Timing chain setting for 89 Firebird

TDC related to piston one and should be as such.

Please tell me you didn't start a timing chain replacement job without know ahead of time how to set the timing marks.

If the timing chain fails, the engine will not have compression.
A faulty crank sensor should set a trouble code in the computer.

Hello smileynv: My name is Roger and I will answer for you.The 1988 Pontiac Firebird had a 2.8 v-6 engine. The timing set at 10 degrees in drive. The 1989 pontiac Firebird has both the 2.8 and a 3.8 engine.The 3.8 engine a DIS (direct ignition system) Had no distributor. The timing was preset and controlled by the computer system. There was no way to adjust the timing. Please rate the answer. This way I know it was useful. Should you need further help please just ask. Thank You for using Fix Ya. Roger

BACK IN 1989 BEFORE YOU TIME THE CAR YOU HAD TO PUT IN BYPASS MODE THE ELECTRONIC SPARK TIMING.FIRST THING YOU DO IS WITH ENGINE OFF.CONNECT THE PICK UP LEAD OF AN INDUCTIVE TIMING LIGHT TO THE NUMBER 1 SPARK PLUG WIRE CONNECT TIMING LIGHT CABLES TO THE BATTERY POST.TIMING LIGHT CABLES ARE COLOR CODES RED CABLE FOR BATTERY POSITIVE BLACK CABLE BATTERY NEGATIVE CABLE.RUN ENGINE UNTIL ITS OPERATING TEMPERATURE.LOOK UNDER HOOD ON RADIATOR TOP SUPPORT FOR TIMING SPECS.YOU WILL NEED A TACH METER FOR SET IDLE SPEED. WHEN YOU ADJUST TIMING.OKAY WHEN ENGINE GET WARM ENOUGH.BESURE HOOK UP TACH METER WHEN YOU HOOK UP TIMING LIGHT.WHILE ENGINE RUNNING GROUND THE DIAGNOSTIC TERMINAL UNDER THE DASH. ON THE ALDL CONNECTOR GROUND TERMINALS. B AND A. THIS PUT SPARK TIMING IN BYPASS MODE.CHECK TIMING BY AIMING THE TIME LIGHT AT THE TIMING MARK ON THE HARMONIC BALANCER.IF ENGINE TIMING REQUIRES ADJUSTMENT.LOOSEN DISTRIBUTOR HOLD DOWN BOLT AND ROTATE THE DISTRIBUTOR SLOWLY IN EITHER DIRECTION TO ADVANCE OR ****** THE ENGINE TIMING.WARNING BECAREFUL WATCH COOLANT FAN BLADE AND DRIVE BELT WHEN USING TIMING LIGHT.DONT WEAR LONG JEWELRY OR BRACLETS.ROLL UP LONG SLEEVES SHIRT OR COVERALS.IF YOU HAVE LONG HAIR TIE IT UP.ALL THIS FOR YOUR SAFETY. IF THIS DONT HELP YOU CAN BUY A HAYNES OR CHILTON REPAIR MANUALS. YOU CAN GO TO ANY AUTO PARTS STORE BUY ONE.

correct on both your guesses. check your firing order making sure that #1 is in the correct place on the cap

the sound of what you explained is more that the timing is 180 degrees out... that would explain the no power on the road.... it would also allow the timing marks to line up.... hope this helps

buy manual, it is probably electronic not adjustable

1-8-3-4-6-5-7-2. This stands true for gm '79 v-8's
