1993 Ford F-150 Repair Question
F150 cranks but won't start
1993 Ford F150 6 cyl Two Wheel Drive Manual 197000 miles
I have a 1993 f150 it died just like the key was shut off? there is no spark or fuel pressure? I tried to flash the engine codes out but there is no responce from hooking up the jumper wire? does any one know which relay in the power dist. box is for the eec? they are not labeled ?
I checked the relays and fuses? I probed the power wire rite were it goes into the eec and it is getting good power and does have a good ground? the coil gets power but there is still no spark or fuel pres.
do u have check engine light on
if not check fuses and relays
relays under hood by the fender .
yah I did that? I even probed rite were the power goes in to the eec and it is getting power all the time thru the orange wire and ignition power thru the red wire and has a good ground? the coil has power but ther is still no power or fuel pressure? I think the ecc must have died? I was just hopping for a second opinion before shelling out $200 bucks for a new one. thanks for the time
These may be hard to see but does this help?
If I need to email them to you and say, put them on a powerpoint slide etc let me know your email address.

I do not believe its the PCM
but you had asked me for its location
u have to disconnected from under the hood by the brake booster
and pull it out from inside by the brake paddle
thanks guys! the diagrams were the ticket, I pulled the ecc removed the cover and it has a qarter size burnt spot in the board? now I just have to figure out why it burnt out before I plug in the $200 replacement? thank you!
Caution its very good you found the problem but it is very important to find why it did burn like this they don't usually fail like what you have described, you have a short that you have to find before u plug in the new PCM in
ALSO CHECK YOUR EMAIL
I HAVE SENT U THE DIAGRAM
I never recieved your diagram of the eec? the one you posted looks rite but is to small for me to make out? were can I get a copy of this? it will probably help me find which area the short in in? thanks
