I installed the HKS Twin yesterday and when i tried to start the car all the needles on the panel where going up and down and i didn`t have any power.After a few minutes the car started so i gave no attention to it. Today i tried to start the car and again same problem,no power for a few minutes.It is like the ECU is restarting or something... Any ideas will be help full


P.S I connected the coil plugs correct T-L and also grounded the HKS.

 

installed mine for over a year and a half and never had a problem. but i suggest you to probably check your plugs again and make sure its in the right order. i will try and snap you a pic if i have time.

 

I've never had a problem with mine either, check the connections.

 

Before you installed the twin power I hope you checked your coils. That would have been the perfect tiem to do so, and make sure they are in the correct order. It can happen..

 

Sounds like a bad ground. Check the connection.

 

Thanks for all the info!
For the coils i don`t think there is a problem(worked fine 5 minutes before)
The connections i would double check tomorrow but it is basic...White Tie - Black Tie
Might be the grounding.Couldn`t remove the ground screw so i drilled a screw for mounting the HKS and put the ground wire between the chassis and HKS.

 

Sounds like your problem then....that will be a very poor ground...unless you sanded off the paint to bare metal.....but it's more likely your battery ground...or connections. The HKS ground shouldn't effect the whole electrical system

 

Bad ground only for the twin power,
Maybe because the power goes threw the twin power and after to the coils and the twin power is not grounded well, it might creates this "restart".
Will have to check it tomorrow and let you know what was the problem.

 

The same thing happened to my car with the Needles.

The terminals on the battery ground were rusted and once I cleaned it up and replaced some parts, it had a much stronger ground, and started like normal.

 

Yep, it was the grounding!
Thanks for the help
