Top 10 1995 Chevrolet Camaro Questions & Answers

There is a computer chip on your ignition key that reads as you start it. Push the button on your ignition switch and it will come apart and you will find two little wires with a conector without them conected your secerity light will flash and will not start I lost my chip and hope someone can tell me how I can bypass it.

I had the same problem, thinking it was bad gas, or bad wires, or even a clogged fuel filter, had the engine checked out by a reputable gear head. A head bolt broke, then a intake lobe from cylinder #4 spun round thus causing your car to constantly backfire, also check to see if your head gaskets aren't blown (water-n-oil), all these were found once the engine was disassembled. Good luck trying to find a good used 3.4

If you look on the low pressure side of the AC system you will see a plug that is incorporated in to the line. It will have two wires leading to it. Remove the plastic clip that attaches the two wires to the sensor and use a short piece of wire to connect the two terminals in side the plug by putting the ends into the cap. This will bypass the low pressure sensor and allow the AC clutch to engage and begin to cycle again. Remember this low pressure switch is there for a reason. If you don't add more r-134 to the system and allow the AC compressor to cycle you will destroy the compressor. You need to charge the system when you bypass the low pressure switch and get the system up to full charge status and reconnect the switch.

cant bypass if u want to get rid of it need to replace ignition system with a non security chip system--including computer reprogram

This is most likely a leak from your rear main seal. It happens and can be a pain to replace if you're a DYI kinda person without the nec. equipment.

1. Raise and safely support the vehicle with jackstands.
   
2. Remove the transmission.
   
3. If equipped with a manual transmission, remove the clutch and pressure plate.
   
4. Remove the flywheel assembly.
   
5. Using a suitable prytool, carefully pry the old seal out.
   

6. Inspect the crankshaft for nicks or burrs, correct as required.
Crankshaft rear main seal - 5.7L engine

To install:

1. Clean the area and coat the seal with engine oil. Install the seal onto tool J-34686 for 3.4L engines, J 41349 for 3.8L engines or J 35621 for 5.7L engines.
   
2. Install the tool (with the seal mounted to it) onto the rear of the crankshaft. Tighten the screws snugly to be sure the seal will be installed squarely over the crankshaft.

1. Tighten the wing nut on the installation tool until it bottoms out.
   
2. Remove the tool from the crankshaft or rear oil seal housing, as applicable.

1. Install the flywheel.
   
2. If equipped with a manual transmission, install the clutch and pressure plate.
   
3. Install the transmission.
   
4. Check the fluid levels, start the engine and check for leaks.
   

yellow is power . red is ignition or acc. black is ground. front speakers : left positive tan, left - grey , right - light green , right + dark green , rear speaker : left - yellow , left + brown , right - light blue , right + dark blue . this is for the fatory wire color code if u need the actual wire color code for cd player it is . white is front left , grey is front right , green is rear left , purple is rear right. solid colors are positive and wires with the colors listed with black stripes is for the negative

Hi.

To start you should check if any error code is stored in the car computer (ECM).
Even if this car has a 16 Pin OBDII connectors, the codes should still be OBDI. Late 1995 Chevys are using OBDII.
Most code reader in commerce read OBDII codes only (introduced in 1995). Since a compatible code reader may be expensive and difficult to find, better having the code reading at a local dealer. The operation is done for a small fee.

If there are no codes, then follow the hints below. I will try to list the most common reasons for car not starting at random.

1 - AIT Sensor: The IAT sensor is used to determine air temperature. When the IAT sensor is faulty the car will have troubles starting with cold, and sometimes hot engine. The Intake Air Temperature sensor is located in the air hose going from the air filter to the throttle body assembly. Here a diagram:



2 - Fuel tank cap: The fuel tank cap must allow air out of the tank. If the fuel tank cap does not allow ventilation you experience starting problem.
Testing is done starting the car with fuel tank open.

3-Vacuum leaks: The vacuum system contributes to exhaust gas recirculation. A vacuum leak may give troubles particularly when idling, when starting , or when the engine is cold. This are the situations where recirculated gas make a bigger difference.
Vacuum leaks are detected using an hand tool gauge in the middle of vacuum lines, and heating the vacuum hoses with a blow torch at the same time.

4-Blockage in fuel lines and fuel pump problems: this will also affect driving, but better testing it. a small blockage may only give troubles when the engine is cold. The fuel pressure is tested using the same gauge that measures pressure on the vacuum system.

Here the tool to read vacuum and fuel pressure:Vacuum/Pressure Gauge and Fuel Pump Tester Mityvac 5511.

Water Pump - REMOVAL & INSTALLATION
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

under hood near fuses and other relays

You didn't state which one you were looking for, so here's location of both. The 3X (low resolution) crank sensor is on right side of cylinder block forward of starter solenoid----The 24X (high resolution) crank sensor is at crankshaft pulley.
