First of all --
Hello Everyone!
This is my first post, and it is a question rather than a solution. Hopefully someday soon here I'll have more of the latter, but until then, I could really use some advice.
I inherited a gift 1994 Explorer from my folks and drove it from Oregon to California last week. A couple times during the drive the Check Engine Light came on, but seemed like no biggee. Therefore I know the CEL bulb works.
Now, I'm ready to get it smogged to California standards -- I have changed out plugs, wires, PCV, air filter, fuel filter, oil, etc...........
My first attempt at smog test was that the CEL will not illuminate during ignition test.
Luckily, they were very nice and didn't fail/charge me.
So, yesterday I checked all fuses with voltmeter (incl powerbox), swapped EEC relay with fuel pump relay, and pulled codes (only bad code was user-error 587). Still no CEL.
However, when I was driving to the store last night, the CEL magically worked! Hoorrayyy! Except that this morning, it was not working again.
This morning I checked/cleaned about 4 or 5 grounds I could see in the engine compartment, and checked the power supply (for lack of better name for it) to the EEC. Only half of the EEC gets power during ignition, and I have no way of knowing if the other half is supposed to only get power after start-up (as the truck wont start with EEC unplugged).
Any thoughts would be greatly appreciated!
I really never thought I would WANT the Check Engine light to illuiminate!
Thanks a Bunch,
Jamie
