SOURCE: I need to replace the srs (airbags) 2002 mustang

U can't just do the bags, u will need to replaced the control module/diagnostic module and test and replace any affected crash sensors, all this requires electrical test equipment an allot of field tech experience, also if not done right u can cause the airbag to go off and really hurt yourself.

My 3.8L wont start? I just took it out the Ford house cause they said the problem was the pcm.


Either the dealer turned your car over to a part-swapper "mechanic" who misdiagnosed the problem OR the replacement PCM was defective right out of the box.

How to check pcm, no spark,no fuel, no injection pulse.99 ford mustang 3.8 v6


When you turn ignition key on ( not start ) does the checking light ,light ? Check fuse's for PCM , are they good ? Find a wiring diagram an check power an ground at PCM . Also hook up a scan tool an see if it will communicate with the PCM . That's how you check the PCM ! Also check the constant control relay module , these go bad an they have fuel pump relay , power hold relay , this powers up fuel injectors an ignition system !

95 mustang v6 auto no forward gears but works in reverse had ****** rebuilt and same thing


Maybe your differential is shot and will only allow reverse spin or the transmission was not really rebuilt professionally. Was the transmission checked outside of your car after rebuild? Does your vehicle have a Powertrain Control Module (PCM)? Maybe the module went bad or faulty.

My 2002 mustang gt misfires on cylinder 1 ( cylinder 1 misfire/circuit malfunction) While misfire i get lots of fuel dumping. Loss of power.


I assume your CEL light is flashing. You will ruin your $1000 catalytic converts if you drive it this way. Your cats will turn red hot and self destruct.

You have a bad COP, Coil on Plug (if your vehcile has that system, and it could have damaged your PCM engine computer. Remote chance it's just a plug.

Your injectoris still pumping fuel into that cylinder and teh cat has to over work to treat the unburned fuel.

You did not say if you have a V8 or V6 engine which is important.

NEED FIRING ORDER FOR A 2002 FORD MUSTANG


Ford makes no 3.2 V6. If your Mustang is a V6 it is a 3.8 Liter. The firing order of the 3.8 V6 is 1-4-2-5-3-6

Not all spark plugs firen


You check the right firing order?

1991 Ford Mustang 5.0 liter V-8 HO

Also, need check the PCM for someone short; sometimes this is the reason it wasn't sending a signal to the coil. You have constant power at the coil but the ground signal doesn't fluctuate from on to off while the engine is cranking. If the hall effects switch in the distributor is bad it won't tell the PCM when to fire the coil and the hall effect switch also operates the tachometer. So if this switch is bad the tach and the coil would not work.

Good luck.
