Hi all -
I have a 1991 Jeep Cherokee Laredo with the in-line 6 and auto-transmission. I have been fighting a hard starting problem as follows. In the morning from a cold start it will take up to 10 seconds to start. And then it will run very rough until it warms a bit. Subsequent restarts then take less than 2 seconds, and I don't even need to step on the gas. When it starts hard, I have tried the trick of turning the key on and off a few times to let the fuel pressure come up. This seems to make it worse, if anything. I have replaced the plugs, wires, rotor, cap, air filter and CCV tubing (no PCV valve on this model). There is no leaking around the injectors, pressure regulator or fuel lines that I can see.
candidate is the CPS. I've read that this gadget is not easy to get at. So, my question is, is this something that a DIY'er can tackle without screwing things up? Where exactly is it located? Do I need anything other than basic handtools to get it out and get a new one in? Any other words of advice?
Thanks for all your help, Bud
