At idle, should all four have fuel flowing, or just the front two? Mine sounds like a jet engine, but no fuel out of drivers front (or rear two) at idle.

Depends if you have it set up as 1:1 or progressive. Also depends on the model of Sniper.Comment

Yes, the Sniper EFI operates all four fuel injectors with a 1:1 secondary throttle linkage. See "Progressive Throttle Linkage" in EFI Parameters.May God's grace bless you in the Lord Jesus Christ.

I'm using the progressive linkage, and have it set at 47% where the secondary blades start to open.Comment

Then only the two front primaries will inject fuel at idle.May God's grace bless you in the Lord Jesus Christ.

How do you access these connectors to check the front panel on the Sniper?Comment

Post # 12 has a picture: https://forums.holley.com/showthread...900#post231900. You may want to read the entire thread. The injectors are accessed from the sides, not the front or rear.Comment

My passenger front wasn't squirting. I swapped the left and right front injectors, to confirm the injector was bad or not. All four injectors needed the pins aligned with the receiver inside the plug. Then I added a zip ties to make sure it doesn't come loose. All four are working correctly.
