Remote start issues, starter dragging

Finally after some sub zero temps,,,it appears i have the remote car starter somewhat working.

I have to research this site some more for the answers, but if some one knows the quick fix that would be great.  It starts, but the starter stays engaged dragging, then remote control shuts car down.   From the manual, it appears this might be caused by a weak tach signal. or its needs to be tach adjusted again. I tried tach adjustment again and still the same....   I also noted off the distributor there is a PURPLE / white wire and this poss can be a better tach signal as it goes to the engine crankshaft sensor. I am going to try switching this out and see if it is the cause.

Any one have any other thoughts on this.

Sounds like a tach issue like you stated.  It would have helped if you included Year, make, and model of your vehicle. Chances are someone here has done that vehicle and can give you a good tach source.

Sorry bout that boomer.. :=)

its an 85 Olds Firenza.... I gave up on finding a tach source off the coil. I will be trying the PURPLE / wire off the distributor as another wiring diagram site, said it could be either the white or PURPLE / white wire off the distributor.  i also read somwhere, where a person was getting a weak signal for the tach wire and somehow tricked it  by revving the engine and then relearning the tach control.

boomer,,, I have a feeling that is the one,(PURPLE / white) and will be trying it tomorrow am... The Firenza wasnt in production long, and some of the wiring diagrams are generic to some degree... I found one site, that mentions for the 87-89 its either a white or PURPLE / white wire....I got a 85 and it has both white and a PURPLE / white coming off the distributor...

I have also ruled out a good ground tonight, by going right to the battery...Now the starter drags a tad longer.

While it was running, i put it in idle mode and taking out the key it continued to run fine and shut off with brake pedal press.. I also tried , with the engine off, ignition in the run position and tried starting it with the remote and it wouldnt start.   I do not understand this stuff fully at all, but I think and from what i read, the tach signal is the key.

It has two ways to program the tach and it only works one way in multi-speed tach programming. Trying the first way, auto tach programming it does not flash 5 times as it should.

I have to get the serial # when i go back out to try other wires. PURPLE / white off distributor and white or - post off of coil.  Its in a 1985 Olds Firenza.

I forgot, I checked the prostart/autostart website and its not in their list or i couldnt find it. This site, forum members and the search function has been the most help so far.
