Hi there I did a 02 longblock swap on a 98 z28,Everything is fine,but having some injector problems.It seems 2,4,6,8 injectors on the passenger side are not operating correctly.It seems like only the 1,3,5,7 drivers side injectors are working.I rented a bulb noid tester deal to check to see if the injector pigtails were firing and they seem to work fine on either side.I checked continuity on the injector control pins from the pcm pin harness to the injector pigtail and they seem to be fine.It seems tho that plugged or unplugged to the injector does nothing.Any ideas?

 

how long has those injectors been dry before the engine was restarted?

 

Just curious about how that matters? And if they have been dry for awhile what you recommend you do with them? Thanks.

 

injectors do not like to be stored empty. They absorb moisture and stick closed. We see it all the time. If they are not pulsing and the plug is firing a noid light. Take out the injectors and boil them in a pot for 20 minutes.. Then see if they work,
