Do you have a Check Engine Light (CEL)?  Have you checked for codes?  Are your gauges normal for the 5 minutes it's running?  Why was all that other stuff changed?  Was there a reason? 

 

I think 1994 was the last year of OBD1 so the amount of info available will be more limited, but it should be easier to work on too.  See if you can borrow a code reader.  Most auto parts stores have a code reader they will loan you.  If yours is OBD1, it probably won't be enough to tell you the exact problem, but it should get you on the right track.
