the lost now glove box user guide on all cars cover all that. so if lost get it google finds them all so do so some are even free. if you googled. 1993 is paper only guide. one is under hood one is under dash see page 306, here, the photos are crude scans of 30 year old old booklet so be happy some poor dude scanned it. it is all there and can be downloaded free 100% free. and best place of all. https://www.manualslib.com/manual/231732/Gmc-1993-Safari.html?page=306#manual USA car one fuse box is just to the left of steering column at toes has huge black cover over it ,day1 new car. that simply pulls off and the fuse panels is there. under dash left USA LHD CARS

I know EXACTLY what your talking about... its the starter.. my truck did that, but i never fixed it.. i would always just turn the key on and off real quick and after 5-20 clicks it would start



TING!

go to starter check the red wire with test light make sure you have 12 volts and then check the purple wire to the solenoid and hve someone turn key to crank should have power at that wire when in crank if not check the relay and theres a 10ap crank fuse

Common symptoms for failure:

• Check Engine light is on.
• Car is getting poor gas mileage.
• Emission test fails.
• The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine.
• Starting with a few vehicles in 1994 and 1995, and all 1996 and newer vehicles, the number of oxygen sensors per engine has doubled. A second oxygen sensor is now used downstream of the catalytic converter to monitor converter operating efficiency. On V6 or V8 engines with dual exhausts, this means up to four O2 sensors (one for each cylinder bank and one after each converter) may be used.
• http://www.aa1car.com/library/o2sensor.htm
• This site gives generic info, with a list of: Most O2 sensor problems will cause the OBD II system to set one or more diagnostic trouble codes (DTCs) and turn on the Check Engine light. These are the OBD codes associated with O2 sensor faults: 39 listed You need to test and get the code that in turn tells which sensor.
• The code displayed on your scan tool will indicate the type of fault, and identify one of the oxygen sensors by its position in the exhaust system. The oxygen sensor's location will be identified by position (sensor 1, sensor 2 or sensor 3), and by cylinder bank (bank 1 or bank 2). Most late model engines have multiple oxygen sensors, so which one is sensor 1, 2 or 3, and how do you know which cylinder bank is 1 or 2? On straight four and six cylinder engines, there is only one bank of cylinders. So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2. On V6 and V8 engines, Sensor 1 will always be on the SAME side as the Number ONE cylinder in the engine's firing order. On GM and Chrysler V6 and V8 engines, cylinder number one is typically the LEFT front cylinder on the driver's side in a rear-wheel drive car or truck. On a GM front-wheel drive car or minivan with a transverse (sideways) mounted engine, the number one cylinder is on the front side of the engine (closest to the radiator) on the right (passenger side) of the engine.

Found this info, hope it's correct. 4.3L engine.

Usually it's the oil cooler lines.

If I see your problem correctly. The engine starts but won't run but it runs with a remote control. If this is your problem then I will check with a test light at the connector under the dash on the column steering if there is + on the run ignition switch position. Meaning 1. Unplug anything to make the engine to won't starts the engine(security) 2. Turn the ignition switch to start or run back and forth then backprobe terminals at the column steering to see if you have + switching between the on position and the run position. if not find out the IGNITION SWITCH assembly or WIRES problems or terminals (no contact) at the connector.(Not the ignition solenoid like you say) Hope it helps.

you have a plugged radiator or heater line to back heater unit not allowing coolant to flow

short in the wire after the fuse and before the ECM unit

Anti-theft light lit on the instrument cluster (SECURITY) . The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key turns the lock cylinder. The cylinder rotation produces an analog voltage code in the Passlock™ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a class 2 message is sent from the BCM to the powertrain control module (PCM)/vehicle control module (VCM). The message enables the fuel injectors.

Could be heating fitting because is old.

there will be fault codes if the correct scanner is used there is a protocol required for several manufacturers ECM units which require a correct protocol in the scanner before the codes are revealed

All 12V systems will have the voltage regulated to 13.5-14.5 Volts output from the alternator while running. If you need further help, reach me via phone at https://www.6ya.com/expert/steven_a67ead41eb5fc62a

Take it to a qualified repair shop .

Doesn't have a mass air flow sensor , uses a Manifold Absolute Pressure Sensor (MAP Sensor) Speed density control Symptoms of Bad or Failing Manifold Absolute Pressure Sensor MAP Sensor... http://www.xcceleration.com/sd-vs-maf.htm

Maker sure no fuel pressure on the system before you take any fuel lines loose. Usually after the vehicle sits over night w/o the key being cycled, not much pressure, but, you still need to be aware. The filter I looked at had threaded fittings on both ends, so use a couple of wrenches, take it loose slowly and try to wiggle line and or old fuel filter, just in case of pressure. Use a catch pan, gas will probably run out of lines, if you think too much gas runs out, plug the lines till you get ready to go back with new filter, just remember to remove plugs. If you use a drop lite, don't place it where gas can't get on it.

If you hazard flasher work than replace signal switch after you check fuses
