Cam position sensor tells computer when to synchronize injector pulse. Have you checked for trouble codes?
Check injector fuse. Injectors should have constant voltage supplied when key is on.
You didn't give year and model. Injectors are pulsed when the engine computer internally grounds an injector. You may need to check injector circuit.

1995pontiac,firebird6cyl,sputters at 2000rpm


When you say "sputters at 2000 rpm" , are you referring to ANY time the engine is at 2000 rpm - meaning in Park, when you are just goosing the throttle, or in gear when you are accelerating, or at highway speed in high gear? If you are experiencing a "shuddering" in the engine at certain speeds/rpms - especially if these are speeds you regularly cruise at (long commutes at steady speeds), the problem could be in the Throttle Position Sensor (TPS). They have a tendency to wear unevenly if you drive a certain steady speeds. Eventually, the problem would progress to an engine code, but it may occur without setting the check engine light.

Why can't I get spart. Don't have injector pulse.


Loss of injection pulses usually means a loss of an engine timing signal or even the security pack preventing the vehicle from starting.
You need to check all the timing signals, crank angle sensors, cam angle sensors etc and ensure that any security is disabled or turned off.
Check for spark, if you have spark but not injection pulses, then its a timing signal issue. If you dont have spark or injection pulses, also check the ECU (the cars computer) although I do not know of any issues with this make and model.

No injecter pulse new engine


Crankshaft position sensor is the likely culprit. Check and verify connection and if good, replace the CKP.

My car is 1995PONTIAC Firebird 3.4L V6, burning oil is now very serious, to the number fluctuated greatly speed up the sound of the engine can not VIN: 2G2FS22SXS2215261


your valves are probably sticking many firebirds have had problems with the heads on the vehicles.. example my 91 firebird burned oil for over a year and a half before a head gasket blew out and consequently cracked one of the heads.. but now im jus down to getting past old vats security systems.. the heads on the vehicle are expensive, so take care of them, replacing the valves may be kinda expensive but is cheaper than hole heads.. also check for any gasket leaks or oil near the valve covers, could be a head gasket.. head, valve cover gasket, valve cover, oil rings a generalized area of where the oil is coming from would be helpful

Hi you should check the alternator, when the charging sistem is defective ,the idle goes up to keep the engine runing ,the battery is not getting charge so eventualy it will go dead.
