Fuel problem

I have a GSU, when I turn the engine over I have spark but the fuel pump does not come on and the injectors do not fire. I have replaced the injector relay under the dash. If I run a wire from the batt to the fuel pump it runs but the injectors don't fire. Any help would be helpfull, thanks.

the injectors are not getting the signal to fire from the ecu or the egi fuse is blown or missing., check the fuse first

I assume that you have a GTU, not a GSU... In that case, is your CEL on?

1. The fuel pump only runs if THE KEY IS HELD TO START.

2. OR the if the engine actually starts and the vane in the afm has moved aft.

3. The fuel pump does not work if the engine is not running and the key is not being held to START.
