    Honda bf225a wont start after new main relay instale.

    I can get a used one on ebay for 2 to 3 hundred. Think I will go this route. If I rig something up I will probably end up offshore stranded with some new problem. Will let u know when I get it replaced.

    ok I installed new relay this afternoon and have same problem. I did as you described, and pump runs when grounded at the light green wire. I checked and have continuity from light green wire at 6p connector to the plug at ecm. Does this eliminate the possibility for bad ground? If so sounds...

    Ok relay is already on its way back to supplier, and I should have a new one tomorrow or Thursday. If I have the same problem with new relay I think you are on the track that I am looking for.

    I have a Honda shop manual and have done the main relay check and had continuity and voltage at every connection in the test diagram. ( 4 pages of tests). Yes it appears one of them was a test from the #3 terminal of the 4p connector to the #19 terminal on the 26p connector and I did have...

    I think I have narrowed it down to the new main relay being faulty. No power to fuel pump plug. Wire from plug to relay is good. Can wire fuel pump to 12v and it runs fine, and can get engine to run while fuel pump is direct wired from 12v. I do not have continuity at the 2 prong plug on the...

    I flip flopped all 10 amp fuses in fuse box. I switch 1 with 5 and 2 with 3 so that I knew where they were originally if I had to put them back in original configuration. I also think it is in wiring, just looking for best possible common area to look after a main relay melt down.

    There are also 3 codes. #13 Baro sensor (there prior to problem) #21 vtec selenoid disconnected, short or open circuit, or faulty selenoid. (new since main relay failure) #23 knock sensor (there prior to problem)

    I fried relay Saturday, it was pretty clear what happened. Removed cover and all three pigtails and selenoid wires where melted together. Replaced main relay yesterday and now engine cranks but won't run. Do not here fuel pump running and have tried to ck voltage at fuel pump wire connector. I...
