I swapped a 2006 5.7 into a 54 dodge truck. have the entire car I've been using the parts off of. Been through the pin outs and all the wiring for weeks on end. a virtual book of information. I have searched every way I can think of to find any related info on here as well.. I have a MMX made cam and MDS shut off, I have it mated to a T56 6 speed trans so no TCM to worry about. Read through and searched to my wits end on how to get it to start. ASD relays are functional, Data port is working now ( found that it needed a 100 ohm resistor in place! Thanks for that info guys!), Fuel pump relay is active and running fuel into the rails. Home made fender headers with the front O2.s installed etc....I even set the starter relay back into to system instead of stand alone. If I lift the rails and add fuel into the injector ports the truck starts so the coils/ignition work.
The problem I have is that I cant get the injectors to pulse. Have the power side tested and its there. On the scanner I get no injector pulse width, no fuel trims and the fuel system status reads OL not ready. DTC comes up with an implausible fuel signal . I shut off anything I could find in the editor for the Bank 2 O2's and fuel signal search. Hoping it would not look for fuel as a fault. I do not understand the tuner program to change values so i will have it tuned remotely after i can get it running . multiple tuning software that I bought for each vehicle i have and still cant get my brain around the values.
Does this seem like a tuning issue with the fuel or is there a way to find if I fried the PCM? The car drove into the garage when I started the project so I know it was good at one time.
