What was the fuel pressure spec? Check for applicable mil codes. Maybe a timing issue?

Were there any mil codes? You may need to check compression? Which relay is clicking?

To check for possible mil codes, you turn the key just till the dash lites come on, no further. Cycle the key on--off, on--off, on, then the mil starts flashing on the dash, you count the flashes to get the codes. Your looking for two digit codes. Example, a code 23 would be 2 quick flashes followed by a slight pause then three quick flashes.

If one of the relays in the diagram is clicking, If you click on the diagram, the picture will enlarge. I just wondered which one it was. If you put your finger on the relay, you should feel the vibration if clicking.
