Unlikely
code p 2101 is throttle actuator problem and code p1516 intake manifold air control solenoid
no spark can be cam/crank position sensor, immobilizer , ignition control module or ECM problem

2004 GMC Envoy SLT 4.2L the engine will crank but want start why?


P1516 = Throttle Actuator Position Performance
P2101 = Throttle Actuator "A" Control Motor Circuit Range/Performance

Both of these codes indicate a problem with your throttle position actuator system. I'm not sure how GMC/Chevy treat this, it's possible that if the PCM/ECM will not allow the engine to start if the throttle actuator is not working properly (it may cause the engine to accelerate rapidly when running). You could try replacing the throttle actuator, but that may not solve the problem if it's a wiring issue. Best to have it checked out by a qualified mechanic.
