Standard Ignition Fuel Injector Connector P/N:S-1797

$60.99

Description

Keep the signal flowing to your fuel injector with the Standard Ignition Fuel Injector Connector S-1797 — the electrical connector that links the engine wiring harness to the injector. It installs as a direct-fit replacement for the 1990-1992 Infiniti M30, 1993-1995 Mercury Villager, 1988-1994 Nissan 300ZX, 1990-1994 Nissan D21, 1988-1992 Nissan Maxima, 1990-1995 Nissan Pathfinder, and 1993-1995 Nissan Quest.

A fuel injector connector carries the switching signal from the vehicle's control system to the injector so it can open and deliver fuel on command. Over years of heat and vibration, the connector body and its contacts can become brittle, cracked, corroded, or loose, interrupting that link.

Replaces a worn connector: swaps in for a damaged, brittle, or corroded original connector on the listed vehicles.
Direct-fit replacement: designed to replace the original connector on the listed applications.
Signs it may need replacing: intermittent injector operation, rough running, or a stored injector-circuit trouble code — if a faulty connector is the cause. Diagnose the cause before replacing.

Interchange: Manufacturer part number S-1797.

Frequently Asked Questions

What does this fuel injector connector do?

It's the electrical connector that joins the engine wiring harness to the fuel injector, carrying the switching signal that opens the injector to deliver fuel.

Which vehicles does the S-1797 fit?

It fits several Nissan, Infiniti, and Mercury applications, including the Maxima, 300ZX, Pathfinder, D21, Quest, Infiniti M30, and Mercury Villager. See the Buyer's Guide tab for exact years.

How do I know if my injector connector is bad?

Signs may include intermittent injector operation, rough running, or a stored injector-circuit code. Have the cause diagnosed first, since these symptoms can have other sources.

Is this a direct-fit replacement?

Yes — it's designed to replace the original fuel injector connector on the listed applications. Confirm your vehicle in the Buyer's Guide tab before ordering.

Will this fix a rough-running engine?

Only if a failed injector connector is the actual cause. Rough running has many possible sources, so diagnose the circuit before assuming the connector is at fault.
