as it says... that's why I gave you a picture of the original reference of my old distributor, TD86U

Brand New Acura & Honda Ignition Distributor

Honda/Acura OEM Ref. # TD81U & TD84U & TD86U & TD87U

DOHC VTEC ONLY

Complete with Distributor, Cap, Coil and Rotor

In the ebay comment box during my purchase, I re-insisted for having the right equivalent.

On the package I received from them it was noted TD81U, but the distributor worked OK, I just changed the wire attachment point, but that's a minor detail honestly.

Honda is quite known for having multiple references for one similar piece, so don't worry about that.

nothing :(

new coil, new ignition module and not even close to igniting

main relay do usual click, sparks give strong spark, coil, modul and sparks wires are wired by the book, injectors recieve electrical signal during engine starting, they are spraying fuel in the combustion chamber.... bot not even cough from the engine

can be engine timing, ecu (which one was serviced once because of bad idle), some sensor (theres no ECL on dash)...?

problem solved

bad fuel pressure was cause of everything

mechanic replaced fuel pump, fuel filter, fpr, spark plugs, and made full injector service
