I have a 91 tbi 5.0 v8. After rerunning some vaccum lines from the heater/AC controls and fixing some wiring I'm not getting any gas in the engine. I can hear the fuel pump start when I turn the key on but no gas in the carb. When I dump a little gas in carb it fires off fine? I also put a new fuel filter in. Any help would br great.

Thanks in advance for your help

Hook noid lights up to the harness in place ofthe injectors and crank the engine. Look for the lights to be flashing. If they don't flash then the ECM isn't seeing the refrence pulse from the distributor and won't fire the injectors. Look under the dash for any wires you may have broken or pinched.
