Thread: Intercooler installed but car won't start?

I have everything installed for the intercooler. I even filled the lines and ran the pump without starting the car just to make sure it worked.

The problem is that the car will not start. When I turn the key to start basically I get nothing. Almost like the battery is dead but I know it's not. The weird thing is now I can't hear the fuel pump start up either, the radio doesn't work in the ON or ACC position and my climate controls work on 2,3 and 4 but not on 1 or 5. Other than that everything else seems to be working. I hope I didn't screw something up when I was trying to plug the "Add a fuse" into different fuse spots so the ignition turn on for the pump would come on when I turned the key.

I am getting this code:

P0230-Fuel pump---Checked the fuses and even changed out the relay but nothing changed. The fuel pump was working fine before I started the install.

Could the ground on the coil pack be an issue?

I bought new terminals earlier today. I will try and clean the battery terminals tomorrow and try again.

when you say it doesn start, do you mean it tries to and just doesn fire? or when you turn the key nothing happens at all?

Nothing happens at all. Doesn't click or anything. I am thinking I need to take the coil bracket back off and check the ground.

I am also getting code:

P1546-Air conditioning clutch feedback circuit low voltage.

I think the first thing I need to do is check the ground for the ICM. Nothing sparked on removal but I did have the battery connected when I was trying to find a place for the "Add a fuse". Could I have blown something when I took the fuse for the fuel pump out and put the add a fuse in there?

Oh hey, did you remember to add a second fuse to the add-a-fuse?

Yes I had two fuses in the thing when I plugged it in.

I am pretty sure I did something bad when I installed the add a fuse. I have it back to the way it was without anything connected to the battery at all. I noticed the hazard switch, radio, 1 and 5 on the climate controls don't work.

Tried moving relays around to see if that helped and nothing. I also tried cleaning every ground I could think of. I cleaned the one to the battery terminal, under the PCM for the ABS and the ICM ground on the coil pack bracket. Nothing has worked yet.

I still don't understand why its not cranking at all. I even had someone hook up jumper cables to see what would happen. I was getting the power but the car wouldn't even click or attempt to fire. I turn the key and nothing is there.

Are you absolutely, 150% certain that you've got the fuse in the right spot? I know it sounds stupid, but I did this with a sunroof fuse and it drove me nuts for an hour before I started moving the fuse around.

Nuetral saftey switch problem?

It's a normal key and the same PCM but I was thinking it might be the security also. I will have to try a case learn tomorrow and see what happens. If that doesn't work it looks like I will be chasing wires tomorrow. I checked all the fuses and the starter is functional but not getting power for some reason--Same with the fuel pump and various other things.

I have a Monte Carlo so not sure if I have fuses in the glove box (I don't think I do). I can't hear the relay click or the pump prime. I pulled every fuse I could on the car and tested them. All the maxi fuses were good same with the smaller ones.

Explain the add a fuse thing more? Easy way?

I am starting to think its a relay or a few relays that are fried.
