Question about 1984 Ford Mustang

2 Answers

No power from ignition coil

I have a 1984 Mustang with a 302ci. motor out of a ford f150. I recently took the motor out and rebuilt it. I dropped the motor back in and it wouldnt start, it was getting plenty of fuel to the carb but it doesn't seem to be firing right. I eventually found out that there was no power coming from my ignition coil, and the coil is still good. I disconnected the + and - wires going to the coil and cleaned them up and reconnected them better than before but still no power. I have asked for help from a lot of people including mechanics and everyone just said it sounds like a bad connection somewhere but no one knows for sure. Could it be a bad ignition control module? please help. Thanks

Ignition control module must be tested but is most certainly at fault

*UPDATE* 1984 Mustang Won't stay running


Hi

You need to check if the Idle control jets are set properly, these are the 2 screws near the base plate on this type of carburettor.

Screw them fully in, then on the primary side screw it out 2.5 turns.
On the secondary side screw this out 1.75 turns. This should get your idle up.

If this dosn't work then you have got problems with the idle jet system which means you need to pull the emulsion tubes out and jets out to clean them.

Also check that your Idle screw is screwed in enough to allow the throttle to be open enough to idle.

Hope this helps

Thanks

I have a 1984 Dodge d150 4x2 truck. I was driving down off the highway and i lost all power. i thought it was the fuel pump, i replaced it and gas flowed better. i started to drive again and i lost power...


have you checked for spark? check all the leads going to the coil from the battery and from the coil to the distributor, if any are loose or faulty it will cause you to lose all power, also check the terminals.

1984 mustang overheats


You need to describe a bit more about the problem. How fast does it heat up? Does it only overheat when you are at idle or when driving? Any recent work done to the car.
Engine size?

Why do you only have spark when ignition switch is turned from start to run on 1978 ford mustang?


I presume that you mean power out of the switch when the switch is in the run position and not the start position, correct?

The situation can be understood by knowing that an ignition coil needs to run in the 8 to 10 volt range. To acheive this, there is a ballast resistor that drops the voltage, durning normal running...This is the circuit that is fed with power from the switch in the RUN position...

During Start, system voltage drops, as you can imagine, with the load of the starter, during this exact time, the ballast resistor would not output enough voltage to fire the ignition, SO, there is a bypass circuit, actuated during starter engaugement, that feeds full battery power to the coil. this bypasses the ballast resistor, and provides enough voltage for the coil to work.

One of the wires on your ignition feed is possibly wrong, causing the engine to switch off when leaving the ignition.

Key lock ignition


Remove the steering column covers and you'll find the electical switch to the ignition. You'll find a rod that activates the switch from the lock and tumbler. Check for anything broken between the two.
