Chasing hard starting issue on 96 XJ 4.0 2wd auto with in-tank fuel pressure regulator. Takes multiple cranks, hot or cold. Have already....
Replaced fuel pump and pressure regulator
Replaced tps
Replaced IAC
Cleaned throttle body
Battery, dist. cap, rotor, plugs and wires all replaced 10 months ago.
Ordered an intake air temp. sensor to try next. No CEL during all of this. Just hard starting.
From what I’ve read here, another possible culprit is the CPS. But I have NO other issues... once she starts, she runs and idles smooth and strong. Is it possible for a faulty CPS to cause hard starting and no other symptoms?
