Fuse location where is fuse for the check engine light? It is not working acording ot DEQ inspection. Wonder is it is fuse>

Description

*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine start ability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.

Have a short. This procedure may help out. Need test light and volt meter.

1. Disconnect C104 and see if the Red (RD) wire out of the Constant Control Relay Module (CCRM) (pin 12 and/or 24) is shorting to ground, to verify which side of the connector the circuit is shorted.

2. If the RD wire no longer indicates a short to ground after disconnecting C104, inspect the engine harness feeding the injectors, Idle Air Control (IAC) solenoid and Canister Purge (CANP) solenoid for chafing against bare metal on top of the engine.

3. If the RD wire still indicates a short to ground after disconnecting the C104 connector, inspect the harness to the secondary air injection solenoids, EGR Vacuum Regulator (EVR) solenoid, Mass Air Flow (MAF) and Powertrain Control Module (PCM) for a short to ground.
INFO Tip C104 is a 42-terminal connector located at the rear passenger side of the engine, near the A/C accumulator.

Hi Luis
Some Chevrolets have two fuse panels. One under the engine hood,and another in the side of the dash or under back seat...check this,and if so,recheck those fuses acording to the diagram on the lid. 2nd....check for short to fuse panels...good luck

there is a bulletin at gm site in regard to this problem. check the wiring near the parking brake ratchet teeth for damage, also check under the drivers seat where the seat bottoms out wiring could be pinched there or the drivers side door sill.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1734688&psdid=1058&evc=sm#ss1-1734688">Condition/Concern:

There have been reports of either the MBEC 1 or LBEC 1 maxi fuse blown intermittently and unable to locate a short to ground.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1734688&psdid=1058&evc=sm#ss2-1734688">Recommendation/Instructions:

If after normal diagnostics no shorts can be found the below items have been reported:

1. <LI type=1>"MBEC 1" Maxi Fuse 50 Amp (SI Document ID # 1242532). If no shorts are located on circuit 642, inspect circuits 1340 after the "Rt Door" circuit breaker 25 amp and circuit 1440 after the "Seat" circuit breaker 30 Amp (SI Document ID # 1242687).
   • Inspect circuit 1340 shorted to ground near the right I/P support bracket.
   • Inspect circuit 1340 or 1440 shorted to ground on the support bracket for the I/P relay block.
   • Inspect circuit 1440 shorted to ground under or in either front seat.
   • Inspect circuit 1440 shorted to ground near the parking brake pedal assembly. The short may only occur if the parking brake pedal is depressed.
   
2. "LBEC 1" Maxi Fuse 50 AMP (SI Document ID # 1242532).- If no shorts are located on circuit 42 inspect circuit 1240 after the "Lt Door" circuit breaker 25 amp (SI Document ID # 1242687).
   - Inspect circuit 1240 shorted to ground near the parking brake pedal assembly. The short may only occur if the parking brake pedal is depressed.
   

Note: Replacement of the circuit breaker is needed if a short to ground is found on circuit 3, 1240, 1340, or 1440.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Sounds like the wiring is adrift behind the socket ,Now why isnt a probe put up the exhaust to check the emmisions i wonder where the engine is then revved to 2500rpm and the gas analizer read ?

First, Please review these articles:

Where's The Fuse?

What Else Could Be Wrong?

Then to answer the question you asked...

There are actually three fuses involved in your cruise control system.

> The first is the "Cruise Control, EAT ECU" fuse. it is Fuse #4 in the Underdash Fuse And Relay Box. it is a 7.5 Amp fuse. This fuse also powers the gauge assembly, the alternator control circuit, the Radiator Fan Control Module, the Intake Air Bypass Control Solenoid Valve, The EGR Control Solenoid Valve, The EVAP Canister Bypass Solenoid Valve, the EVAP Canister Vent Control Solenoid and the Heated Oxygen Sensor Heater circuits. If this fuse is blown, the engine will not idle, The alternator will not charge the battery and the transmission will not shift properly. In general, a whole bunch of stuff will not be working.

> Next is the "Backup, Metering Lights, Turn Signals" fuse. It is Fuse #1 in the Underdash Fuse And Relay Box. It is a 10 Amp fuse. As you can tell by the description, your backup lights, dash warning lights and turn signals will also not be working if this fuse is blown.

> Last there is the "Stop Light, Horn" fuse. It is Fuse #30 in the Underhood Fuse And Relay Box located at the right rear of the engine compartment. It is a 20 Amp fuse. As you might guess, your horn and stop lamps will also not be working if this fuse is blown.

first is up you octane with an adative or tank of has. the next would be to inspect your rotor cap for crac ks/ scale build up. if showing a lot of build up on the contacts replace cap and rotor button. Those ate the easiest and cheapest improvements. the octane boost reduces the misfire due to detonation

The fuse is also listed as the "IOD" fuse. ( Ignition off draw) This will be a 15 amp fuse located in the "IPM" module which is the black fuse panel in the engine compartment with the snap on lid located along the driver side fender. Open hood, prop it open and check with a test light or pull out and do a visual inspect.

check each of the terminals of those bulb you mentioned. wonder if there's a relay associated to this circuit, check for short if this is the case. remove all the light bulbs [of course - the dash may not be necessary (it's a PITA) & let's hope that it's not the culprit]. visually inspect those bulbs & replace if something unusual. put back the relay if it has no short, turn on the switch, let's hope the dash lights up & it won't blow the fuse anymore, otherwise look for uninsulated wire touching the chasssis or ay metal part of the car. you may continue replacin the bulbs.
