'04 Rubicon Only Starts on Second Try
Hi all. My wife's '04 Rubicon only starts on the second try. I've been snooping around on this and other forums for some time trying to figure out the problem. Thus far I have cleaned the TB, replaced the Fuel Pressure Regulator, the IAC Motor, and the CKP Sensor. No luck.
Initially the problem manifested itself as long-ish crank times before starting (3-4 sec). It has since progressed to cranking for as long as you're turning the key and still not starting. As soon as you let off and try again, it starts right up.
I haven't tested the fuel pressure (no test port), but I have tried the vise grip trick with no luck. Leaving the key on for a while and then trying to start does not help either. Theres no gas in the oil--injectors seem fine. So, I don't think it's a fuel problem.
I did get a IAC malfunction fault code, but that was only after I cleaned it and did not get the plug back on completely. Replaced the IAC just for fun. No luck, but no codes.
While I was spending money and reading forums replaced the CKP and the spark plugs as well. After replacing all that, the jeep started the first time right away....once. No luck on subsequent tries.
I have checked all the wires and plugs including the CPS and TPS. God battery too. Nothing seems to be working.
HELP I AM PULLING MY HAIR OUT! At this point in time it's about pride...I am determined to fix this thing myself!
