1998 Pontiac Grand Prix Starting Problem

Yes, I can look at a schematic to determine that for you. However, you need to tell me exactly where the wires are, their color, what they connect to. I should be on for about another hour tonight, so let me know. It's 10 PM eastern time where I am.

Yes, it should. Take a look at the wiring schematic I attached. Power from the 40amp maxi fuse goes to the ignition switch, then through the transmission range sensor then to the starter. The problem lies between the switch and the starter. The only thing you can do now is start back tracking to see where power is lost.

That sounds good at the switch. However, you are only getting 1.4 at the starter. Now we have to check between the starter and the switch. Most likely, the power supply has an internal break and is limiting the power to the starter.
