I have a 95 f150 I6 300. My truck was running rough and would not go anywhere and had a terrible idle and would even cut off, i started with replacing the Idle air control, that wasnt it. We then looked at the timing to see it was off. We where going to replace the entire distributor but decided the cost was to much to "wing it" and that not be the problem. So i bought a coil pack. Still wasnt it. We rotated the Distributor to try and time it and it was getting dark so we decided to call it quits for the day. Now im getting spark out of my coil but no spark out of the dist. to spark plugs... It was just running the night before and we where trying to tune the timeing, and now not zip. Has a new cap and rotor too. New wires from coil to Dist. and from Dist. to plugs. We swapd the ignition module with the one from my dads truck and that didnt fix it so thats not it either. Im out of answers and need help bad. Im tired of throwing more and more money at it for it not to be the correct part. Also, we finally where able to get fire out of the cap to the plugs but now its not again.

 

just because you have spark doesn't mean it is strong enough.

Your coil takes in 12v and converts that to a much higher voltage. If that is not happening, I would look at your coil again. The coil can be tested with a volt meter.

When swapping out the TFI module, make sure you use the same colored one. There is a grey one and a black one.

 

Any codes on it?

How to run a self test.

please post all codes you pull, even if it's just the 'all clear' code.

 

I used a grey TFI module and had same number model no.. I will reset my comp and go run codes, its snowing atm so working on it slowly

 

Also the coil is brand new, its even the performance coil and it was all doing good when we wur trying to set the timing 2 nights ago until the next day is when no spark was coming out of Dist. cap and today while working on it it was getting spark, but not starting, and the spark wasnt consistant. Now, no spark out of dist. again

 

Have you put the old coil back on it, since it was running with that?

 

Your 95, even the 300 6? uses a black TFI module.

 

I agree with many of the replies above..

1. Your truck uses a black colored CCD-style Ignition Control Module.
2. I HIGHLY suspect anything labeled as a "performance" coil. Put the old one back in.
3. If you have spark going to the distributor, but not the plugs verify the rotor is turning.
4. If it is turning, perhaps you got a bad replacement cap and/or rotor.

 

WOW.. Yeup, i have a black TFI and of course my dads f150's is grey.. So when i swappd them to see if mine was bad it did noth. ok thanks so much for that info, im going to the parts store to see if they can test my TFI and if they cant ill just buy a new one

 

Got the TFI tested, 2 out of the 6 times they tested it it tested bad. I got a new one. Did not fix my problem. I hooked up my old coil, still did not fix my problem. I took a spark plug out and i see no arc between the diodes on the plug.

 

Put old dist. cap back on and still no spark from it also

 

also pulled a code 45 along with many others. 45 sais coil one primary circuit failure? can anybody explain where the circuit could be failing if ive put back in my old coil that i know works and it still hasnt fixed it?

 

none of these seem to be the issue, put all my old parts back on and got a new black TFI and that did nothing

 

Sorry for all the extra posts but i keep checking more things.. I checked the volts going on the 2 wires going into my coil and its reading on 10.73V with the key in the run position

 

Watch this video, it will show you how to test the system using basic tools to find out where the problem is.
