forevermemorable Posted August 25, 2013 Share Posted August 25, 2013 (edited) My 1996 Honda Odyssey is working perfectly except for a check engine light (which Pep Boys diagnosed it for free and told me upstream oxygen sensor).So, I purchased a brand new (non refurb.) upstream oxygen sensor and install it (I forgot to disconnect the negative battery). I go to start the car and the car will not start (meaning it won't even crank)! There is plenty of battery juice and all the lights come on in the dash (except for the usual check engine light), but the car will NOT turn over and even attempt to start. I tried to give it a jump, but to no avail. The battery is perfectly fine...only 1 month old! I checked "ALL" fuses under the hood and in the car and they check out perfectly. I even replaced some of the fuses with new ones, just to make sure. When I turn the key, the car doesn't even start at all or attempt to start. My first guess is something electrical. Ever time I turn the key, I hear the fuel pump trying to work, but the car will not start. Do I have to reset the ECU in order for the car to start? I currently have the negative and positive battery connections disconnected and I am waiting awhile for that route.I have also reinstalled the previous oxygen sensor that was on the car, but that did NOT work either. Lastly, in the past few months, I replaced fuel filter, spark plugs, distributor cap & rotor, spark plug wires, air filter, oil filter, PVC valve, and two new oxygen sensors! There is half a tank of gas and plenty of oil and all other fluids. Edited August 25, 2013 by forevermemorable Quote Link to comment Share on other sites More sharing options...
Humphries Posted August 26, 2013 Share Posted August 26, 2013 tap starter. might be stuck on a flat spot. o2 sensor would have nothing to do with the starting/charging system. you should not work on your own cars. you seem to love to throw parts at it.

forevermemorable Posted August 26, 2013 Author Share Posted August 26, 2013 you should not work on your own cars. you seem to love to throw parts at it. Let me rephrase, I purchased the car 3 years ago and all the above mentioned items were time to be replaced. What I am saying by listing all of those items I replaced, is that it could not be anything related to those, since they are brand new. I love working on my cars (its affordable than $75 - $150 an hour by the mechanic fees here in California). I am just not the greatest when it come to diagnosing cars, nor do I have the expensive tools like shops have. Quote Link to comment Share on other sites More sharing options...
forevermemorable Posted August 27, 2013 Author Share Posted August 27, 2013 After watching a video about tapping on the starter and your post to suggest starter, I was able to get the car started. Quote Link to comment Share on other sites More sharing options...
