### ⭐⭐⭐⭐⭐ Perfect

That's good

### ⭐⭐⭐⭐⭐ Zero Issues
*by R***Y on November 8, 2024*

Car was sitting for a prolonged period. We replaced fuel pump that was literally disintegrated. Injectors clogged with varnish from fuel. Installed these and it fired right up with zero issues. Customer happy, we are happy.

### ⭐⭐ fuel pressure bleed down after sitting (2006 GMC Envoy) 4.2
*by L***Y on July 4, 2024*

Prior to replacements kept getting miss on #6. Unit started right up and ran fine when #6 wasn't missing due to the amount of work involved decided to replace all 6. Completed and allowed to prime and it started fairly quicky. Runs great. Inspected for leaks and found none. mpg increased greatly. After test run for mpg to recalculate Gained 6 mpg. When it sits less than 10 min it starts very quickly now. After it sits for 30 min or less takes alot more cranking for it to start. Any longer than that the ECM times out before starting. I have to try again before it starts. Suspected i may have hit the camshaft sensor on belt removal. Replaced and same. inspected oil for fuel and none found. Will monitor. I really hate to say it but looks like I'll have to do all that work again with a higher quality set of injectors. ITS ONLY TIME. WORK AND MONEY. update 7,5,2024 now its just annoying. dont want to replace starter also. spend more money and buy quality. update 7,14,2024 replaced all and fixed issue. very happy with new brand injectors i was refunded by amazon. suggest (a-premium brand)
