Truck in sig line is intermittingly not wanting the start with out moving the gear selector around a bit. I'm thinking neutral safety switch but not 100%. Anything else ?

I was out of town and I pulled onto road and the truckstalled. The day before it was loaking but drove fine. Got Error code 1689 (ECM Comm failure) Noticed no Fuel pres. Installed new Lift pump and newfuel filter... No fix Friends shop looked at it and run 12v to Inf Pump pin#7 andGrnd to #6(?). Truck ran for 30min. ECM failure!? ECM replaced butneeded programmed. Dealership tried to program but continous failures (notenough power to ECM). 1 week later no one could figure it out so I had it towedhome. Won't start, no fuel pressure and lift pump does not turnon. No power to VP44 pin#7, constant 12V on Blue with red tracer(Lift Pump feed). There is 12V to the (2) red/white wires to ECM. Replaced the fuel system relay but only see 8V at the oneside of the relay (coil side). Relay does not switch. Found that ground from ECM/VP44 wire harness was showing 20ohms. I repaired a the ground connection to the passenger sidebattery. Now showing 9 ohms at ECM plug and VP44 plug. I read "bluechip diesel's" diagnostic page. Madegood sense but I could not make heads or tails of my lack of power. Is there anyone who can make sense of this mess? Truck isdead and life sucks riding the motorcycle in the rain.
