About a month ago I had a Viper Security/remote start system put in our LX450. It and everything has been working fine. About 5 days ago my wife said she had a few problems while driving. It actually died on her in traffic. It started right back up though. The other day she said she had problems unlocking it and had to do it manually. The following day it would not start with the remote start, but would with the key. The next day it would only start with the key but would run and then die...then start and run rough and then fine for the rest of the drive. This morning it didn't give me any problems starting and got me home and then this evening nothing. It wouldn't start the first crank....started the second and died after 3-5 seconds. That was it. Couldn't get it started after that.
I spent a few hours tonight tearing into it thought it might have had something to do with the remote start as the VIPER was clicking non stop and would not turn off until I disconnected all power. Finally after some playing around got the alarm not to go off but still no better. Tried to bypass the system and still could not get anything. Now the system will not work at all. It won't unlock doors, remote start or anything. Strangly it will show the system is armed with the LED and unarm it but no noise out of the Speaker and it will not unlock the doors.
Test #1: I am not getting any spark at the Distributor.
Test #2: I am getting power from the ignitor but only 6-8 Volts depending on what I have plugged into on the VIPER and only 3 Volts when cranking.
Test #4: Ran 12V from a jumper to the Ignitor and still no spark at the distributor.
Test #5: Tried to see if the immobilizer on the LX450 security system was cuasing problmes (don't believe it to have anything to do with it as it all check out).
So I hop on mud here and read a few thread about the EFI...I think I did check that but now I am not sure...is there more then one spot and where is that fuse.
What I am thinking after reading all of this is that I MAY have a problem with my fusible links as they cause all sorts of wierd electircal problems and this may be effecting my ECU.
Any help here. I have until Sunday night to get this up and running for my wife for the week.
Thanks.
