I have a problem where the car refuses to start. The check engine light comes on and the D4 light blinks. When I hooked the jumper to the Diagnostic port I got the following error codes on the D4 light:
1
2
3
7
8
14
According to these, I have a bad MAP sensor, a TPS problem, an oxygen sensor problem, a bad TDC sensor, and an Electronic air control problem. The car ran fine up until it decided to not start so I highly doubt all of these could be bad. Is there anything that is related to all these sensors?
I appreciate any help I can get.
Also, it sounds like a relay is not turning on when I put the ignition into the on position. If I sit in the car for a minute or two, I can hear what sounds like a relay switching and the check engine light goes off but the D4 light will still blink and I can't start the car.

bring it to auto zone and ask them to put a obd on it

Ok, this can be locked (or whatever) because I got it fixed.

To clear the codes for the MAP sensor, I pulled BOTH fuses labeled ECU under the dash and cycled the car to on. I pit them back in and cycled the car to off and then back to on and the alarms haven't came back in the half a dozen times I've drove the car since.

To clear the other alarms, (this is embarrassing) I plugged the TPS sensor back in. Apparently I unplugged it when I was looking for vacuum leaks.

I hope this helps someone in the future.

How about this? My '95 SI just decided to die on me and not start at all. Checked the Starter, it passed a power test. Now I'm leaning towards fuel filter and/or pump. Need a little help here before I start ripping it apart. Since Chiltons manual is just about useless. Unfortunately no Haynes manual.

Do you get spark? I had an ignitor die on me in the middle if traffic before and it sounds like what you are saying.

What do you mean Igniter?

I believe by ignitor he probably is talking about your coil, and you can check that by pulling any spark plug wire and checking for spark. Also:

A: Pull your distributor cap, rotor bug could have blown.

B: when you turn the key to "ON" (not start), can you hear the fuel pump fire up (soft hum from the back)? Could be fuel pump, but could be main relay.

C: If those check out, could be ignition switch.
