Re: Laptop Wont Connect To AEM!!!!
 

Bad ground somewhere, and now since it's hooked up to the gauge, it gets a ground? that's my guess.

Here is my update...
MFI relay works and fuel pump relay not clicking on.
Move the switch the relays and then the fuel pump relay clicks(which is acting as the MFI relay). So I know both relays are good.
4 wires on fuel pump relays.
Black/white-Ign power
Black/white-Ign power
White/red-Grounded throught ECU
Black/Blue-To fuel pump

Both black/whites get battery voltage when key is on
Connect one of the black/whites and the black/blue and fuel pump runs. so the black/blue wire is good.
Ohm check white/red from relay to ecu and get 0 Ohms(which means the wire is good.
Ohm check white/red from relay to chassis ground and get 5.94 megohms (5,940,000 Ohms) With the ignition turned off and reads 7.35 megohms with the ignition ON.

If Im not mistaken when the key is turned to the ON position It should read 0 or close to it because the ECU should dirrectly connect that wire to ground.

Figured it out. I grounded a wire and everything works.(i think)

Re: Laptop Wont Connect To AEM!!!!
 

Yup. It was grounding through that gauge before.

After you said that it made SOOO much sence to me. Thanks!
