Question edited for clarity and spelling, it is a 'Jinlun', not 'lum'.
Question moved for Cars and Trucks to maker category.
Made in China and generally regarded as disposable, they are $600 new. The pulse unit will be on one end of the crankshaft. Check the parts suppliers for a parts diagram, or here
A code P0305 may mean that one or more of the following has happened: Faulty spark plug or wire Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector Burned exhaust valve Faulty catalytic converter(s) Running out of fuel Poor compression Defective computer
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hi,
I would be looking around for any other munching by varmits. Your ecm is under the hood. Critters could have taken out more wiring. look under battery area and ecm area for starters.
The spark gets power to spark from coil packs.If the connection between coil pack to spark plug is weak or loose then it will not fire.But if the coil pack as well as the connection between coil pack to spark plugs checked ok then its faulty or dirty spark plugs.Clean the spark plugs with the carb cleaner liquid and let it completely dry.Then check.Also check the voltage between coil pack to spark plugs.If both checked out ok then the other possibility can be weak crank shaft sensor.
Thanks.Helpmech.
Not much info Smitty but if that weak spark is constant (ie:pulsing ) i would guess that the trigger coil is ok.I'd make a check on your ignition coil earths then do a couple of continuity tests on your coil primary and secondary , orange terminal to ground,orange terminal to ht lead ,if they check out ok according to service manual specs then i'd run continuity test on the source coil.....Hope this is helpful in someway ...Smittycat.......from Flabbycat
