TFI and PIP are common problems with this distributor engine. If you end up doing a motor swap down the road, be sure to use the original eng. harness(es) from your 93, not the donor motor.

I hear you, I just want to hear this thing, fire, pop, whatever. If so, I'll do wires, plugs, water pump & belt. The plugs looked good enought for the tests I'm running thru at the moment.

Hi, another update. I replaced the fuel pump in the tank. Pressure is now
reading 38. I put in new plugs & wires. Then my back went out, after a
month and a half, I'm back tinkering. Not a hint of trying to start, spins fine,
but no cigar. My next thought is the computer (brain box). Where is it? I haven't looked yet, heard it is behind the glovebox? and could this be the culprit? Or, should I look into the CCRM next?

Should be behind the glovebox. A little tricky to get to.

I'm not sure if it could be the culprit, but snatching one at a pull-a-part and swaping it in won't cost a bit of nothing. In most cases I've seen, they go out slowly, causing all sorts of problems, but never just die all at once.

Thank You Roach.

I want to pull the old one first to see the #'s, then hit a
boneyard as you suggested.

So, you replaced the TFI. Did you get a Motorcraft or the cheap junk one AZ sells? I have seen several of these pieces of AZ junk bad out of the box. The TFI is only part of the ignition system. The PIP (profile ignition pickup) in the dist is the second part of the system. PIP determines base ignition timing as well as sends RPM info to the PCM. PIP goes bad just as often as TFI does.

Here is a quick test for the PIP: Instead of listening for the fuel pump to run, use a test light between the fuel pump 12V feed at the IRCM (blue / red stripe I THINK) and ground.
Turn key to run. Light should light for 2 sec as the pump primes. Now crank engine. Light should light as long as engine is cranking is the PIP is good and sending an RPM signal to the PCM.

Hi again, sorry about the time delay. It has been a fun holiday. I had a 04'
Jag with 28K that got totalled (no one hurt). The Taurus has been on the
farthest burner back. Anyway, before the holidays, I bought the TFI from
RockAuto. I also installed a rebuilt distributor with new PIP. I don't seem to
be getting any spark now???

So currently it cranks, you have fuel pressure at the rail, but no spark?

Did you check the fuse for the ignition coil and module (10A) under the hood? Make sure you are getting power to the coil, PIP, and ICM on the red/light green wire with the key on.

Will definitely double check. THANKS!
