Causes

Open or shorted injector circuits on bank 1
Faulty fuel injectors (shorted coil or internal failure)
Corroded or loose injector connectors or wiring harness
Low or missing injector supply voltage (fused power, relay, wiring)
Faulty ECM/PCM driver circuitry for injector outputs
Poor engine or chassis ground

Symptoms

Malfunction Indicator Lamp (MIL) illuminated
Rough idle or multiple misfires on bank 1
Poor acceleration, hesitation or reduced power
Hard starting or will not start in severe cases
Increased fuel consumption or black exhaust smoke
Possible stalling or irregular engine behavior

What to check

Read and record all stored trouble codes and freeze-frame data; note conditions when code set
Visual inspection of injector connectors, wiring harness, and ground straps on bank 1 for damage, corrosion or disconnection
Verify battery voltage and charging system health
Check injector supply fuse and relay operation
Back-probe injector connector pins to verify supply voltage and switching signals while cranking/idle
Measure injector coil resistance for each injector on bank 1

Signal parameters

Injector supply voltage: approximately battery voltage (~11–14.5 V) with ignition ON
Injector coil resistance: typically in the range of 1–20 ohms (varies by injector type; check OEM spec)
Control signal: pulsed ground (ECM switches injector to ground) — pulse width varies with load (approx. 1–20 ms depending on conditions)
No short to ground or short to battery on injector control circuits when measured with wiring harness connected
Cranking/idle injector pulse frequency: varies with engine speed; verify using scope or lab meter

Diagnostic algorithm

Capture codes, freeze frame and live data; note any other injector or misfire codes.
Perform visual inspection of bank 1 wiring, connectors, and grounds. Repair visible damage before electrical tests.
Verify battery voltage and check fuse/relay for injector power. Replace blown fuse or faulty relay and retest.
With ignition OFF, unplug bank 1 connector and measure injector coil resistances at the harness side and compare to OEM specs. Look for opens or shorts.
With a noid light or oscilloscope, back-probe each injector connector while cranking/run to confirm the ECM is commanding pulses on the expected pins.
If injectors show correct drive signals but do not function, bench-test or swap suspected injectors with known-good injectors from the other bank to see if fault follows injector.
If drive signals are missing or abnormal for multiple injectors, check continuity between ECM injector driver pins and the injector harness, and inspect for shorts to ground or battery.
Check and test ECM grounds and power feeds; repair any wiring issues.
If wiring and injectors test good and multiple driver outputs on the ECM are faulty, consider ECM replacement or repair following manufacturer procedures (confirm with manufacturer service info before replacement).
After repairs, clear codes and perform a road test/functional test. Re-scan to ensure the code does not return.

Likely causes

Damaged wiring harness or chafed insulation on bank 1 injector circuit
Corroded/loose multi-pin connector at the injector bank or fuel rail
Failed injector(s) with low or no coil resistance (short) or open coil
Blown fuse or failed fuel injector power relay feeding the injector rail
ECM driver transistor(s) failed (common when multiple injectors on same bank affected)
Intermittent ground or poor battery/charging voltage at ECM

Fault status

⚠️ Status

Multiple injector failures detected on bank 1 (P1295). ECM has flagged two or more injector circuit/operation faults on bank 1.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-3.0 hours
