Question about 1991 Peugeot 405
I would suggest taking out ALL the plugs. The engine will turn over much faster and not drain the battery. You may find that the fuel in the engine has become diluted with water. This turning over without plugs will do a couple of things: a)free up and lubricate everything.
b) give the fuel pump the greatest chance of getting fuel through to the cylinders, c) purge some stale fuel out of the engine. You should be able to smell petrol vapour once it's coming through, albeit feintly.
c)Give you chance to check the spark on each plug.
NOTE THE LOCATION OF EACH PLUG LEAD! If these get swapped round, it will never start until they are corrected!

Pull out a spark plug and plug it in to the spark plug wire, then use a jumper wire to ground the hooked part of the plug to ground have an assistant crank over the engine while you observe the spark plug for a blue or purple spark if no spark is present or the spark is yellow or white there is an ignition problem and that will be the issue to be addressed.
