maybe check for a worn CAM LOB.
Timing chain jumped? distributor cap is cracked or igniition wire are mix up
electronic spark timing is your distributor.
If you have the 3.8L engine, ignition timing is controlled by the computer and cannot be altered without making changes to the computer. If you have the 3.1L engine, which has a distributor, you can set the timing as you would on any engine with a distributor.
Will engine run at all if the distributor is not wired correctly
rev the engine to about 2500 rpm's and turn the distributor until you find that sweet spot.
It is electronic controlled and requires an OBDII engine scanner to set the timing if it has a distributor. If it don't have 1 then there is NO adjustment for the timing. You did not give the engine size.
You will have to have an oBDII engine scanner and then go into the timing mode with scanner. You will then move the distributor by hand while watching scanner until it is in the specs. You can not use a timing light. The timing is controlled by the computer.If you did not have the distributor out of the engine are move it, Then there is no reason to set the timing. The computer will do it for you.
The timing is computer controlled and there is NO need to fool with the timing as long as you have not moved or touched the distributor. It requires an OBDII engine scanner to adjust the timing.
The timing is not ajustable on that engine. It is controlled by the computer. If you have not removed the distributor / That is if it's a V-6 engine then there's no reason to worry about are to full with the timing. If you have moved the distributor the you MUST have an engine scanner to put the timing back were it belongs. The V-8 engines don't have a distributor. A timing light is the thing of the pass. There no longer used.
Disconnect the plug going to the distributor that has two wores. Start the engine and set the timing to 0� (TDC). Stop the engine, reconnect the plug and the 'puter will handle the timing from there on.AnswerDisconnect the plug going to the distributor that has two wires.

You can't, it is not adjustable, The timing is controled by the computer and there is no reason to mess with the timing. Now if you Have had the distributor out and put it back in and the engine will run and it has no check engine light on then you got lucky. Now if the light is on then you will have to get an OBD2 engine scanner and then go into the timing mode and move the distributor until you get cam and crank in time and the check engine light will go off. Tighten distributor and the computer will do the rest.
The 1987 Chevy Celebrity has distributor less ignition. The timing is controlled by the engine control module and there is no provision for adjustment.
Turn engine over and observe is distributor is rotating
There is no adjustment on the timing, It is controled by the computer. If you did not have the distributor out then there is no reason to worry about the timing, Unless the check engine light is on and you had it scanned with a engine scanner and it said that the timing was off. You will then need to hook scanner up to engine and go into the timing mode and move the distributor until the light goes out. Then tighten dist. and the computer will do the rest.
To set the timing on a 1984 Chevy Celebrity with the V6 engine: 1. Disconnect the HEI connector so the engine will run in closed loop. 2. Start the engine and use an inductive timing light to check the timing. It should be at 100 before top dead center 3. If the timing is off loosen the clamp at the base of the distributor and turn the distributor so that the timing is set. 4. When you have set the timing tighten the clamp and verify that the timing did not change. If it stayed the same reconnect the HEI connector.
You can not use a timing light to set the timing on that year engine. The ignition timing is COMPUTER CONTROLLED. If you have not fooled with the distributor then there is no reason to adjust it. But if you have bother it then you will need an oBDII engine scanner to put the timing back to factory specs.
That requires an OBDII engine scanner. Can not use a timing light ( won't work )
timing does not need to be set on the 1.3l engine in model year 1999 as it is a distributor less igniton system all timing is done by the ecm
That requires an OBDII engine scanner to do that. The ignition timing is controlled by the computor. If you have not moved are removed the distributor then there's no reason to fool with the timing.
you turn the distributor and use a timing light
The engine will not run.
You must have an engine scanner to set the timing correctly.
with a timing light, assuming this is an older engine that still uses a distributor.
what is the ignition timing for a 1988 Chevy 454 engine
You can't, The timing is controlled by the computer it is not adjustable. If you had the distributor out of the engine, then the only thing you can do is put it back in with the rotor pointing to the #1 pistion on the compression stroke and then move it enough to get it running. Then you will need to get a OBD2 engine scanner and go into the timing mode and set the timing with the scanner to factory specs. If you did not have the distributor out and the check engine light is not on. Then you have no problem with the timing and no need to scan the engine, the computer will take care of the timing.
