Need help with ground wire locations and fire issue 3vze

Hello, I have a 1989 pickup with the 3vze. Just did a valve cover job and new denso injectors, spark wires, plugs, misc coolant hoses and a sr5 gauge swap. I installed new injector pigtails, connecting the red from the new connectors to the white wires on the oem harness, and the black to black. I go to crank it after reassembly and it stumbles and trys to run a little but can’t. I feel like I hear the injectors clicking strangely but I’m not sure. I’m also wondering if one of the ground straps near the back of the engine is not in the right position. If possible, I would really appreciate a picture of where the ground wires near the back of the engine go, I’ve counted 3 so far, 2 of them dual wires, one is a fusible link. Currently I have the fusible link ground going from the body to a bolt underneath the intake plenum, possibly the head. I have a dual wire ground going from body to top of intake. I have circled in green where the fusible link, and another dual wire ground is bolted to. Any help or guidance is much appreciated! Thanks
