Ok, heres the lowdown
1991 ranger 2.3
Driving along, truck lost power. No pops backfires, pings, nothing, engine just smoothly turned off as if it was turned off

at the ignition. Check it out. Timing belt is broken. Tow truck home, remove old timing belt, align crank and cam according

to book, replace timing belt. All good so far right? Nope, truck still wont start. Absolutely no spark at the coils. Here is

everything I have tried since then.

Fuel pump is coming on, fuel is present at the schrader valve on the fuel rail

Swapped out TFI module...did nada

Swapped out one of the coil packs...did nada

checked all underhood fuses....good

all 3 relays seem to be clicking (pump, eec, and ignition)

pulled ignition switch out from column...seems to be working fine

crank position sensor seems to be working fine (turn over motor by hand and when the gap is closed you can hear the relay

start the pump)

all grounds seem to be connected, (engine, eec, etc)

Truck is spitting out a code 88, which is supposed to mean DIS, spout, or SAW failure.

Any ideas on what to try next.
Do you think possibly the ignition or eec relay is bad even though they are clicking?
Is there some type of fuse, fusable link or relay that I am missing
If the EEC was bad would it give any type of code?

I am curious to understand how the ignition switch works.
4 positions acc, off, on, start right. Logic would tell me if the "on" portion of the ignition is not working, the truck

would turn over but never start right? Is this a possibility.

I am open to all opinions
Thanks in advance
Andy

 

Are you sure about the code 88, its not listed in any of my books.

 

Ken, what books do you have?

All the EEC codes I have found online have 88 listed as mentioned above

EEC IV uses 2 digit codes

I think the newer EEC5 and OBDII computers use the 3 digit codes

Thanks
Andy

 

I have the Ford manual for 1988 and the emmisions disc that covers EEC-IV. I found this reference for code 88 at another Ford site.

88 Throttle Kicker Solenoid - Solenoids
Variable Voltage Choke relay circuit fault - VVC
Fan Control circuit fault - A/C and Fan Circuits
A4LD - Converter Clutch Override solenoid - Transmissions
Electronic Ignition - IDM, DPI or spout circuit fault - Ignition Systems

 

I had a problem with a 94 giving an ignition EDIS/spout code. My truck would start and run but was idleing rough. I had to replace the EDIS module.

Make sure you have tried and tested everything before changing out because it is about a $100 part.

 

Thanks for the help everyone. Believe it or not, the problem was the module. My old module tested good at two different auto parts stores(tested about 10 times), and passed every time. As well as buying a new off brand model that didnt work right out of the box. What are the odds? So I was racking my brain thinking I had a problem in the wiring harness or something. After I had checked the whole ignition system for continuity and shorts to ground. Once I determined everything else checked out ok, I knew it had to be the module. So just for the hell of it, I went and bought a second one, the truck fired right up!!


Thanks
Andy

 

Glad everything worked out for you. Sometimes things can be hard to track down.
