o/d light was still flashing but it drove fine just at higher rpm, it down shifted hard one time but there were no other issues. I checked the fuses and they are all good.

Ford 7.3L Power Stroke (1999-2003) :: 4R100 - Overdrive Light Flashes And Shifting Really Hard

I have a 2001 3/4 pickup. Sometimes the over drive light flashes. When it flashes it shifts really hard and sometimes it won't shift into 4th until I mash the overdrive button. Sometimes the light doesn't flash at all and it doesn't have any trouble shifting at all. Is it a solenoid? Or wiring issues?

Ford F-150 (2004-2008) :: No Crank And Red Theft Light Flashes

...Battery is very weak also but had a couple questions...

I started by reading up on issue and 9 times out of 10 people were saying the fuel pump driver module causes the issue...

So I ordered a Dorman and plugged it in...I did not bolt it down...Just wanted to see if it would fix and nothing...

Now stuck on the starter...Top bolt is a huge nightmare.

Would a weak battery and bad starter cause theft light to flash or is my problem elsewhere?

Ford Excursion :: Overdrive Light Is Blinking And Won't Stop

This might be a dumb question but the light for my overdrive is blinking and it won't stop. I tried pushing the button on the end of the shifter but it still blinks. No codes are triggered. This is on my 2000 7.3l 4x4 limited. I haven't check the fluid level yet. Just got home from an exhausting trip. Here is a picture.

With it on ....

With it off ....

Ford Excursion :: O/D Light Flashes / Tranny Shifts Funny Then V10 Dies?

My tranny guy just did a full scan and the ONLY thing which indicated a problem was 'output speed sensor' which we were able to trace back to most likely being caused by a completely hosed driveshaft (I've noticed a driveline vibration). We're going to install a new driveshaft, replace the output speed sensor(s), check for any frayed/chaffed wiring going to the output speed sensor(s) and then see where that leads us (he said something about some computer module in the dash which he's had to replace on several Sooper Dooties).

Ford Excursion :: 2000 V10 - Battery Light Flashes Randomly After Rebuild / Upgrade

So I have a 2000 6.8l V10 that I recently swapped the engine on (reman). While I was doing that, I decide to do some LED upgrades. I swapped out the turn signals, side marker lights, and headlights with LEDs. I added some LED fog lights, and I have a Rigid light bar.

I replaced pretty much everything on attached to the engine aside from the alternator (it didn't give me any problems, so I figured it was good).

When the truck is running with the lights off, there are 6 LED strips running as DRLs, when the lights are switched on, the side marker, turn signal and headlights turn on. When I switch to high beams, my fogs turn on. The light bar is on its own switch.

During the day with the headlights off, I dont notice the battery/charging system indicator light turn on at all. At night, when I flip the headlights on, I've noticed that it sporadically and randomly flash. The flashing indicator light does not appear to be associated with bumps or anything.

It does not seem to matter if I have just the DRL/low beams on, DRL/high beams+fogs, or DRL/high beams+fogs + light bar on. The indicator light comes and goes with the same random consistency regardless of how much power I am sucking from the alternator/battery. The RPM's of the engine also appear to have no effect on when/how often the indicator light comes on...

I drove for over an hour last night, and the voltage gauge never changed, so the battery does not *seem* to be draining (~1 year old Optima yellow). I added an extra ground wire going from the battery to the engine about a year ago (long before this LED upgrade) to ensure a good ground, so I dont *think* the wires are the issue. Is my alternator suddenly going bad? Any higher output ones I could replace it with? Is it a simple fix that does not require a new alternator?

Here are some pics of the lights:

(This was before the fog light install)

These lights only come on when the truck is in reverse:

Ford Excursion :: 2000 FWD - O/D Light Flashes - Tranny Shifting Hard Then V10 Dies?

OK, so my 2000 FWD 6.8L Ex has 128k actual miles on the odometer w/ a stock 6.8L from a wrecked later model truck with ~115k actual miles on this 2nd engine from what I was told by the PO/2nd owner (I have no reason to doubt him and I verified the history with the original owner). So I'm guessing that the 4R100 is original without having ever been rebuilt.

I've had zero issues with the drivetrain up to this point, this truck has always run like a top and been very reliable. This afternoon in drive time traffic the overdrive light started flashing and at the same time I noticed that the transmission was shifting really hard (snapping into the next gear) and not in a good way. I was in stop and go traffic when it was shifting weird like this. At one point I make it up to 55+ and I noticed that the O/D light had quit flashing and now it was shifting like it normally does. Then back into stop and go driving the O/D light starts flashing again accompanied by the weird hard shifts.

Next thing I'm sitting there with my foot on the brake fully stopped waiting for traffic to start moving through the traffic signal when out of nowhere and no indication of anything being amiss the engine quits and I get dash lights including CHECK ENGINE and THEFT. I cycle the key off and then try to restart it. It took nearly 10 seconds of cranking to get it to start up however once started everything is back to normal and I have NO trouble lights illuminated including no O/D light and it's back to shifting normally. I continue on in stop and go and highway speed driving for the next 15 minutes like nothing ever happened, transmission is shifting like it always has. The truck has been turned off once and restarted since that incident, yet no other indications of any issue. What's going on?? What to check into?

Ford Excursion :: No Start - Relays Click Under The Dash And Airbag Light Flashes When Turn The Key

Ok, I have a strange no start issue right now. My excursion won't start. I have power to everything and both batteries are at 12 volts or a bit more but the starter won't engage. If you turn the key to start all that happens is relays click under the dash and the airbag light flashes. It almost seems like the transmission is in gear. It did this twice about a month ago and has been fine ever since until today.
