F20B swapped '99

[F20B6THGEN]

my accord recently started takeing its time wanting to start whether it be cold or hot out, i have put 3 main relays in it, still it takes a few minutes to kick on the main relay/ fuel pump relay, i have checked all my grounds and input leads in the plug to the main relay... im running out of ideas, it is tuned on chrome, i have no idea what ecu is in it... any other questions you may have to help me figure out this problem please ask, i need to try and resolve this, cause some days it wont start at all....

Replace the plugs just in case. What gas are you running. You know you have to run premium in that puppy right?

i did the plugs, and im running 93 in it, but one other thing is, that it will not start till the check engine light goes off

Weird... sounds like some wrong wiring somewhere in the swap. Mine is hard to start only after I put gas in it for some reason...

idk, ive been thru all my grounds and stuff, and tried the ignition switch, but it was a fail... the ignition switch is good, and i remade all my grounds....

still need help if n e one has n e ideas..... please help cause the import garage i dropped it off to this morning couldnt figure n e thing out, they said they had no way of testing it, but their guess on what it could be was the ignition switch(which i have already tried), and the ecu, but i dont wanna spend a whole lot on an ecu if that wont fix my problem, so please any suggestions you may have, feel free to give it a whirl.... thanks

My car did the same thing and I replaced all the same stuff you did. Finally gave up and found a race mechanic who knew how to fix all the wiring. I was running a bypass harness. I would seriously check which ECU you are running and if it is compatible with your swap.

My car started to slowly die and it was unexplainable random... hot or cold. You may need to reflash and reprogram your ECU. That's what I had to do with my CL type S.

Good luck.

i am working with a guy i just met, and getting a P28 ecu and haveing him tune the chip for a base tune, so maybe i will go ahead and try it man, cause i have tried everything, and i dont have a race mechanic any where close by... so i guess its gonna have to be trying an ecu....

 

[F20B6THGEN]

and i do appreciate that info, cause i was seriously debating on it, so now i think im gonna go ahead and try it.....
