Fuel issue on a 90 Tona shelby VNT

[shelbyplaya]

i cant for the life of me figure out whats wrong with the fuel systum on a 90 daytona VNT i'm working on.

the pump DOES work and the motor DOES run. if i hard wier the pump so it stays on the motor runs fine. i'm not verry good with electrical. i've changed the SBEC, fuel relay and the hull effect. not getting any codes.


anyone got any ideas?

i've also checked all the connections..

what exacly is the problem? Pump not running unless wired to the battery? Try fuel pump relay?

Have you checked the wires heading to it? Maybe one is broken or shorted.

jump a wire from the battery to the pos on the coil and see if it comes on, if it does then that eliminates a broken wire going to the back

check the ASD relay too, unless thats the fuel relay your talking about.
