My 2004 Grand Cherokee has a long cranking time..
My Grand, cranks for a very long time . Finally , if you give gas it will start. Chrysler paid to have a full diagnostics run on it my Jeep dealer still could not find the problem. I told the person at Chrysler that it was kind of strange that we have the only 3 Jeeps that do this as they said they've never heard of this problem. After the diagnostics were completed they said that the only thing that they could "think" of was it needed a new throttle body. I have not gotten one yet (mechanic said I could get one at a salvage yard for about 50 bucks and he told me what to clean it with). I haven't tried that yet. Has anyone else had this problem? If so, what was the remedy? Thanks
Not on a Jeep specifically but this is fairly common on GMs. Sounds like the fuel system is losing pressure. My '03 S-10 Pick Up does the same thing if I don't "cycle" the ignition key before starting it. There's a check valve in the fuel system that prevents the gasoline from draining back into the gas tank after you shut off the engine. On a GM it's part of the fuel pump assembly. It may be in line on your Jeep. Try this. Turn on the ignition but don't try to start it. Count to 5 and then turn off the ignition. Repeat. Now try to start it. If it fires right up that confirms the fuel system is losing pressure. You'll need to find out about that check valve. HTH. -Jim
That's what the Jeep dealership thought too. They actually had me come back and look at the fuel pressure gauge as they were running the test. It was fine. They put a new check valve on it. It starts great when it's cold (I mean the weather) but once it's been driven and has warmed up it cranks and cranks. I tried what you said (on the 92,2001 and 2004) and it didn't make any difference. I really appreciate your response tho. Thank you
You're welcome. Sorry I couldn't be of help! - Jim
