How long since a tune-up? Use a gage and check fuel pressure. Are there any mil codes?

Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. To check for mil codes, use a jumper wire between A & B terminals of data link connector. Turn the key just till the dash lites come on, no further. The mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes. The diagram below is a generic GM obd1 data link connector. The only purpose is to show location of A & B terminals.
