Haven't found any definite answers on this one, so I'll start a new thread.
Trying to chase down a no-run issue on my step-dads 96' XJ.
4.0
Automatic
apparently his fuel pump went out on it, and him and a backyard mechanic buddy changed it, very shortly after it wouldnt run anymore. he'slet it sit for probably 4-5 months now and finally asked me to fix it.
It appears to actually fire over but the second you let off the key it dies, not stalls out but just flat dies.
I figured it was a bad pump as thats when it started having issues. I show ~45PSI at the rail, but when it is firing over it seems to have spikes up to ~60PSI. I thought maybe a blocked filter but its just odd that it will not run at all, just dies hard when you let off the key.
any ideas?
