94 Cobra Not Running...working Thru Checklist...need Help

[TX_Snake]

I copy/pasted the checklist and printed it off. I've been working off of that. Car has ran decent for the last few days I have had it, but Tuesday evening the eng lost all power and it stopped running.
Stock 94 Cobra, has MSD coil and dist. cap/wires. OEM everything else.
Here is where I am at.

There are acorns under the intake, like a squirrel has been living under there and lots of wires are chewed up.

I found the TFI module blown. One side was split open and had its guts pushed out. Replaced TFI module, car fired up and ran about 1min before the new TFI literally went up in smoke. Looks like the wiring to the PIP sensor is bad, like I have a short in the eng harness somewhere, or the ign coil (a MSD blaster? All red, twice as big as oem coil) is over powering the system?, or there is a bad Hall effect sensor in the distributor?

PIP sensor gets voltage to both sides of the plug, shouldn't it only have voltage to one side?

Can the ign coil over power the system blowing the TFI?

Anyone had a similar experience?

My OEM service manual isnt here yet so I'm kinda guessing on what to do next. I am going to jump the wire from the PIP direct to the TFI to bypass the harness.

Fix or replace your engine harness wiring first.
and replace that tfi/icm.

Fried another TFI module today, no opens and good grounds. Could a bad PIP/distributor cause this problem?

Got it running! After almost 2wks at the shop I drove it home tonight. Thanks for the help guys, your input helped me get a handle on this issue and get it corrected.

2nd day after I bought the car, it stopped running while driving home. Towed back to my shop and started looking into it the next day. found a TFI module completely fried, side melted out of it. Started tracing wires, checking resistance/voltage, grounds, etc. More I dug into it more I realized I had a major wiring issue, a squirrel had been living under the intake judging by all the acorns/berries/insulation there....and chewed up wires. I ran out of ideas, so I had a electrical specialist come out before and after I swapped injector wiring harness. He then checked/rechecked all grounds/circuits related to that harness. found the PO had wired the fan into the CCRM to be on all the time as soon as you turned on the ign. This was the root cause of the issue. As soon as the wire was disconnected, the fault was gone, reconnected wire, fault was present. buttoned the car back up, broke, then fixed, some vacuum lines, re timed (swapped distributors thinking it was a bad Hall effect sensor), and now it runs great. I get to finally wash it tomorrow and see how well it will clean up. Thanks guys for the help, I appreciate it.
