So I want to wire a relay to kill the PGMFI and i have decided to use this method posted in another thread by fcm..

where can i find the PGMFI main relay? Is it under the dash or under the hood?where is it located?

thanks

Main Relay is under the dash

which wire do I cut for the ground? I think I found the main relay but there is no solid black wire?

What kind of car do you have. The main relay is not allways under the dash.

its a 2000 civic

It is in the pasaanger side dash pannel. Open the door and pop off the pannel. Unbolt the 10mm holding it in place. Unplug the main relay and pull down the harness. Cut the zip tie holding it there. No go ahead and work your magic on the kill switch. Hint relocate it to the top of the dash and make the sure that you keep everything looking stock. Do not bolt it back in the stock location because a theif might try to tamper with it once he figures out that the fuel, injectors do not work. And it will not be there for him or she to have access to. You can hide it close to the same spot with out anybody seeing it or tampering with it. I do it all the time.

Really it is. And it will throw a theif in a wtf state.

alright so i have this relay all wired up exactly like in the first post.

The alarm is a compustar cm3000 and i tapped into the black status output wire. the problem is the car wont start. I can start it if i reconnect the ground wire but as soon as i run through the relay the car will not start.

the ground is good, it is also the ground for something else that works. 12V constant is the same as used for the alarm.

The other weird thing is that when i try to start the car with the relay hooked up the alarm will no longer work and i have to reprogram the remote.

i would do the relay like this

86 to neg when armed or a switch
85 12volt pos
87 one side of cut ground from main relay
87a other side of cut ground from main relay..

can anyone else confirm that that will work with the remote start?

doggworld1233

the problem with doing this with a R/S is that i dont remember if neg when armed is still a neg when using the r/s..... i cant think of a way to make it work with a r/s right now and still have the car start with the key.

It will not work with remote start as GWA is active until alarm is disarmed, it also means relay is energized any time alarm is armed.

91sihatch I am not sure what your problem is, if PGM-FI Main Relay kill relay is wired as shown it should work.

First thing I would do is change the 12V+ constant #85, the alarms power lead should be on a "clean" source, [not used for anything other then alarm when alarm is armed].

Recheck the other wiring to the kill relay...

#85- Use either the PGM-FI Main Relays constant power or it's "true ign. power.
# 86- Compustars GWR, [black status output, normally C2/2].
#30- Cut ground lead from PGM-FI Main Relay.
#87a- to kill switch then to other cut end of PGM-FI Main Relays ground, [ground side]
#87- to chassis ground

If the GWR, [status] lead is also being used for a transponder bypass module or Clutch Interlock Switch bypass install diodes on the status leads before the bypass or CIS bypass and the kill relay to prevent the bypasses and kill relays form interfering with each other.
I do not believe a 2000 Civic came with an immobilizer/transponder key.

Where did you get the Compustar from?
Make sure status output is working, unplug it from #86 and ground #86 directly to chassis and try and start the car.

Questions...

What exactly happens when you try and remote start the car with relay wired?

Engine will not crank.
Engine will crank but not start. 94

12V constant for the alarm and relay comes from the unused 12V constant in the under dash fuse box. That should be an uninterrupted source?

Rechecked the wiring and it is fine. The black status output is only being used for this relay. I bypassed the CIS when wiring in the starter kill.

There is no transponder/immobilizer and the alarm was bought from an authorized dealer.

I will try to start the car with the status output lead grounded and see what happens. I have no tried to remote start the car with the relay wired because the car will not start under any circumstance, so i cant even set reservation mode.

Maybe i have a faulty switch. I am going to check that next.

thanks for the help.

i dont know what is going on. i have triple checked the wiring, tried another relay that i know 100% works and tried a working switch but still nothing. The car will not start

also it appears something is draining my battery since i had to boost it today. i have a fuel relay wired like this: i ran dash fuel side to poles 30, jumped 30 to 86.. and ran the 87a to the fuel pump and 85 to a on/off switch and then to a chassis ground. could that be draining my battery?

fcm

It sounds like the fuel pump relay is causing your problems, if you have a PGM-FI Main Relay ground "kill" relay installed, there really is no need for a fuel pump power lead kill relay, once the ground on the PGM-FI Main Relay is interrupted, there is no power to the fuel pump, so the fuel pump kill relay is redundant.
It also means if the kill switch is on for the fuel pump power wire kill relay, when you go to remote start the fuel pump kill relay is energized so not power to the fuel pump.

As for the drain on the batt., make sure no relay is wired so it stays on when cars ign. is off, with alarm armed or not. 94
