RE: 94 tfi module where is it?
yeah, the only other problem ive had out of my 5.0 is my current fuel pump problems. I had to put a new pump in back in October on the side of the road in daytona fl FTL[:'(] but i got home. but it went out again so i replaced it. i think its the pip as it completes the fuel pump circuit etc as when you turn the key on it primes but the pump makes a surging sound and it sometimes does this while driving now. and feels to be lacking a good bit of power now. im at 180k on the vert so a pip problem really wouldnt suprise me.

If so, you might want to get a fuel pressure gauge onto your rail. I have seen a few cars with that same problem. It ended up being a fuel pressure loss problem. The 89 that I diagnosed with that issue, had a small hole in the rubber hose between the fuel pump, and the sending unit... IN the tank!
so even though it was "leaking" fuel, you couldnt tell b/c it was just leaking back into the tank

when you first prime the engine, does the pump start off at a really high pitch, then drop down to a more normal tone?

no its not high pitched plus that was new with the pump(i know it could be bad) but i relly thinking its int he dizzy/tfi pip circuit
my next guess was a bad fpr but i havent checked pressure yet much less diagnosed the other problem[8D]

RE: 94 tfi module where is it?
Did you just get this mustang or did it just start doing this?
Did we adjust the timing and forget to put the spout connecter back in?
thats what it sounds like......no spout connecter.
the only other thing I can think of is lack of fuel?

RE: 94 tfi module where is it?
where is the spout connector located,i just got it about a month ago and i've tuned it all up and i'm going to get a fuel filter and try that too.i'm just wondering if it could be an internal problem like a cam shaft,as far as i know everything looks to be stock.
