I used to prime my fuel pump for 3 seconds, or 3 "beeps" before I would attempt to crank over the 4.0L. It would start within 1/2 second.
One day I was in a rush to do somethings and forgot to prime the pump. It took about 5 seconds of cranking to finally turn over the engine.
Ever since then even while priming the fuel pump the engine will randomly start quick or slow. I have noticed that sometimes the longer the engine sits cold, the longer it takes to start. But other times it can sit until it's completey cold and start right up.
Any suggestions as to what the problem might be?
