Hello people First of all, it's an sr20 in a '78 280z in which my brother and I did everything except the wiring which was done by a shop (with a new "Painless" wiring harness). Right, so earlier this week the car died on the way home so we towed it home and found out the fuel pump was not working because it was not getting power. With some tests with a multimeter, we concluded the wire is broken somewhere in the harness. Instead of following the wire through the maze of the harness to find the problem, I wired the pump directly to the battery, with a toggle switch, and the pump definitely works as it makes a sound. But it still wont start. It cranks fine, the fuel tank is full, but it wont fire. What could be wrong? Is it not ok to wire the fuel pump directly to the battery? Is the problem somewhere other than the fuel system? Thanks!
