1998 jeep grand Cherokee 5.2. problem started couple of weeks ago. when you turn the key, cannot hear fuel pump
engage and preasure the system. Tank is full. If you let sit in the sun and warm, eventually an hour or so the fuel pump would engage. problem gradually worsened over a couple of days until the fuel pump will not engage at all. Has a new control module and a new key assembly installed since the problem started. swapped around the relays and the fuses made no difference
JA: Can you turn the steering wheel at all? And what about the key? Is it worn or damaged?
Customer: Brand new key and switch and the steering wheel will turn
JA: Are you fixing your Grand Cherokee yourself? What have you tried so far?
Customer: Yes, and just the above.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Had a tune up a couple of months a go with new cap, wires, plugs and crank sensor
