Question about 2005 Ford Mustang

3 Answers

Wife was driving car and she said it felt like the car lost power and the speedometer quit working. The car never died and then it regained power and she was able to drive car home. The 97 Thunderbird with a 4.6 starts fine but the speedometer does not work, the overdrive light blinks on and off and the service engine soon light is lit.

Most likely faulty trans computer. not sure if that year has the electric instrument cluster or cable. but if its electric, the speed sensor on tranny went bad and it wont work until the sensor is replaced. if its a cable, the cable could have broke or seized up

I would drive the car (slowly, since the speedometer is inop) (lol), to an autoparts store and have the fault codes retrieved from the computer. Most autoparts stores will use a scan tool and get the fault codes at no charge. That will help narrow down the search for the pesky problem. Hope this helped.

1996 camry lost speedometer and a/c while driving. Put in new battery and alternator, still no change and now car just lost all power while driving . What is wrong with car?


lost speedometer, what does that mean 0mph at 50? ??????
YES, CHECK all fuses first. all cars, for any electric issues.

A./c lost, (ok there are 6 things that cut A/c some are normal)
one is HVAC dash blower fan must blow or AC brain cuts A.C
this prevent ICE up. (normal)
please:
why guess? please stop guessing and throwing parts and cash.
what does lost all power, driving mean.???
lost engine power (cant drive)
or lost all electric power (a prime reason for EFI to die , for lack of 12vdc electric power)
does lights die on the car, at the moment of problems?
Dash cluster , head lights, any lights.
does engine STALL? (0 RPM is stall) 300 RPM is bad idle.
800 RPM is normal hot idle, never less.

if this is just and engine power issue, (cant drive at all ,or only slow or
slow up hills?)O
my car will not move fast,? in any gear? and transmission don't slip
and no DTC scan codes (checked and smart to do first)

I'd be all over fuel pressure. this is a $20 gauge , that must be connected to the fuel rail to read pressure.
28psi is minimum for all cars.
if i knew what engine was in your car, id look yours up
alldata.com has this info.

the ecu can not report wrong fuel pressure, it cant
so is always and issue, with total engine power loss.
so is skipping 60,000 mile FULL TUNEUP's

if you need those charts they are easy to get. for any car.

tell more get more.... regards

99 Nissan pathfinder le. I was driving and lost all power (lights, dash lights, hazards, everything). I had the alternator tested at auto zone and it was putting out +14. I replaced the battery and it...


You are throwing away money by replacing g parts that are likely just fine. Check for an ecu relay. My wife's 06 has an IPDM/ecu relay issue that will cause the vehicle to just die. It gets corrosion inside the contacts and cuts power to the computer. I had already purchased a spare for a couple dollars. Wife was close to home and car died, started back and was acting up. Swapped the relay in about 2 minutes and no issues since (several months now). Sometimes a small part can cause big problems. You can't just throw money at everything hoping to fix it. You need to do some research and troubleshooting.

Too early I think to have the automatic collision shutdown system. These can be troublesome Had a car that wouldn't start after the lady slammed the boot shut.
Are you using the original ignition key supplied by Ford and not a cut copy ?
