CDR0 -sorry for my typo

---update!!!! I said heck with it, made a starter switch out of

--push button switch /normally off type
--12 ft of lamp cord
--four crimp lugs, which I soldered the + lead to the starter connections. one lead to + one to - , ran the switch up through a plug in the firewall upper left side near the hood hinge where the brake harness plugs in, attached the push button in place of an old aftermarket alarm rocker switch. To the left of the steering wheel. Turn key to "run", hit the button, and it STARTS. Ran the MM all through the countryside, Runs fine, As I continue to diagnose the "no crank with ignition switch" issue.

Zombie Marauder is alive and roaming the streets !!!!!!!!!!!!! Fear the Dark menace....... not going a whole summer Marauder-less.....

I also picked up a Hemi Challenger...funny how taut and SMALL the Marauder seems compared to the beauty Pig Challenger. MM is like a BMW sedan....Challenger : Which out weighs the MM by 200 lbs...

now to tackle that fuel tank pressure sensor...

CDR0 is a truck calibration for a 4r100, it would require some significant code changes to run a marauder correctly, surely that cant be what you have.

[Agent2006]

I cannot type. Just can't.

CRD0 ---MPC-198 - 3W3A-12A-550-CA /6WCWP198A01-AA ---was what I plugged in and didn't run, before I chased some wires

CRD1 -MPC-198 - 3W3A-12A650-CB/6CWP 198A03-AA - is what is in there now with matched key, won't start with key, but will run, no CEL, ABS OK, runs great.

[decipha]

thats odd it should run on either pcm as they are both identical for all intents and purposes

[Agent2006]

If the key doesn't matter, then it was the cleaning of the grounds, etc...that made the difference. (I've had lots of Fords, it seems they tend to have ground issues, not a show stopper or a reason to be anti-Ford, but something to monitor. ) Or that CRD0 PCm had issues. Eventually I'm going to swap them around and see what works and what doesn't...for all of us to have as a future reference.

found this while searching for a problem I have.
Replacing PCM only — E type PATS
If only the PCM is being replaced on a PATS control function type E vehicle, two keys need to be programmed into the PCM. This requires a scan tool with capability to program PATS type E keys, or a CARDONE Flash2 All-Makes Reprogrammer with Ford license and subscription to www.motorcraftservice.com. The tool and software used will give specific instructions to follow. The general steps are listed below.
1. Cycle key 1 to RUN
2. Enter Security Access on PATS control function module. (This takes 10 minutes).

3. Select "Ignition Key Code Erase"
4. Disconnect tool and leave key in RUN position for 20 seconds
5. Cycle key 1 to OFF, then RUN, and back to OFF.
6. Cycle key 2 to RUN, then OFF.
7. Start vehicle.

^^ that doesnt apply thats for reprogramming a key or reprogramming a new pcm pats code

all 03 marauders have the same pats code and all 04 another. Its similar to what ford did with setting all 96 cobras to the same pats code.

New ignition switch from Advance Auto...
TEST 1 - CRD1 PCM, CRD1 Key = normal PATS light (solid red then goes out) NO CRANK. Starts with remote starter push button switch.
TEST 2 - CRD1 PCM, FDH2 Key = fast flashing PATS light, NO CRANK. Still Starts with remote starter push button switch! FDH2 was the original PCM type.

stay tuned for further testing....

TEST 3 -CRD1 PCM, CRD1 Key = normal PATS light (solid red then goes out) NO CRANK. swapped back in old ignition switch. STARTS WITH KEY!!!

$#@#$%^!!! - Advance Auto, brand new $21 dollar "BWD" brand ignition switch. That's what you want when doing a difficult troubleshoot. New parts that don't work right out of the box.

TEST 4 -- original rebuilt PCM, original key = STARTS/RUNS. Done. Fixed. woo hoo

[Agent2006]

30 miles of country roads and some highway blasting. Still runs great. Summer time is Marauder time!!!! AC I fixed a month ago still blows cold.

[decipha]

yeah always best to stick with motorcraft parts sounds like they gave you the wrong type ignition switch

[Fastbob]

That's why I never ever use aftermarket parts unless I have to.
