I have a 2001 Eclipse the alarm is hooked up everything works but when I try to engage my remote start the starter turns over but the car doesn't crank. If the car is already running and I engage the remote start it will stay running, but that's it. What could the problem possibly be....

What are you using for the transponder bypass?

Might I add the alarm has been in the past installed and worked properly . And with the type of connectors the shop used it was a matter of makings sure I was making the correct connections. When I first hooked the alarm up the car was starting and would run right for about 5 seconds and then the RPMs would drop and it was making some funny noise. But as I said earlier now it just turns over but, won't start...

To rule the 556U in/out as the source of the trouble, try any of these things:
--There's a green light in the car's dash, with a picture of a car key. Try the remote start, while watching the dash. If the green light is flashing, the car is NOT seeing a valid key.
--Unplug the 556U, insert a good key in the ignition (but don't turn it), and try the remote start.
--If the remote start works fine with a key in the ignition, there must be a problem with the 556U........could be the unit itself, the ring around the key cylinder has moved, the ring is bad, or the U is miswired.
Hint: There's a small relay inside the 556U, and you should hear/feel it click on when activating the remote start.
If it doesn't click, start testing to see if it has constant, ground, and ground-when-running from the remote start.

Thanks I'll give that a try tomorrow evening but, I do know that if a key is in the ignition not turned the remote start will crank it I noticed that today and also if the car is running already and the remote start is engaged the car will stay on once the ignition turned off and the key is removed...

Basically you've confirmed that your bypass is not hooked up properly but the remote starter connections are all fine. ------------- The search function is your friend.

but this is the thing it was already on the car previously I just put it back on. when it was on the car it worked perfectly so does that mean that the bypass is gone bad....

Check all those connections to the 556u again -- as Chris suggested make sure the relay is clicking in the 556u and the antenna loop is wound tightly around the key cylinder. You can use electric tape to secure a tightly wound antenna loop when you've verified that it's working properly. ------------- The search function is your friend.

Also make sure the key inside the 556u is still appropriately positioned.

The head of the key should be centered in the ribbon that encompasses it. Why did you remove the r/s from the car if it was working appropriately? I musta missed that

oh I was going to trade the car in and then decided not to...it was dumb on my part the thing is the shop only charged $40 to take it out but wanted to charge $150 to put it back in....

Ok I think the 556U is gone bad because I've tried to reposition the key and it keeps doing the same thing trying to start but, does not and I did see the little green key flashing in the gauge cluster so I guess at this point the only thing I can do is change out the bypass right... Oh yea the bypass clicks but I guess it's still not functioning properly cause it's still doing the same thing and the key I had inside the bypass I put it in the switch and hit the remote start it started right up...

It's still possible that the ring around the key cylinder isn't positioned correctly.
Try moving it around to different spots, and making it tighter around the key cylinder too.

I figured out what it was it was the ring around the key cylinder...

Alright I got everything working my next question is where is the best place to mount the brain unit and key bypass...

Depends on how "stealthy" you wants to be... I usually install the brain via zip ties to the right of the steering column shrouded in some soft foam (to prevent any rattles or vibrational/impact damage to the brain). If you feel you want to be more aggressive about security, I would consider mounting the brain behind the center console or behind the glove box. This may require that you extend many of the wires that are already connected (can be a pain, but very worthwhile if you want to thwart crime as much as possible). The keybypass I usually mount near or next to the r/s brain, also varying in terms of location. It would probably be smartest to mount the bypass in a polar opposite location to be more aggressive about security. ------------- The search function is your friend.
