Thanks hey you. I bought electronic cleaner and sprayed heavily on all connections and doubled up on grounds cleaning paint off them. The other thing I should mention is I watched a YouTube video before I wired in the extra injectors and they didn't change the PCM when doing the same swap. Oh also there are no oxygen sensors on the truck or exhaust. I just want to try all I can before buying a computer. Will a junkyard one work off of a truck with a V8 ? The NO BUS condition is still there , the engine turns over but there is no spark or sound of fuel pump. Any more suggestions would be greatly appreciated.

 

What are you working on??

 

1999 Ram 1500 I installed a 5.2 from a 1997 Cherokee

 

You need to have the PCM flashed for the V-8. Of course, the no bus error is going to complicate that. May have a pinched wire somewhere, or, a bad sensor. Crank sensor comes immediately to mind, as you swapped engines.....

 

im hoping i am allowed to post this here as i am desperatlly in need of some guidance, i also have the no bus issue, i have replaced ignition switch, PCM, ground and posotive cables, connectors to battery, battery, checked all relays and fuses , tested all grounds etc.... truck starts and runs fine but i have no break lights ( tail lights do work) no turn signals, no dash activity except foe all warning lights, no wipers but , after driving it for about 15 mins everything comes on and works and will continue to do so untill i park and shut it off for more that half hour. then its same old thing once stasrting it again, no activity for the first 15 bmins or so....i had alternator test it passed also.. 2003 dodge ram 1500 slt 4x4 5.9L magnum.. PLEASE, i am at a lose..yes i did hard reset on it and relearned the computer. also when i hook to scanner it doesnt even read truck at all, i did the c code thing on truckand got several codes but they all pretty much point towards everything ive fixed. bought PCM from reputable source and it was programed for my specific vehicle and VIN.any and all help will be appreciated as my mother has stage 4 cancer and i take care of her and its my only vehicle and weith this issue i cant drive at night cause break lights or in rain cause no wipers etc...thamks again
