Then stop the engine and have it inspected by a professional.
engine have spark and fuel pressure and still will not start
To change the fuel injectors on a GMC Envoy, start by disconnecting the negative battery cable and relieving the fuel system pressure. Remove the intake manifold or any components obstructing access to the fuel rail. Disconnect the fuel rail from the injectors, then carefully remove the old injectors and replace them with new ones, ensuring proper alignment and sealing. Reassemble the components, reconnect the battery, and start the engine to check for leaks.
Check for proper fuel pressure in the 1997 Talon. The engine appears to be starving for fuel and only has enough pressure to start.
To recharge the air conditioner on a 2002 GMC Envoy, first ensure the vehicle is off and locate the low-pressure service port, typically found on the larger refrigerant line. Attach a refrigerant can with a gauge to this port and start the engine with the AC on max. Follow the instructions on the refrigerant can to add the refrigerant, monitoring the pressure gauge to avoid overcharging. Once the desired level is reached, remove the can and replace the service port cap.
Start error means that the "chipped" key message is not getting to the proper computers. You need a scan tool to check codes in the engine, skim, cluster, etc.
Just start the engine.
an oil light is designed to come on when there is NO oil pressure or LITTLE oil pressure. that said, when your oil light is on before you start your engine there is NO oil pressure to turn it off until you start the engine.
My 2002 GMC Envoy won't start,no lights come on when trying to jump start the battery. And my key won't remove from the ignition. What's should i do?
Engines need higher fuel pressure to start than they do to run.
For most vehicles, the fuel pump only turns on briefly when you try to start the engine. If the engine doesn't start, the pump turns off. You need to test the fuel pressure with the engine running.
If the engine is running, you will destroy the starter and possibly the flywheel/pressure plate.
A couple things could be wrong...... first thing you always want to try is another key, (if you have one) then if the car starts and no error message you know you have a bad key. if you still have a no start and error message it might be the transponder coil located on the ignition switch. could also be a bad imobilizer. Question.....does the engine start and then die right away? Or does the engine not start at all? a bad transponder coil will usually cause the start then die complaint. good luck!
