Default car wont start after sensor mix up

turbo d16z6 in eg

I accidentally plugged the MAP sensor plug into the TPS. So the TPS plug was not plugged in at all. I also have a 3 bar MAP which is wired into the harness. The car would die at anything over tiny throttle inputs. I immediately pulled the car over and plugged everything in right but now the car wont start. No CEL. Hondata when is gauge display mode goes nuts and throws random numbers. I looked at the ECU and nothing looks burnt.

Im not really sure where to go from here. I'm gonna swap the TPS after work and test a different ECU.

Any suggestions on top of that would be awesome.

Check the ground wires. Check for 5 volts supplied from the ECU to the MAP and TPS.

It's not a ground because there is still power to everything. I will check for power to TPS

Not necessarily true. When you turn the key to ON(II), does the CEL come on for ~3 seconds then turn off? Does the car try to start but not catch, or does it not even try to start?

well after swapping on 3 different TPS and 2 throttle bodies it turns out that my brand new Motorola 2.5 bar map went bad. plugged the old map in and it runs fine. I emailed xenocron where I bought the MAP sensor and unfortunately they wont refund or exchange. But bright side the car runs again.

There's never any warranty on racing parts.

Of course, you need a different tune for a stock MAP vs. extended range.
