2003 buick park ave rs problem

Hey All, Had a Park Ave come in today with a non working rs from another shop that has closed. It was an Ultra Start that wasn't starting the car, but the locks/trunk worked. I reprogrammed the tach and it started twice then quit starting the car again. I pulled the Ultra out and installed one of our Autopage rs-600's. Same problem as the Ultra, except I haven't gotten it to start the car. Locks/trunks work, but when I go to start it, a relay in the unit clicks once, then nothing, no output on any of the ignition/accessory/starter wires. I can do RS take over and it will keep the car running. The tech at Autopage said he thought it could be a lack of voltage issue in the car. I am pulling power straight from the battery and have tried starting it with the car on a charger. Ground is on bare metal in the kick panel. I have power to all power wires at the unit. Any help would be greatly appreciated. I get the car back again tomommrow. Thanks.

Sounds like a PK3 issue...maybe???

12v power is run straight from the battery. When I hit the start button on the remote, I get one click from an internal relay on the unit. No output on an of the ignition wire from the unit. As for the PK3 issue, the RS should output power to the ignition and starter wires. The PK3 has no effect of the outputs of the RS unit, only weather or not the car starts.

Oh, tach wire is good and the unit sees it and programs to it. Lack of a tach signal still would not keep the unit from outputting power, only keep the car from starting. The problem is the unit does not put out any power to the ingition/accessory/starter wires, not that the car does not start. I have tried another unit, so there is something else that is going on that is not right.

When you removed the old system you you remove it from the connections or did you just splice into the existing wires from the previous system ? Make sure that the connections are soldered from the previous system but it seems to me like a cold solder somewhere, fusing issue or a ground issue.Jeff

I completly removed it and made my own connections. Just like I was starting from scratch. All connections have been trippled checked. Would the only connections that would cause something like this be the power/ground/neu safty/hood pin/brake wire? They all check out fine. This is why it's giving me such a headache.

Well, it looks like it was some sort of low voltage issue with the car, even though I could never confirm it. We had an old code-alarm still in the stock room so I tried that. I connected it to the other starters wires so all my origional wire connections were still the same. This made it so the only change ws the brand of the RS. I also had a bypass issue. I confirmed it was a double problem as after the install of the new bypass and the code working, I plugged the autopage unit back in with the new bypass and it still did the exact same thing. So in conclusion, it took a swap to a different brand unit.
