RELAY #'s for; Fuel Pump, MAf Burnoff, MAF Power, MAF Sensor, ECM & PROM
1988 IROC-Z 505l TPI w/AT. It was built in Van Nuys CA USA for Export to Canada.
What are the replacements numbers NOW as most likely original numbers are discontinued?
Problem is trying to resolve a intermittent SEL. There is no change in engine except light comes and goes. Sometimes it's on at start-up and sometimes it's not. Can come come on while driving and later it goes off. Throws a code 34.

I have a bunch of the original used relays laying around, as I have replaced them all with the modern version, small square ones, four or five pin as needed. I have not had an issue using them but the connector will need to be changed. Good quality replacements using a diode across the contacts are more reliable.
