the pressure is regulated in the pump on these
the fuel rail has no control over how much fuel the injectors pulse out. it's all controlled by the pcm. i would start by checking whether the injectors are actually pulsing or are stuck open.
'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
Tested the pass side bank, signal is pulsed , found that the wire harness going to computer (looks like pcm mounted on firewall on pass side) has no clips and was sorta loose. I'm going to stuff a rag back in next to it ( for now) and put the plugs back in n give it a go
I just unplugged all the pass side inj and cranked it. I put a pillowcase over plug holes to see if fuel is still coming out, and it is.
Gonna warm up a bit then unplug fuel pump relay. Crank it till no fuel comes out. Heat the injectors with a hair dryer (wife is gonna love that) then plug relay in and see what happens when I crank it.
It all started the day after I dumped inj cleaner in, and temps went below freezing. Hasn't warmed up since. I am wondering if pass side inj are bad or frozen
I've had the charger on it. I put it on 50amp when cranking too. I'm hopping they are just frozen. Was thinking of tryn the 94 injectors, different part number, but if they fit, it might give me an idea troubleshooting
