2004 gmc envoy slt service engine light is on and it vibrates when sitting still almost like shaking could my fuel injection be clogged

correction this is a 4.2L not a 2.4L
Do a 2004 GMC Envoy Slt 2.4L have a ignition module?
The engine will turn but want start no spark at the spark plugs boot what could be the cause no spark? AmanStino 3 USB ports Car charger with 1 Type port AmanStino

Do you have any codes or an engine light on, in your dash board ? Have you checked for spark at your plugs ? There are many things that could cause a vehicle to not start. Bad camshaft/crankshaft sensors. Poor ground wiring. Defective spark plugs or wires/coils.

run the fault codes as there should be a fault recorded when the light came on

I think what you might have is called dieseling on shut off. Newer engines run much hotter than older vehicles and require a fuel shut off solenoid close to the engine. If this solenoid goes bad, on vehicle shut off, excess fuel is still being fed to the engine. Even though there is no spark because the key is off, the engine is hot enough to ignite the fuel causing the shake and shudder. I'm not 100% sure of this but thats what it sounds like. If the solenoid is working properly and shuts off the fuel line like it should there is no excessive fuel to ignite. Thus no shake or shudder.

More than likely the stepper motors that drive the gauges are going bad, this a common problem on these instrument clusters. There are several repair services listed on E-bay who repair clusters, if you are willing and capable of removing it from the vehicle.

with the injection the gaz filter is in the gaz tang with the gaz pump.

disconnect batt. for 30 min. then reconnect,if no problem exist the lights will go away

its gone into limp mode.you need a service and the coeds cleared

You need to check the fuel injection system, throttle body, sensors, check harness for ground. Best solution is to have your engine scanned using Tech 2 scanner. The mechanic will advice you based on the scan code. Whenever the "service engine soon " light the computer system logs the error code. You can retrieve this error code using a scanner.
