SOURCE: 1993 gm 454 engine fan belt assembly

Go to www.autozone.com and click on repair info and enter in car info and then click on repair manuals and a manual for your vehicle will come up and it should be listed in that manual. Sometimes the diagram is on the hood of the vehichle rather than on the engine compartment but you probably already looked there... Hope this helps

Can anyone tell me what this is on my suburban?


That is the ODB11 Code Reader Port. When your engine malfunction light comes on, you attach a code reader to that socket and the machine give a P Code. That code tells the problem as stated from the ECM (engine control module.

2006 grand prix gxp 5.3. When you are driving normally it will miss from 50mph and up. When you punch it it doesn't miss a beat. I cleaned the maf sensor and air filter, Plugs were replaced.


It's probably a coil breaking down , have a scan tool hooked up an have misfires checked to see which cylinder is missing .
Ignition Coils
Each ignition coil has an ignition 1 voltage feed and a ground. The engine control module (ECM) supplies a low reference and an ignition control (IC) circuit. Each ignition coil contains a solid state driver module. The ECM will command the IC circuit ON, this allows the current to flow through the primary coil windings for the appropriate time or dwell. When the ECM commands the IC circuit OFF, this will interrupt current flow through the primary coil windings. The magnetic field created by the primary coil windings will collapse across the secondary coil windings, which induces a high voltage across the spark plug electrodes. The coils are current limited to prevent overloading if the IC current is held high too long. The spark plugs are connected to their respective coils by a short secondary wire. The spark plugs are tipped with iridium for long life and efficiency.
Drive it long enough like that (with it misfiring ) the check engine light will flash . This is to warn that a catalytic converter damaging event is taking place . This would also set a DTC - diagnostic trouble code

Where is fuel pump harness on a 2000 escalade


DTC P1351 Ignition Coil Control Circuit High Voltage
The enhanced ignition system uses the crankshaft position (CKP) sensor in order to provide a timing input to the control module. Ignition control (IC) spark timing for each cylinder is based on this input. The control module provides the ignition timing signal to the ignition control module (ICM) to control the ignition coil. Each timing pulse detected by the ICM allows it to energize the ignition coil. A large secondary ignition voltage is induced in the secondary coil by the primary coil. This high voltage is switched to the correct spark plug by the distributor.
This diagnostic trouble code (DTC) will set if the VCM- (vehicle control module ) detects an unusually high voltage on the ignition timing signal circuit.
Diagnostic Aids
Intermittent test -- If the connections and the harness check OK, monitor a digital voltmeter connected between VCM terminal C3 pin 9 and C4 pin 18 while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change. This may help to isolate the location of the malfunction.
An intermittent may be caused by any of the following conditions:
?€¢
A poor connection

?€¢
Rubbed through wire insulation

?€¢
A broken wire inside the insulation
Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
If a repair is necessary, refer to Wiring Repairs or Connector Repairs in Wiring Systems.

I have an error code of 53 on my 93 suburban. checking the voltage at the battery while running is 14.4 volts same voltage at the pcm checking and fixing every little possible thing related has not helped....


The 14.4 is high but not unusually so. The code may have been produced by glitch or a failing regulator or a corroded connector. That higher voltage shouldn't remain that high once the battery is charged. A charged battery should have very close to 12.6 ( I have often measured 12.65) volts with no load and no charging current.

92 suburban 454 v8 failed smog .


First I suggest that you have a code check done Most large parts outlets will do this for free.Control module problems will usually set a code. Just offhand, I'd check the egr valve to make sure the valve is clean and properly opening/closing. If the inspection readings were close but not perfect, sometimes "cheating" a bit by adding 2-3 oz of acetone per 10 gal. of fuel will clean it up a bit. It will not harm the system in that concetration,and will also clean the injector.

Check fuel pressure, and regulator. A leaking regulator gives a warm engine more fuel [ it does not like it] a cold motor does. same as a flooded motor. Good luck
