I recently had a Radiostar King-Eagle alarm&r/s combo installed, the installer first hooked up the tach wire to high-voltage and the remote start kept overcranking and then shutting down the engine. The installer then connected the tach wire to distributor and remote start worked. About a week later (during that week I used the r/s maybe twise and both times it worked) the system started overcranking again. The installer then tried the following:
- Connecting tach wire to oil-sensor wire
- Connecting tach wire to fuel-injector wire
- Changing the alarm brain
- Changing the remote start module & the brain
System still overcranks! At this point the installer says that he tried everything and the problem is that the brain is not reading the tach signal. Is there anything else he (or I ) could try ? Maybe he screwed up the wiring somehow ?
The car is a 1995 Nissan 240sx 5-speed
Thanks in advance for any advice !!!

If it's over cranking it's because the tach signal is not being acknowledged by the remote starter CPU. There are 4 injector wires that you can use, did he try using one of the other 3 ? Aside from this, you should try a Compustar brand instead of the Radiostar.

Further note, some remote starter brand unit require a higher tach signal read in order to have a smoother cranking release. If the tach signal is low, overcranking will be an issue. Try a different tach if there are any you haven't test or change to a different or well known brand of remote starter altogether.
Be careful whose advice you buy, but be patient with those who supply it.Remote start overcranks in 1995 240sx -- posted image.

He tried the oil pressure sensor wire? Now that's just funny and has nothing to do with the tach signal. The injector wires should work, but they fire at a rate that's 1/4 of the actual engine rpm. Let's just hope he used the pulsed ground from the ECU instead and not the BLACK/ red positive feed.
Did he try using the tach signal off the ECU? (ECU pin# 3, yellow/red wire). Also I'm not familiar with that alarm brand, but could it just be a brain programming issue?

Thanks for replies. I spoke with the manufacturer about reprogramming the brain (since i want to sell these), what would you say the values should be for the tach sensitivity in terms of voltage ?
Installer also suggested that the car may need a tune up (timing belt), you think that can have something to do with the problem ?
also about the fuel injector wires - i only see two wires coming out of each injector, which other ones should I try ?
Thanks a lot!

Use any wire that is not common in color.

how can u ask such basic questions on installation and say you want to sell those alarms..? Who are you going to sell them to?
Why do ppl always try to get away with these non proven, no name alarms? Maybe I am off base.... but it seems like a no name brand to me.
Our shop sells Autopage and Avital exclusively...... 99% being Autopage.

Tach voltage sensitivity?!! The tach signal doesn't give out positive voltage, it's a pulsed ground. Also your installer said you need a timing belt?! Wow, you should fire your installer... your car doesn't have a timing belt!
As for the injector wire, as I said in my post above and what Jeff repeated, DON'T use the BLACK/ red postive feed wire. All other colors are ok. Maybe these brains are bad, cause your installer keeps feeding voltage into a wire that's looking for a pulsed ground.

Thanks guys, I will try to figure it out myself since I have a feeling this installer is almost as clueless as I am.
Should I try the tach wire with distributor wires? If so what color/s ?
