RB20 won't start - code 13 & 43
So yesterday I received my manual boost controller. My car has been running extremely rich so I just installed the MBC then went for a spin, turning the psi up and monitoring the air/fuel. Was able to get to 13 psi on the stock turbo where the air/fuel was as lean as I wanted on the stock ecu. 11.7 air/fuel at 6K but redline was seeing 10.8.
Anyways, car ran great and came home to install the Greddy EMU. I had purchased the plug-n-play harness to make things very easy. Installed the Greddy stuff and had a friend come over who has tuned a few cars with the greddy emu. So he sets up the greddy unit itself on the circuit board inside and then proceeds to install a base map. Asks me to start the car to see how it would even idle. Could not get the car to start, just turns over. He said from what he could see on the laptop the car was not getting any spark. So after several attempts to get the car started we just decided to install the stock ecu back to normal. The car proceeded to not start, just crank over. So I check for fuel. Fuel pump primes, but continously. Check the spark plugs, and they are all soaked in fuel. So we check spark, but couldn't get the plugs to show any spark. We were not sure if you had to ground the plugs to see spark, so we grabbed a test light to see if the coil packs were getting power. Yes they were. So I unplugged the negative battery cable and called it a night in hopes it would reset in the morning.
Wake up and attempt to start the car and still won't start, just cranks over. Checked the timing belt and all is good. So I had a local rb20 guy come over to see if we could swap ecu's. We first checked what codes my ecu threw. Code 13 & 43. Checked tps and it gets voltage, but really high voltage. 9.33 v but when throttle plate is completely open it drops to .02 v. We swapped his ecu with my for shlts and grins and as we figured no luck. He had 22 code ecu and I have BH, but doubt that makes a difference. Anyways, I am wanting to give up. Please help...
