Fried 2 ECU's... Maybe grounding?
Alright friends, I'm back with another problem!
A few weeks ago I finished installing my b20vtec setup. At the time, I didn't have a gsr distributor, so I cut a lef off the ls one, and bolted it up. Worked ok, but it needed a new rotor,cap, and coil. couldnt see spending money on something I was going to replace anyways, so I went out and bought a refurbed GSR dizzy from napa, along with a new cap and rotor.
Went home, put it on the car, went to start it...nothing. The starter will wind, but it does not pulse like it normallt does upon startup. I was confused so I started looking for problems. At first I thought my t-belt snapped... its perfect. All the fuses are good under the hood, and dash. just for fun, I put my p28 in there to see if it was the ecu, and it fried! I went to start the car and the ECU started smoking, so its done. Why would it do this?
I have one idea as to what it might be. I took off all my stock grounding lines from the motor and tranny to the body, and replaced them with the Buddy Club Racing Condensor . Could this possibly be my problem? Would the motor/trans not being ground properly fry an ecu through the dizzy?

pics? i might becuase i put a wiing harness off of a b18b1 on the motor (obd1 gsr head, b20z bottom), so some of the wires had to be exended. Are they the round 2 pin connectors?

Re: (93eg2james)
I have no pics but the IAT is the little white sensor thats on your intake manifold and the evap is the sensor that has a funny cap on it and has 2 vac. lines coming out of it. What i would do is disconnect both of those and see if the car starts correctly, if it does then that was your problem. Good luck.
