This is an update to an earlier post
Driving 97 Land Cruiser and the square orange light above the dash volt meter came on, I assumed an alternator problem continued driving home. Made one stop and left vehicle at idle for about 5 minutes, it died and would not start, it would turn over but CEL did not come on when the key was turned on.
I have followed the recommendations on the " Emergency Troubleshooting Procedures" that is posted on the IH8MUD site
1. Checked all fuses with ohm meter all good.
2. Checked 3 wire fusible link, it checked good, installed new one anyway
3. Replaced EFI relay under the hood, with key turned on I can feel the relay clicking when plugged in.
*CEL light would not light and still have no spark but starter still turns over.
*I put a jumper between the normally open contacts were the EFI relay plugs in, the CEL light now comes on but does not start.
4. I removed the fuel regulator bypass hose no fuel came out when ignition is turned on
5. Headlights, Turn Signals and Taillights do not come on this would normally indicate that that the Main Fusible link is bad but the radio comes on which is on the Main Fusible Link.
6. I have pulled apart and cleaned all wire plugs in the driver side kick panel
I believe the normal dash lights and indicators come on when the key is turned on except the CEL light
I plugged in a OB2 reader and get the message that the cable is not plugged in. Were do you check to see if the computer is getting power
The only way to get the CEL to come on is jumping the normally open contacts were the EFI relay plugs in and sometimes I have to switch the ignition switch on and off several times for it to stay on. Could be the ignition switch is bad ??
Thank you for the help
