1999 plymouth voyager remote start

Hello,I'm pretty experienced with alarms and remote starts but I just can't seem to get over an installation going wrong.I'm trying to put a remote start/alarm combo in a buddy of mines 1999 plymouth voyager,but keep having a peoblem with the tach signal.I have a wiring sheet,but the wire  doesn't read between 1 and 6 volts ac that it gives(gray/red or gray).Then I found out that because it has the 2.4 4 banger it's the blue/tan wire off the pcm,but that didn't read right either.This is what happens:the car starts (overcranks the starter)runs for about 2 minutes then just shuts off.Winters coming quickly and I don't want to let him down,any help would really be appreciated.Specs:1999 plymouth voyager,2.4 dohc,auto,no p.locks,no p. windows,no p. trunk,no tachometer.(pretty basic).

Each Wire Listed Above Is A 2 Cylinder Signal. 3.0L Tach Wire Is GRAY/RED At Powertrain Control Module (PCM). 3.3L & 3.8L Tach Wire Is GRAY/RED, D BLUE/TAN And RED / YELLOW At PCM (Each Wire Is A 2 Cylinder Signal).

Try a ODD Color Fule Injector Wire............

Or go TACHLESS
