90 Honda Accord help?

Question

I have a 1990 Honda accord that cranks but wont start the blink code on the ecm i believe is 41 can anyone tell me what the obd1 codes are i can not take the car anywhere so please help thanks

Answer 1

code 41 is for a failure of the heater circuit for the heated oxygen sensor.  that is not the reason for your car not starting.  the oxygen sensor heater is like the element in a toaster.  its function is to warm the sensor up to temperature faster because a cold oxygen sensor is inefficient.  

the no start problem with the 90-93 accords is usually because of a failed main relay.  the main relay controls the fuel pump and the pcm.  check to see if your fuel pump is running.  you can do that by taking the fuel cap off the gas tank then have one person turn the ignition key ON while the other person listens at the fuel filler tube to hear if the fuel pump is running.  the pump should run for at least 2 seconds when the key is turned ON (you don't have to crank the engine).  the pump running will sound like a buzzing noise then shut off.

if the fuel pump isnt running the problem is with the main relay.  the main relay is up under the left side of the dash roughly behind the coin tray.  the relay costs about $50 at a honda dealer.

you can also check to see if  you have spark.  if you don't have spark from the spark plugs when cranking you could have a bad ignition coil or it could be the main relay.

forget the blink code problem as that's not whats keeping the car from starting.  check for the fuel pump and for spark and you'll be on course to figuring out why the car won't start.  even money odds are on the main relay.

hope that helps

Answer 2

Stop cranking.  You are wasting the battery juice.  I do not know what 41 is..  Why not call Honda and ask them?  And if you do not trust them, try an autoparts store..like NAPA. the store clerks sometimes got some ideas on these things too.   The more answers you get from various sources the better your chances are that you can focus in on the right answer.(because 2 or more answered the same-other than "dunno")
