04 grand cherokee laredo hard time starting
Just bought my jeep a week ago. Last night when I went to start it, it took a few times before the engine turned over. It turned over after a few attempts, and kind of sputtered while sitting at a red light. It didn't die but I thought it might. The next morning I had a hard time turning the engine over it took a few attempts. It did and I went to work. After work the dame thing hard time turning the engine over. After work I wanted to Fo to the store and again the engine had a hard time starting up, but on the way to the store the check engine light cane in and stayed on. Git hone from the store and turned off the engine, it started up normally. It seems as though the longer it sits the harder it is to restart. I'm wondering if the check engine light and the problem starting are related, any thoughts?
Dirty idle air control valve or vacuum leak maybe? It appears that your jeep doesn't have an egr valve, so I it couldn't be stuck open. Using a scan tool, check your map sensor pressure/vaccum. Also with a scan tool, what are your short and long term fuel trim numbers? Is the engine running rich or lean while idling?
No, pressing the gas pedal did not help. Got it back from mechanic apx 30 hours ago, been driving it now, and its fine. Mechanic said the fuel pressure was low. He replaced the fuel filter which has a sensor or regulator on it, and all is well again. So not sure if there were two problems or one problem. But both parts were replaced and my jeep is back to normal, only cost $240.00
