This install is for a 2014 392 in a '69 Charger. I have the 'Crate Hemi Engine Kit' - 77072454AB. The engine runs - once it starts. Multiple cranks, sometime several minutes.
I looked at the header - PDB1 (marked "PDBA on mine) going into the power distribution center. The 'FUEL PUMP FEED' (DB/Orange) is 18 Gauge, not 12G as in the Instruction Sheet (Rev 5.0). Also, that wire does not get 12V at Key-On, and the "FUEL PUMP RELAY CONTROL' wire next to it on same header does not get 12V at Key-On. I wired my fuel pump from another fused source to bypass this problem.
My problem is that it takes several minutes of cranking to fire the engine. Minutes - try, stop, retry, again. It should fire immediately. I have checked fuel line and there is plenty of fuel coming out of it if I disconnect it.
Are these problems related? Does the ECM have to see a load on the fuel pump circuit to send spark? Even if that were the case, why does the engine start after several minutes of cranking - it should never start.
Also, has anyone with this engine kit had a miswired or mislabeled PDB like mine? It's really concerning that the instructions are different from the actual wiring
