I have a built b18b motor in a 1998 Integra gsr. The problem I知 having is that I replaced the throttle body gasket and the TPS sensor (yes u calibrated it) and I went to crank and there was no start. I have made sure the tps works. My mai relay works as well I have tested it with a multi meter (both relays). I have power to the injectors 12v. I also have a brand new fuel pump and it痴 priming (340 LPH) it seems that everything is good but the injectors are not opening. I plan to use the multimeter to check the grounds on the ecu. I also am running Hondata and COP kit. I have checked for spark on the plugs and they池e running strong but my plugs are super dry as well. Car only starts with starting fluid.

either ground wire is not connected, or timing is off

I checked all my grounds and timing isn稚 off.

Are you saying the new built engine ran fine BEFORE you changed out the throttle body gasket and TPS sensor ?

Ej1Gonzo

yeah bro after that it didn稚 work 😐 I was hella confused. I calibrated everything I even swapped the tps again and no luck

JRCivic1

Do you have the TPS and MAP sensor plugs connected to the matching sensor or are they swapped ?

Ej1Gonzo

I think this might of been the problem but yes plugs are in correct order

JRCivic1

How did a TPS and throttle body change burn the ECU ?

Ej1Gonzo

I知 just as lost

Try another known good ECU.
