IAC / Swap problems
tried to search for the answer, no luck! everyone try this one out!
setup:
99 dx hatch w/ b18c1 (wired with 99 Si hardness for plug and play!)
stock Si ecu and / or obd1 P72 w/ Hondata
this is my situation:
after a long delay for parts, i finally finished my motor build. install was no sweat. Using a 99Si hardness, everything was p&p but the IAT sensor. With the use of a stock Si ecu and everything ready for start-up (ie. fluids), i went for it! What did i get? NOTHING!! KOEO there was no fuel pump action but a funny noise from the Main Relay and IAC area. So thinking that it might be the Main Relay, i replaced it and tried it again. Same thing, nothing! This time I unhooked the IAC valve, because it was making funny noises, with the KOEO. After doing that, the fuel pumped kicked on and it primed the system! so this is the problem that I'm having, with the IAC valve plugged in and KOEO, i get nothing! With the IAC valve unplugged and KOEO, the fuel pump kicks on!
does anybody know why this is happening? or what to do to fix this?
p.s. -
i also had a spare IACV and tried that one too, same problem!!
same thing happens when i use the P72!
Also have tried 3 different main relays to see if thats the problem, no go!
Checked to see if there was a short/open on the blu/blk wire side of the IACV,
checked out ok!
anyone?
