1. Ensure that all connections are well soldered and properly insulated.
I am certain all connections are solid as I made sure to check each one after I wired them up one by one. I will check again though. Insulation wise, I probably used more insulation then I should, but I wanted to be certain there was no shorts anywhere.
2. As mentioned previously, the R/S's chassis ground wire should have a soldered on terminal ring and be bolted to a good chassis ground point.
Terminal ring was used. I verified chassis ground in multiple places on the chassis to make certain I had a good connection. All seems golden. Will check again.
3. Were you having start-up problems before ( due to the Passlock2 ) ? The PLJX "learns" the Passlock2 value during programming, so if that is off and / or the wire connections aren't perfect, it could account for your engine start-up problems. Are you getting any "Security" type dash lights during the failed start attempts?
As stated previously, what happened yesterday was....
I initially programed the PLJX without having the 4206p installed. (I had all wiring run for the 4206p just didn't plug it in yet) After I attempted to program the PLJX I plugged in the 4206p and then also connected the 4206 blue/PLJX brown as I believe I had programed the Passlock correctly. Then I proceeded to learn the tach. Then programed the remotes/fabs.
Once I believed I had everything programmed I went ahead and attempted to remote start the car. All that happened was I encountered "7 Blinks" from the marker lights. From the diagnostic that had something to do with "manual mode enabled". So I went through the menus and changed from manual trans to auto.
Once I fixed that I again attempted to remote start. It tried to start but did not. A couple seconds go by and it tries to start again. Typically when I initiated remote start it would try to start like 3 or 4 times. If it did not start by the 3rd or 4th try in the sequence it would pop the trunk... Then I believe it stops trying to start.
I tried a few more times and then eventually I encountered the THEFT light... So I attempted to start the car via the regular key. No dice. Wouldn't start that way either
So I went ahead and disconnected the battery. Waited a bit then plugged back in. Once theft light was gone I started the car via the regular key. Once that worked I reprogrammed the PLJX. This time around I had the 4206p fully connected, just unplugged the blue 4206/brown PLJX wire. After it was programmed this time I connected the blue/brown wire again.
At this point the battery seemed a bit low so I threw a battery charger on it and waited. Once the battery charged a bit I went ahead and remote started the car.
All seems fine. It starts no problem a few times. Plus its also 15 degrees outside so its kinda starting slow. So I called it a night.
So I go back today and remote start. Starts up multiple times no problem. I finished wiring up the brake switch and trunk release.
By this time its about 4pm and temps are at 20ish degrees. Battery seems weak as I try to start via the key. Slow start. So I went to get a new battery as the old one is 3 years old already.
Plug in the new battery and start the car with key. Then I attempt to start once (starter cranks a few times then stops) Does not continue. I shut down remote start. I try again. Now it starts.
Since the new battery was installed I tried starting a few times and no problem. I just started it 2 times from inside the house and no problem.
So, I'm not sure. Maybe its fine now. Guess I'll watch it and see if it happens again. If it encounter the no start/ trunk pop or no start (cranks once then stops) I'll let you know.
4. As you found out, programming the R/S with the remotes is tricky. Due to the failed start-ups and re-tries, I would verify that the R/S is in Tach Mode and re-learn the Tach signal. Another thought, does the Malibu have "one-touch" starting? That is where the car will continue to crank the starter motor and get the engine running with just a quick turn and release of the key to the START position. If it does, you could program the R/S for a fixed crank time and let the car do the rest. Also, check the R/S's shutdown diagnostic for a reason / code for the failed remote start attempt.
I believe its in tach mode as it starts and runs for now. I will check again though. If it wasn't in tach mode wouldn't it not start and stay running like it is now?
Malibu does not have one touch.
I can check the shutdown diagnostic. Is the code stored for a while or no? I mean, if I try to start and it doesn't then it eventually starts is the code still stored or is it cleared.
