alright so i was helping a fellow mustang owner today with his car trying to get it started.. he said he was driving down the road one day and it just died..

problem= no spark

it has fuel it turns over great after the new starter we put in today.

things i have tried.

it had an msd box on it i bypassed that to get rid of one possible problem
we put in a new coil
i put my msd distrubitor in it
we tried to put direct power to the coil
put in a new ecu relay

it just wont get any spark.

i am thinking about rewireing the coil i am pretty sure the tach wire -on the coil is the red/green. but i dont know where the coil gets its + from and if i can just hard wire that stright from the ignition?

any other ideas out there please chime in or give me a call 727 364 5835..

ignition switch?

ok so whit i pretty much need to know is which wire off the distrubitor goes to the - and where does the coil get its + from?

Mustang FAQ - Engine Information

I would check here. This is how I tracked down the problem on a 95 that was having the same issues. It ended up being a bad hall effect in the dist. But if you swapped them then that rules that out.

That link should show you the wiring for the coil.

sounds dumb but is it efi did you check ALL of the fuses. and make sure no wires touched anything hot and melted

no i havent checked hot/melted wires. i am going to do that tomorrow. fuses were good

Fuses, grounds, computer or how about the fusible links on the positive side of the soleniod. There are alot of possibilities.

nothing has been messed with i did switch the computer. remember the car was running fine then just died driving down the road.. i am not getting signal or power to the coil so i think i am going to rewire it direct. its the #5 pin on the distrubitor and i need to know where the power comes from? whoever had the car before him had some jacked up wireing so i dont want to mess with their gaggle.

I'm looking in a repair manual now Sean. Try this:
Check the voltage on the positive terminal of the coil with the ignition switch turned to RUN. If the voltage at the positive terminal of the coil is not within battery voltage, check for a worn or damaged ignition switch. If the reading is within battery voltage, check for faults in the wiring between the coil and TFI module terminal #2 or any additional wiring or components connected to that circuit.

The 5th pin down on the module is for the tach.

lol thats right which one goes to the - on the coil?

tan/yellow

The 5th pin down.

Since you don't have power to the coil the ignition switch is probably the culprit. The only power to the coil comes from the ignition switch. That also looks like it ties into the 3rd pin up from the bottom on the ignition module. If there is no power there it has to be either a break in the wiring or a bad ignition switch.

Yea but if the fuel pump is coming on, that also runs off the ignition switch. If you're hearing pump prime, I wouldn't think it's the switch. If you aren't then it's definitely a possibility.

try holding your key to the "start position" and see if it runs. This will allow the ignition switch to read 12v while in crank, but back the key off just enough not to engage the starter, just enough for crank 12v reference to the coil.

My girlfriends honda accord did this last month.. ended up being a bad ignition switch.. It would run fine when you have the key turned to start

But it is off of a different circuit. The wire for the fuel pump relay is orange w/black stripe and the wire for the positive on the coil is red w/light green stripe. They come off two different terminals. It is very possible one spot in the switch is dead. There is only one way to find out. Test it.

i will check that tomorrow thanks darrell. i did do some testing on the dist plug and i belive i had normal 12.xx volts to the plug but i got nothing to the coil side but now that i think about it i believe i was thinking the red/grn wire was ground cause when i tested it as a ground it read voltage so maybe it shorted out on something....

yes the fuel pump cycles fine.

so if it did short out on something do u think i could just tap into the wire coming off the distrubitor?

Don't tap into anything. Find the problem and fix it. Don't rig anything or you are just going to create more problems. Things like this are a simple fix.

on ignition switch.....

Just a guess

Dont call me an idiot or un educated if I am wrong plz................

[e3sean]

where is that located? the ignition switch?
