I bought the spider/regulator asm on ebay and the old injectors were so bad, they were brittle and broke off when removing them.

My symptoms were running rough when first started and sometimes loud backfiring when cranking. From doing research online I found out that leaking fuel pressure regulator will cause the backfiring and rough idling when starting -similar to flooding carburetor but worse. Since mine was a high mileage (app. 200K) 1996 Tahoe, replacing the asm as a unit was a better option.
