I really feel like my problem is flooding. When I jumper the starter while holding throttle full, it will pop over. Won't stay running. But at least now it'd doing something with timing Set right. How to lean out the fuel?

While cranking, i twisted distributor clockwise. It ran for almost a minute. When it seemed time for it to idol down it died. A code came up PO385 crank shaft sensor b circuit malfunction. Idk what to do at this point. My pride will be wrecked if i have to tow it to ford...

Was going to do compression test. Went to autozone and rented tool. Now engine wont crank, relay just clicks. Checked starter was tight, has good connection. Tried taken it down but the top bolt striped smooth as a baby's ass... Ill have to take the header down to put better tools on it... Taken a break from this for today. Try again tomarow
yo,
Man! This is a Trying day for you and me.
But it will get better soon!
btw Ford describes the Crank Position Sensor as Misfire Detection (MD) Sensor
P0385 indicates that Self-Test has detected a Misfire Detection (MD) Sensor circuit failure.
Possible causes:
-- MD circuit open.
-- MD circuit shorted to GND.
-- MD circuit shorted to PWR.
-- SIG RTN open.
-- Damaged MD Sensor.
-- Damaged PCM.
Start engine.
> Will the engine start?
No: DTC P0385 is not the cause of the No Start.
Yes: Key off.
MD sensor vehicle harness connector disconnected.
Timing Pointer & CKP/CPS (misfire) sensor used only on OBD-II engines. The lower L pulley is a factory idler where the air pump used to mount
Disconnect PCM. Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.
Measure resistance of MD circuit at the MD sensor harness connector and EEC Pin 59 (MD) DG/LG wire.
Measure resistance of misfire RTN circuit at the MD sensor harness connector and EEC Pin 6 (SIG RTN) Bk/Y wire.
> Are resistance measurements less than 5.0 ohms?
No: SERVICE open circuit
Yes: Key off.
MD sensor disconnected.
PCM disconnected.
Key on, engine off.
Measure voltage from EEC Pin 59 (DG/LG wire) to EEC Pins 51 (Bk/W wire, GND) and 55 (Y wire, KAPWR) at the EEC vehicle harness connector.
> Is voltage less than 1.0 volt?
No: SERVICE MD circuit for short to power.
Yes: Key off.
PCM disconnected.
MD sensor disconnected.
Measure resistance from EEC Pin 59 (DG/LG wire) to EEC Pins 51 (Bk/W wire), 55 (Y wire) and 6 (Bk/Y wire).
> Is EVERY resistance greater than 10,000 ohms?
No: SERVICE MD circuit for short to GND or SIG RTN
Yes: Key off.
EEC disconnected.
Measure resistance from EEC Pin 59 (DG/LG wire) to each of the following pins: 51 (Bk/W wire), 55 (Y wire), 71 (R wire), 97 (R wire). Then measure from pin 6 (Bk/Y wire), to 23 (Or/R wire).
> Is EVERY resistance greater than 500 ohms?
No: REPLACE EEC.
Yes: Key off.
Reconnect EEC & MD sensor.
DVOM on AC scale (to monitor less than 5.0 volts).
Measure voltage from MD circuit 59 (DG/LG wire) to GND circuits 51 (Bk/W wire) and 103 (Bk/W wire) at taps in those wires while running engine at varying rpm.
> Does AC voltage vary greater than 0.1 volt AC?
Yes: Replace EEC.
No: Is the MD sensor trigger wheel damaged, i.e., loose or misaligned?
Yes: Replace or service trigger wheel as required.
No: Replace sensor.

Got it! Its running. I burned up a starter and replaced it. Back to just cranking... Then while looking for bullets to blow my brains out, i found my old crusty ignition coil. Figured what the ****. Threw it in, Fired right up. Although i had the MSD coil tested at autozone and passed it wasn't putting out proper spark. Thank you meisk and seabronc for you help and your time. This problem was also noted on another forum similiar problem with MSD coil. Thank all!

Bah, stalled again. That what i get for speaking so soon. After changing coils it started right up. Took throttle inputs. Idoled down. Set base time perfectly. Turned off and on several times. Turned it off to eat dinner. After started perfectly again, Tried to back down the driveway. Reversed about 10 feet then died. Same no start. Changed coils back and forth, wiggled all wires in the area, i dont get it. It seems i have a gremlin...

Started right up this morning, tried to give it throttle, it died. Wont even pop over. Getting closer to figuring this out. I'll try again after work.

Check the inside of the distributor for signs of arching. Look for little lines running from the plug contact to the edge of the cap. It may also be a shorting pickup coil under the rotor.
Good Luck,

Yo,
I am still trying to load the 96 EVTM/PCED.
As a WAG, if the starter relay on pass. side inner fender doesn't click when turning key to start; try jiggling the key/cylinder.

Got home. Wouldn't start. The wires leading into the ignition coil weren't fully seating in the connector. Pushed the plug into the coil, and then pushed the wires into the plug with a pocket screwdriver. Fires right up. Drove around for a while. Seems good now.. Ima put on new plugs,wires,cap,and rotor tomorrow. Should be all caught up on things after that. Cant wait to hit the mud!
yo,
Congrats on persevering!!!

Fails to start again. Broke down in the bad part of town. Leaving wife stranded on the way to work. Drove maybe 10 miles since it's been running. Tested the coil has bat voltage on one side the other side doesn't pulse when cranking. I pulled out that new distributor from autozone and exchanged under warranty. Put the new one in on the side of the road so the timing was off. It drove home to which i set the timing (spout out) 10* btdc. Sounded good so i shut the hood. Later went to leave, no start again. Same symptoms. Ive just read a bunch of forums on autozone distributors. Some changed them 2 or 3 times before getting a good one. This is just the worst.. Lol
yo b,
I got light headed when I saw your last post.
Yes, some distributors aren't rebuilt well
For example.
"...I recently had a problem with my PIP module in my distributor. I bought a Cardone from Auto Zone. I am now on the third replacement..."

"...I had problems with the AZ pick up on my 89 last year I ended up using the old one that I replaced it with not a peep since..." by

cardone Part No. 30-2700
replaced due to bad PIP in oem. truck wouldnt idle with spout in only out. returned due to being defective and got another on one. #2 worked like a charm. by Scotty2hottie
