I have a 1983 Honda Accord Auto which will not start. Have checked the ignition coil and spark plugs, and there is a spark but it is weak. Have tried with a new ignition coil and the same problem exists. The car will crank but will not fire.

replace the ignitor

Someone needs to check for voltage at the coil and the distributor.
The pickup coil in the distributor tells the coil when to fire.
If you are getting spark at the coil tower but not at the plugs, check the cap and rotor.

MAKE SURE SPARK PLUGS AND WIRES IN GOOD CONDITION, REPLACE DISTRIBUTOR CAP AND ROTOR,CHECK FOR SPARK AT SPARK PLUGS,IF YOU DONT SEE SPARK CHECK TO SEE IF POWER GOING TO COIL IF NOT CHECK IGNITION FUSE.IF FUSE OKAY AND POWER GOING TO IGNITION COIL,COIL FAULTY OR IGNITER UNIT FAULTY. CHECK FOR FUEL PRESSURE MAKE SURE FUEL FILTER BEEN CHANGED.FUEL PRESSURE SHOULD BE 40 PSI. IF YOU GETTING SPARK AND FUEL. YOUR IGNITION TIMING OFF OR VALVE TIMING OFF DUE TO A WORN TIMING BELT.

Either the spark plug is faulty or the coil pack is faulty.The spark plugs get power to spark from coil packs.

If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).

But if the coil has voltage, then problem may be a bad high voltage output wire from the coil to spark plugs or hairline cracks in the coil output tower.------Getting this all possibilities checked will point towards the exact faulty part which is to be replaced.----------This should help.Thanks.Helpmech.

no my friend the rebuilt distributer is find, the ignition coil is on the engine block, that is what send sparks to the plugs, may be that is weak

very simple system and the only thing left is the coil and power to the coil. have you check the main 65 amp fuse and then the other fuses? i would make sure there is power getting to it and if so change the coil.

good luck

Could be the ignition coil or ignition module. Also check the ignition fuse.

sounds to me like a bad rotor, pop the dist. cap off and check the contacts inside

follow tithe wires from the spark plugs these have to go to the inginition coil (not sure if this car has one per plug or one ber the whole motor, but the all have to go to a coil even if it is shared)
