i built a RHD integra with a B20 vtec and im having problems with the spark. i got fuel, i tryed several working distributors, i tryed the ecu swap, checked all fuses, checked all grounds, check continutiy from the wires going to dis to the ecu. still nothing. is the jdm computer different from the usdm? WTF do you think it is?

 

Ok here is the 411 on this no spark problem.

We searched the archives already and have found nothing.

There is a good reason for this.

The front end of this DC is JDM and the rear is USDM glued together(kidding).

The engine harness is an uncut JDM GS-R one. The main plugs are hooked up like the injectors, dizzy, map & oil pressure. Everything else is still unplugged for now.

We checked wires from the dizzy to the ecu and its good. The ECU plugs are Ok,(meaning there were like 2/3 wires that were cut but it was already corrected). Since we do not have a JDM Helms manual we do not know if its the same as the US models.

The dizzy and ECU were donated from another working DC so it cannot be that cause it worked.

The car has fuel, main relay is good(also exchanged just to be sure), the car would just keeps cranking over but no spark. we just cannot figure it out.

Does anyone have an JDM Helms manual or if possible an on-line website that has that so I can look it up???

This is some mind boggling **** man. It's like trying to understand women, well sort-of.

Anyone care to help......please.

does it crank or not even that?????

 

Edited: yes it cranks over fine.

 

u check the dist

as I had this problem

and when tune up was done the rotor was turn 180 degress wrong

so it was firing from cyclinder number 4 instead of #1


just something I could think to try
