Hello,

Well from what you write, you have gotten your dollars worth out of those components!
If you have to change them out, they owe you nothing!
I think you owe it to yourself to be prepared for a total failure sometime.

If not now, the when is coming soon to a theater near you and you, will have a front row seat!

Dan or Pagda sent you a link, to show you that you do have a way to read codes on the car.
It does not require a code reader for you to purchase. It's right there near the back of the drivers side fender. A little back box just like in the link.

Did you look for it and go out to the web site?
It should have some "recent" codes for something, over those many years, unless you found a way to keep the battery a live for 23 years too.

Reading the codes will give you a clue to want might be wrong. It does not print out or speak out, it just blinks a little red LED. You have to, at least, read that part!
I know the link is long in printed information. It will seem daunting, for a first timer who may be attempting and expecting some instant repair answers.

It is made only to give out clues and if you are not familiar with the cars systems, it will be worthless to you. It can help others willing to help you.

We need lots of clues! I personally think, the best you have given us is the 23 years you have been riding for free!
Does the CEL light come on when you turn the key to position 2 for the instrument bulbs test? After 23 years, it might have burned out?

With that tid-bit, I will say you have some serious ignition issues and need to do an overhauling tune up! It's the very first thing, that any mechcanic, is going to make sure that it's in good shape!

You have not mentioned or brought us up to speed with any other "clues" to what condition the car is in.
You would not believe how many brand new Air filters I see on cars, that have been turned into the junkyards! I have a shelf full!

In lots of cases, I don't even get charged the $2.00 for them because, I buy more pricey and important things!
I get good fuel pumps complete with new filters as a unit, compliments of the unknowning, in their many ways, from the previous owners!

23 years on original fuel filters might be a record!
Especially, if the car went across the country and has mileage matching it's age. I'm impressed but don't ask what else I think!

I gave you hint, I'm another person just waiting for a car like yours, nice parts! The insurance companies do the, other stealing, for us in a much bigger way, Crush!

Get back to us with a log book of all types of information and maybe we can stir through it and find a clue in there somewhere.
You have some catching up to do!

Cluelessness is not a good status of mind to be in! Especially for others, you or me!
