Now, the reason for my question.

With the pump jumped as I stated above, the pump is running, but the truck will not start. Just cranks. (yes fuel is getting to the rails)

BUT, whether the jump wire is hooked up or not, spray starting fluid down the TB, and it tries to start just on the starting fluid.

I unwrapped the harness from the relays back to under the washer bottle, all factory splices look good, no corrosion or loose wires. I don't want to redo all the factory splices at this point just for a slim maybe.

*sigh*


the injectors are fed a switched 12v, switched by a relay turned on when the key is in run. The computer will pulse the ground to fire the injectors. Back probe your injectors with the key in run and see if they are getting 12v. I am thinking the 12v that feeds the fuel pump relay is also the same 12v that feeds the injector relay.
