I CALLED A DEALER TO GET A GOOD ANSWER. ONE OF THE MECHANICS WHO HAS DONE QUITE A FEW VENTURE TUNE-UPS. HE SAID THAT HIS BEST METHOD FOR HIM WAS TO REMOVE THE COIL PACK FOR ACCESS TO THE PLUGS. HE ALSO SAIDS THAT THERE MANUAL STATES THE BEST WAY IS TO ROTATE THE ENGINE FORWARD. BY DISCONNECTING TO DOGBONE MOUNTS ON THE FRONT OF THE ENGINE AND PULL THE ENGINE FORWARD. NOTE: VERY IMPORTANT POINT USE ONLY ORIGINAL EQUIPMENT PLUGS AND AND DO NOT REPLACE WIRES WITH CHEAP MADE WIRES. NOT DOING THESE TWO THINGS CAN CAUSE MISFIRE PROBLEMS AND OTHER POOR PERFORMANCE PROBLEMS

One reason a 1993 Chevy Lumina may turn over but not start could be the battery. It may also be the spark plugs.
On my 93 lumina you remove the top engine mounts from the motor,rotate the motor forward(set park brake & put in N)until you can put the bolt back thru the hole in the lower side of mount to hold engine back. On mine you can only do this on driver side
Freeze plugs in a 96 Lumina are located at several places on the engine block. They are designed to expand and burst in a freeze instead of the engine being damaged.
Spark plugs are a cheap and quick fix if one goes out. The cost to replace one on a 454 chevy engine however can differ depending in the spark plug brand.
you have to take the motor brackets that hook the motor to the front of the car and then roll the engine forward carefully to get to the back three plugs.
It is quite easy to install the 1992 Chevy Lumina brake light switch. The brake light switch simply plugs in and out.
Without an engine size we guess but if you can't see them then they're under the center plastic cover of the engine. Cover will have coils,wire boots, module & plugs under it.
