check engine on and no-one can seem to figure out why, any suggestions or ideas

The debate group at work must have come up with at least seven ideas. Some mechanic will have to plug into the OBD whatever system and look for codes, or get them some other way. It would help a little.

I think you just need a paper clip (bent out) or jumper wire between two of the wires in the under hood test connector, and then count the flashes of the check engine light. Unfortunately, I don’t recall which two pins off hand.

I think that he needs a code reader. 1995 was the first year of EEC-V/OBD-II.

Noboby can figure out why the light is on? Nobody has tried very hard.

Get the codes read. They’ll tell you what the light is on for. Post the codes back here. Someone here can interpret them for you.

It would be a huge help if you could tell us what’s been checked so far, what’s been done, what codes have been found, and any other info you have. We need something to work with here.
