I am here to help.If you are getting no spark and have already tried all of those things-the only thing I have for you is a diagnostic path to follow out of the 92 F150 PCED.Here it is:
[IMAGE][SRC][/SRC][ALT][/ALT][WIDTH]100[/WIDTH][HEIGHT]100[/HEIGHT][STYLE][/STYLE][/IMAGE] CAUTION: Do not connect EEC processor to EEC breakout box when it is used with TFI diagnostic harness.
Note: Engine may start, continue diagnostics.
Thats the best I can do for you.I hope that helps.SMTBob
I don't have any details on the quick test procedure that's mentioned in your text. I've done most of the other tests that you've suggested, but I didn't have some of the measurements you listed for testing the ICM. Also how do you clear the continuous memory?
I've got a buddy with a good Fluke scopemeter and i plan to take a close look at the PIP input and SPOUT signals. on my fluke 77 they're bouncing between 4-5.5 VAC.
So how do i print the text of your answer?
I only know how to clear the continuous memory with a STAR II EEC IV scanner because that is all I have ever used on that year model.You would have to follow the instruction of the particular scanner you are using if it is capable of clearing codes.The only way I can tell you to print the info is to right click your mouse and then click Print on the list of options.Good luck.
The quick test procedures are basically retrieving codes KOEO and KOER.
