1989 Ford Mustang Ignition Problem

I am checking on a possible diagnosis for my neighbor who has replaced his ignition components and has fire coming in but not coming out. He is about to pull his hair out.
He has a 5.0l engine.

I have a 1989 mustang gt with no spark from the coil, but the coil is brand new. My car has the MSD ignition box that runs not the coil and the car will crank, and you can smell gas but when I turn the key to start it there is no spark. Please help I'm going crazy!

So does he have spark at the distributor but not at the plugs? I'm not sure what you mean by fire coming in but not coming out. I build alot of these cars.

1989 f-250 5.0 engine cranks but won't start

  1. The ignition system on your 5.0L uses a distributor type system and will include the following components:
    1. Ignition control module (ICM). Depending on the year of your specific Ford, it'll have a inner-fender mounted ignition control module or a distributor mounted ignition control module. hot sure which you have.
    2. Ignition coil. you replaced it.
    3. PIP (Profile Ignition Pickup) sensor. This is Ford's name for the crank sensor and is mounted inside the distributor. The most common name for this component is the pick up coil.
    4. Distributor cap and rotor. you replaced
    5. Spark plug wires. you replaced.
  2. The thing to keep in mind about the ignition system is that all engine cylinders must get spark and the one thing that will stop the ignition system from creating spark on a wholesale scale is a BAD crank sensor.Have you pulled a plug then using some insulated pliers grounded it to the vehicle and turned it over to see if you have spark, that'll tell you alot.takes two people of course.Best of luck and hope this helps.

My 1989 ford bronco will run for 15 minutes then just quit running have replaced fuel tank both fuel pumps and filter it's got 44 lbs pressure what else could it possibly be wrong

have you checked for ignition fire to the plugs after it dies? chances are the ignition control module is getting hot and shutting off the signal to the ignition coil.

I was running this car in my driveway, when it died all of a sudden and will not restart. I find that there is no spark, and the fuel-pump is constantly running when the key is on. Help!

Hello Ford Cobra.
Strange the fuel pump stays running as soon as the key is on.
This is leading me towards a possible relay problem that is also affecting the power relay that powers up the injection system.
Is there power to the ignition coil momentarily as the key is turned on?
If so the power relay is working and will lead to the next diagnosis step.
Keep me informed.

Can't start my 1987 mustang

Inside the distributor car is a small rotor that spins. It may be corroted, causing it not to fire the plugs. They are only a few dollars at a parts store (around $5-$10.) It comes right off.

89 mustang 5.0 starter stuck on

The ignition switch isn't hard to replace. Take the column covers off and you'll have to buy tamper proof torx bits to remove the mounting screws. Just unplug the old switch and plug in the new one. The new switch will have new mounting screws with it. It should only take you 20 minutes to replace it even if you've never done it before. Check the operation of the lock and tumbler as well. It's an easy replacement as well. This one only should take you 5 minutes.
