anyone know where the stock ground cable to the engine block is located at? pix would help a lot

 

Hey guy there is three grounds one off the valvecover that goes grounded too the from core support and the second one should be off the tranny too the chassis of the car and the third one is where the thermostat is at that grounds the engine harness .

 

Where at the valve cover n to which part of core support, i dont see it.

 

I do not believe that a stock S has a ground from the valve cover. You simply need to add one from one of the bolts to the grounding point by the battery. As for the other ground there is one on the driverside that goes into the block, it may also be the same place that a support goes to. I can't recall exactly as I had the tranny out last year and had to undo a ground wire in that area. I will dig around and see if I can get a picture for you of the ground locations.

 

thanks a lot! but yeh, i found out my starting problem was because i have to much resistance on the ground side and it cause voltage drop significantly so that the aem will fire up. using my jumper cable and grounded from negative terminal to engine block and another negative terminal to intake manifold and car will start up.
