You need fuel, compression and spark to run, you are missing one of those.
seems that the timing is still incorrect. the distributor may be worn and causing this.problem may also be the points, a crack in the distributer cap,
i need the ignition timing for 88 chevy 5.7 ... 350 motor i had the truck on 4 but still bad don t run good
You could put a vacuum gage on the engine and time it for peak vacuum. A timing light is still better.
To reset the check engine light unplug the battery for 30 minutes. If the issues still persists the light will still light up when reattached.
If you have already replaced the belt and the light is still on you will need to remove the lower and upper dash panels and then remove the instrument cluster which holds your speedometer and other devices. The reset button for the timing belt light is behind the cluster.
maybe check for a worn CAM LOB.
with a timing light, assuming this is an older engine that still uses a distributor.
either your timing is off or your valves still need adjustment
unhook the positive on the battery for 5 min. This should reset your check engine light if it doesnt then you still have issues.
Chevy does not have a reset switch. If you installed a fuel pump and it still won't work, Then you need to check the wiring harness at the pump where it plugs into the top of the tank. Chevy had a problem with the wire connector at that point.If that checks out okay, then check the fuel pump relay and fuse.
Disconnect the battery for 15 minutes. If it is still on then you must see a GM dealership.
I'm not sure if you are asking about engine timing or the radio clock. Please resubmit your question and if I'm still on here, I'll try to answer it for you.
