Question about Ford F-350

1 Answer

I have a 1999 f 350 7.3 diesel, the o/d light is flashing, and it is having spuratic shifting.

I am mechanically inclined and have gotten this far: it is not the speed sensor i took the one off this truck and put on my other 350 and it was all good. i found that i have no ground running to the sensor, when i tested the two wires going to the sensor i have power in both of them, on my other truck i do not. i checked the continuity of the two wires starting from the first plug coming out by the pcm all the way to the plug at the sensor, continuity is good. i dont know exactly where the wires go after the plug towards the pcm. can anyone tell me what my next steps should be? or where those wires go before that first plug in. thanks

Sounds like you have some EGR ports clogged up, remove the intake and look at the egr ports all but
#1 cyl port will probably be at least partially clogged, hope this helps

SOURCE: 1996 F-350 7.3 Powerstroke , truck is running good

Blow by is what you are describing coming out of the oil fill cap. A little is normal, it all depends on the internal condition of the engine. I would not be to quick to say that you have glow plug issues. I would look at replacing the cam censor on the 7.3 engine there is a recall from ford for this on some model year 7.3 liter diesels

SOURCE: 1994 f-350 7.3 turbo diesel.tach reading 0 rpm's at idle speed.

yea the 93 to 95 trucks never had a tach that works very long
and first the Tach does not make the od light blink or ck engine lgt
the crank trigger does this little thing is located right in middle front of engine between the vac pump and pwr steering pmp looks like a brass bolt with wires comming out of the back of it costs about 30 bucks (don't forget the locktite blue)
now that should fix the od lights and the ck engine but it may not fix the tach thats done in the tach driver module on back of tach in dash
you can replace this but my vote it's too expensive I did mine just fine with a after market one(50 bucks), bolted it right in front of old one, it hooks up super easy gets it's signal off the alternator stator

im sort of suprized it starts ok with a bad crank trig (eec needs to see +50 rpm to start fuel flow to injectors )

any good shop with a eec scanner can see this in just seconds

SOURCE: 99 Ford Escort ZX2 Speedometer/Odometer doesn't work

I'm sorry, I have to ask, this is an automatic right? That out of the way, Does the trans shift different when you drove it with the Vss unplugged when you had the ohm meter on it? 8.5 volts? Something sounds wrong here. I'll have to look up the wiring diagram before I can say thats a bad reading but it should be battery voltage (14 volts running) or 5 volts?

Truck has no power an will not release key from ignition

Any warning lights, check engine lights, codes or security/immobilizer lights flashing? I see the TIPM (totally integrated power module) fail a lot on these vehicles. Its basically a fuse panel with relays and fuses under your hood. They get corroded, sometimes wet etc. Locate it under your hood, if you are mechanically inclined feel free to check it out as far as plugs, wiring, pins, fuses and relays. Any more info will help us help you. Please Advise,

Trimming belt replacement on the Toyota 3c diesel engine

If you are not mechanically inclined, you should not replace this timing belt, as it is not an easy task. I'd recommend having a qualified mechanic do it.

Misses badly when accelerating or under a load. shift out of overdrive on incline due to power loss

Have you checked for codes?

Any dash lights lite?

Any testing done so far?

Have to do something then tell us,can't
guess and don't have the car to drive.

You most likely have ignition issues,if the
engine is hot & your going up hills

It down shifts based on shift strategy & vehicle
speed & many pcm inputs from sensors

Could be egr issues

Do you ever do any preventative maintenance?

What it mean when my honda civic 1994 take its time to pull off or when im at a red light then it turn green it take its time to pull off , it all happen after ii got into a car crush

A car crash chould have damaged anything as far mechanical. The question is does it run well when its not only taking off? Mabey your engine has a power issue and when your Transmission connects to the Flywheel during take off from a stop and go. Power issues could be mechanical or a lack of the sufficient Air/fuel ratio. Your best bet would be to have a mechanicaly inclined friend to take look at it or do some research. OR it could be worn clutch if your engine has trouble catching up RPMs during shifts. :D

My '96 Suburban 1500 4x4 won't shift into 4 wheel drive. When I push the button for 4 Hi the light just flashes and stays in 2 wheel drive.

the electric shift motor on transfer case is bad, replace and it will work great. if your at all mechanically inclined you can do this very easy. before unbolting motor disconnect battery to reset computer install part, should only take you 15 min maybe then hook up battery and you will have 4 wheel drive again. good luck

1992 Ford F250 Diesel does not engage in any gear including reverse. Any suggestions?

there is a part of the linkage in the steering column,that wears and or breaks,a steering colmn specialist can check this for you and replace it if that is the problem
if that is not the problem, it sounds like you need to take to a transmission mechanic.QUESTION: is the overdrive light on gear shift flashing/ if it is flashing, the problem is definetly in the transmission,not the linkage

Hard shift from 1st to 2nd, and nothing in drive.

It sounds like a Solenoid problem. It might also be a clutch pack. If you felt like cracking it open to take a look, you might be able to do the rebuild yourself because there are ample parts available, but you might be better off just finding a new used tranny.

My toyota camry has a noise like a diesel truck ever since i hit a curb it sounds like a diesel truck engine is it dangerous to drive it like that what can it be do i stop driving it

If your not to mechanically inclined i would take it to a mechanic and have them check it you may have knocked it out of time and that would make it run very rough and also cause damage to the engine.
