hi all hope you can help..i m having problems getting my na to start ..no injector or key code lights on ..Ive reset the timing properly so while the rocker cover was off today ive been checking the voltage from the connectors to the injectors but not getting 12 volts ..is this what it should be? I also noticed that the throttle position gets warm with the key at MAR ..Is this normal or is this yet another gremlin i need to sort out ...thanks in advance

A normal NA, not a VIS?

Assuming a normal NA, probably a dodgy injection relay, that's one of the 2 (the fuel pump relay being the other one) above the ECU in passenger footwell.

Both those relays (and the fuel pump fuse beside them) have to be OK to allow starting.

Or maybe the EFI maxi fuse if there's a lot more dead in addition to the injectors.

If it's the injection relay you won't hear the fuel pump priming when ignition is turned on, so that's another clue.

The TPS is a variable resistor so it might get a little warm.

If you just swapped the 2 relays around then sounds like the injection relay was faulty and now you've switched it to fuel pump relay so you'll now get power at injectors but no fuel pump.
