Have a 94 Chevy pickup 4.3 liter throttle body injection unit been sitting for couple years cuz bad trans . during couple years I started it up couple times and idled smooth. I finally changed transmission and now it won't start. I disconnected fuel line behind TBI and fuel pump is working but it won't fire. Would it be injectors? Or how can I test those injectors ? The injector wires have 11.8 volts. Also disassembled injector housing and nothing was plugged up. Truck always ran smooth. Could it be bad gas? All fuses are good

I checked all wire connections and vacuum lines everything is connected I'm thinking its just weak gas . we added about 3 gallons of fresh gas but no treatment. Fires with ether but wont stay running

Make sure the oil pressure switch is plugged in. Are the injectors spraying?


Ya I found my problem. The injectors were spraying just not enough I guess. We dropped fuel tank and a rubber hose on fuel pump was rotted and had a hole in it and the rubber was plugging the pickup tube. We changed little fuel hose and cleared the line and the truck started right up
