Please help! SC400 won't start!
Just bought my 93 sc400. Ran and drove until I took the old crap radio the guy had in out. I cut about 3 wires that were hanging by the gas and brake pedals. After I removed the radio and cut those wires, nothing happens when I try to start the car. With the key in the ignition the doors ding when open, and the dome light works. If I turn the key to the on position, the dash lights don't come on, the windows don't roll down, sunroof doesn't work. Nothing seems to be working. When I try to actually start the car, only the airbag and battery light comes on. No clicking, no trying to start. I don't have much money at the moment, any help???

What compelled you to cut wires by the brake/gas petals instead of getting a wiring harness and doing it the correct way? Perhaps you blew a fuse in the process? What kind of stereo did you uninstall/install. Did you take the negative battery cable off when you did this? We need pictures to better help you.

Ok so the wires had nothing to do with what went wrong. Ended up blowing a 40amp ignition fuse. Replaced the fuse and started right up. Since then the dash lights flickered. So I unplugged the standard alarm. Still ran fine. Shut the car off and went to go leave, and all it does is crank. Won't start. Then I replaced the main EFI relay. Started right up and ran better in my opinion. Drive it to my sisters 2 miles away. Went in for 45 minutes and came back out, won't start. Cranks and cranks but won't turn over. Any ideas?

Update: I did the fuel ecu mod. Starts right up, but when I'm driving doesn't seem to run up to par. Keep in mind y car does need a main o2 sensor. What affect could the main o2 being bad have on my car?

93 sc400 still won't start!
Ok so the car wouldn't start, I replaced the EFI main relay and it started up drove to my sisters, sat for about an hour and wouldn't start. I did the 12v fuel pump ecu mod. The car started right up, drove it around for a test drive. Parked it this morning for a couple hours, went to leave and it won't start again. I don't know what the issue is. It just cranks but won't turn over just like before. Yet everytime I switched something it would run (once). Also while looking under the hood I found this wire pretty much disconnected. The one on the left plug. I reattached them but nothing. Was wondering what that plug does? I also tried the coil trick to see if one of my coils was gone. I can only find one (the one next to the battery) where is the other?

I have the same problem on my 95 sc400 and trying to track down a wire problem. If you get your figured out hope you post with some results. If I find mine I will keep you in the loop.
