I fixed the vacuum lines and now the truck wont start.
The fuel pump is not turning on. 7.1 volts at the inertia switch. 7.1 volts at the fuel pump relay and 7.1 volts at the #8 pin on the ecu orange/lite blue wire. I disconnected the inertia switch and still 7.1 volts. I unhooked the fuel pump relay and still 7.1 volts. Finally i checked the ecu and it only has 7.1 volts at the #8 pin orange/lite blue wire.
I guess the ecu is bad or am i missing something.
How does fixing vacuum lines/leak end up with low voltage at the fuel pump.........
Edit. I have continuity from the fuel pump relay orange/lite blue to the ecu connector pin #8 orange/lite blue. Both the ecu and the relay were unplugged from the connector. The grounds at the ecu are good. There are two that i could see right next to the ecu on the body. I had taken it to bare metal when i first bought the truck.
