Reinstalled the factory TFI module, still no spark. If I unplug the SPOUT connector, I get spark but still won't start

You got multimeter ? Take 5 min to test tfi with meter.

Mild hijack. But had heard many moons ago, TFI controls dwell.
Any truth to that?

Made this vid just to show you. This is one of the 5 tests you do with the meter… the top 2 tfis are brand new. The bottom one is a used tested good unit. The top 2 fail right out of box.

Checked all 3 TFI modules. All test good. I'm pretty sure the PIP is no good so I ordered a new drop in distributor

I went threw three,yes three bad brand new dist.from oh oh ohreillieys.
All there pip and modules come from China so its a hit or miss.
I ordered a dragon fire dist.and its been about a year and even though its R.o.c. made its still working fine.
What dist.did you get?

Easy way to test the PIP is pull the distributor, reconnect the TFI and then turn the ignition to the "ON" position. Spin the distributor by hand and you should hear the injectors pulse. If not then that is a clue that it very well could be bad. The aftermarket distributors (even the rebuilt ones) are not near the quality of the OEM ones. If the PIP is bad get a known good one and rebuild the distributor.

Standard Ignition is probably the best new part manufacturer for the PIP if you want to go that route.

My LTD is running the original 84, 3.8 V6 TFI. 5-6 years ago, had a hot start issue and went crazy with every TFI I could get my hands on, and even several remote TFI setups. Old non V-8 TFI ran the best out of all of them (including a brand new Motorcraft, at the time).

So after replacing faulty ignition parts, rebuilding the ECU and replacing the distributor, WE HAVE IGNITION!!!!!. She runs beautifully!!! Just need to tweak the timing a bit.

Wow…….. I came upon this thread, read all 6 pages, on the edge of my garage stool, in suspense of what was to come. Glad it got it started man!!!

Once she started and warmed up I backed her out of the garage, did a power brake test and she spun the tires and left some tire marks in the driveway!!!

I want to thank everyone for your help, information and insight on this issue. My wife was so happy she started crying when she heard it start up for the first time in months. You guys have no idea how much she loves this car. I will post a video soon

I think what everyone wants to know is where you got it from and what brand it is.
