Door jamb serial number shows EARLY special...looks like 1953 Kaiser Manhattan in interior and uses a 1953 Kaiser body (one piece rear window rather than 3 piece like on the 1954 Manhattan) and has 1954 front sheet metal and taillights.
Check list for starting...
1. With battery hooked up properly (see Jim Betts' comments) and headlight switch pulled out, do you have lights? If so, turn off lights & go to #2
2. Turn ignition key. Do the gages on the instrument panel register? If so, turn off key and go to #3.
3. Verify that engine has not siezed or otherwise turns over. If ok there, go to #4
4. With condition of battery, ignition switch and engine turns, turn key to start...does the starter crank over? Does it go "click"? If it goes click with no other action, clean the battery cables, battery post, tighten cables down and try it again. If it continues to click only and cables are old, replace cables and ground strap. and try to start again.
5. If nothing happens, repeat steps 1 and 2. If ok there, check fuses and circuit breaker for replacement or reset and then try again to start.
6. We are looking at this point ONLY for engine to turn over on the starter, not fire up.
7. If engine turns over, Disconnect ignition coil wire from distributor and tap the contact in the wire end on the block while turning the engine over. You should get a noticable spark off the coil. If you do not, check wiring of coil to battery and ground, also check coil to distributor wire.
8. If you have spark, re-connect the coil wire to distributor and dump a bit of fresh gas into the carb. Turn the key. Engine may attempt to start and/or sputter a bit as fresh gas is burned up. If nothing happens, pull plug wires at plug and do the kind of test as in #7, to see if all plug wires are sparking. General practice would be to pull the plugs and replace them with AC 45 or equivilent heat range from another brand plug.
9. If you do not see a spark at each plug, you may want to replace the plug wires on general principles. Also, take off the cap and turn the engine over. Does the distributor shaft turn the rotor and do the points open and close as the distributor cam rotates. If the shaft does not turn, at least part of the problem is that the drive gears inside the engine are not right. If shaft turns, replace rotor and contacts then repeat check, adjusting new contacts as needed. Also, check the little cotton-wrapped piece of wire in the distributor. This can break inside the insulation...it can look OK outside but not work internally. Also check vacuum line from distributor to carb to see if you get suction.
Check these things out and see if you can get it at least to sputter. You may have to remove the gas tank and have it cleaned and checked, blow out the fuel line, clean it and blow it out a couple more times, rebuild/replace the fuel pump and see if it will run on its own.
