Hey guys, made a similar post to this but probably named it wrong. Anyways as the title states I've got a b16 turbo I've been building in my 91 integra that just wont start. It cranks all day but nothing. The exhaust pops like a SOB, I would think its running rich but I have the stock injectors in, and fuel pressure is below 40 or so. I have put back everything stock when it comes to obd-1, that being the dizzy, injectors, map sensor and ecu. It does have a 255 walboro pump in it, which I know works because I have fuel to the rail and I also have spark. I don't see how the cam timing would be off as I haven't done any head work. Any answers would be greatly appreciated.

Thanks once again lmao

 

Just realized I said I put everything Obd-1 back, I meant OBD-0, I do have all the OBD-1 parts just took them out.

 

What ECU do you have in it? Is it for the OBD0 B16?
Did it start “before”? As in was it starting, then you added the turbo or other part and now it’s not starting? Or have you never had this set up start at all…?
Are all of your fuses good?

 

Stock Ecu for the OBD0 B16, The car was running fine before I started the entire turbo setup. I've been working on the thing on and off for just over a year now. Just emptied all the old fuel that I assumed was bad and put fresh fuel and plugs and still nothing. Fuses are all good, one thing is that I removed my resistor box for a set of high impedance injectors which I found out weren't working so I put back the stock injectors for right now and have just twisted all the wires for the resistor box plug back, haven't soldered them. Do the red wires have to match up to specific ones that I cut or can they just connect to which ever one?

 

I don't think twisting them together will give a good connection, they should at least have wire connectors. They don't need to be soldered though. I assume the red wires have to be connected to the specific ones. I don't know though.
Are you getting a check engine light?

 

It IS important that the red wire of the resistor box goes to the yellow/black or black/yellow 12v+ feed wire from the engine harness and all of the fuel injector 12v+ wires (yellow/black or red/black) connect to the 4 remaining black wires of the resistor box... and no particular order is required.

 

Just double checked the wiring, The black/yellow goes to black/yellow and each red/black wire is connected to the other, no particular order. Still popping like hell, any other reasons it would be popping so much and not starting?

 

Wrong firing order of the spark plug wires on the distributor ?
