h22 turbo - Car won't start

[ripsta]

I’ve got my turbo Accord finished but have a possible wiring problem I could use the forums input to help address. It is a prelude motor with prelude wire motor harness plugged into Accord sub harness going to the ECU. I’m using S300 Hondata ECU for Reference. I’m attached a spreadsheet for the PIN outs to the ECU for the 3 cars to see what is different and needs to be changed…


We first installed the Accord ECU into the car and we had spark and fuel pressure but of course it wouldn’t fire the motor being that I have over double the injector size and we tried to lower fuel pressure also just to see if it would start but no go…. The S300 wouldn’t give the car fuel pressure when plugged in and a custom map for the motor loaded… We tried about 6 different maps to see if that was the issue and it wasn’t; then we thought it was the ECU so we tried it in my Del Sol and another 92 accord with H22 motor and it ran both with no problems….so we think it is a wiring issue…. Take a look at the spread sheet and see if you see something that might be causing this?

The excel file not allowed so tired to paste it below!!!

The only things I saw different were the Map sensor pin location that might throw the custom ECU off….

You have already determined it is a wiring problem, so now you need to track that down and correct it.

Why would I not have fuel pressure by just switching the ECUs? Looking at the Accord vs Civic(P28) cars ECU pin outs they are 98% the same especially the PINS that would activate the fuel pump and everything that is important to run the car.... I'm not seeing what the possible wiring issue is...

I was able to convert the Excel file to a gif image file...it is attached.
