Autopage 850lcd help

You can go directly to the >>>> for the problem, but below I have listed ANYTHING you'd need to know about the problem

So, here's the scenario:I have a 98 Pontiac Grand Am and I recently installed an Autopage 850LCD, DEI 555L, and one power window roll-up module. I installed everything on Saturday and when I was done EVERYTHING worked great.So now heres the break down of the problem. On Saturday everything was good... had no problems at all with the alarm and all. Then Sunday I decided to make a couple adjustments on it. I turned the door check from 3 seconds to 30 seconds; I turned on pathway illumination feature; and I told the doors to lock after the remote start turns off (because my GM unlocks the doors after the remote start turns off). In addition to that, I siliconed up the hole in the firewall I used to run the hoodpin and siren wire.>>>> NOW, the problem(s)! Last night (Sunday night) I remote started my car... the car started, the remote told me and all was good. The remote got to 0:08 and then the car turned off... for 5 seconds, then turned back on, and the remote went back to 0:10... I was a little confused at that, but whatever I thought maybe it was a freak thing so I let it run... a minute later it did the same thing. Weird, yes. So I reset the remote (changed the battery and reprogrammed it to the brain) thinking that would help. Went for a drive, came back, got out of the car and armed it. Not 15 seconds after I armed it it PANICS and the remote tells me the door is open. So I'm thinking this is odd, because A) the door wasn't open; B) the dome light wasn't on; C) the alarm isn't even supposed to check that zone til 30 seconds, and even then it should give me a faulty zone alert (if im not mistaken). So I disarmed it and re-armed it and it was fine. Then this morning (monday) I remote started it... it ran through the whole ten minutes and was fine. Drove to lunch, armed it, it was fine. Drove to work after driving for like 45 minutes... armed it... PANIC and tells me the door is open.There's the scenario guys... this is getting old and embarrassing, but I do have ONE idea that might be the problem. The alarm, window rollup module, 555L, and trunk release relay are all grounded in the same spot... Could that cause this? Or did the silicone get hot and get on the brain or something? This is just really weird because aside from that EVERYTHING works as it should...If you read this much, I thank you deeply... I just need some help here, and I really appreciate any inputThanks guys!-Bob

Well I like mine other than the problems listed above... I've never had a problem with Autopage before (and I've installed two 650's and a 310) so this is odd to me.  Its not a bad unit when it works right, especially considering I paid $150 for it...

Do you think its possible that we both have bad grounds?  Or bad brains?

-Bob

Splitting up the grounds might be a good idea...

I used voltage sense for mine instead of tach sense and it works great... never over or under cranks it.  I've used this on all the autopage's I've installed.  What kind of car do you have?  Did you try using voltage sense?

-Bob

I am using voltage sense and I don't like it.  I am installing on a 2000 chev pick up.  The problem is that when it gets to about -5 or lower it takes longer to start than 0.6 start duration I have programmed.  So it keeps barely starting the motor until its flooded.  No good.  If I program it to start longer and it sounds horrible. No good.  jkj

Thats the time sense mode you are speaking of... not voltage sense...

You still have to program a starter time in voltage sense also.  Read the instructions carefully.jkj

I belive that is it exactly.  To see if it is running.  Take the fuse from your fuel pump circuit and then try to remote start.  It should try to start for the same short duration (after it burns what fuel was left in the rails) over and over as opposed to long bursts of continous cranking.jkj
