93 Jeep Grand Cherokee Cranks, But No Start
 

My 1993 Jeep Grand Cherokee recently started having starting issues. At
first it would start after 2-3 tries, but now it continually takes
longer and longer to get it to turn over. First I thought it was the
battery (weak or being drained), but after a full recharge and
replacment, the problem persists. Cables appear fine. Jump-starting
will help if the battery is weak, but it still takes multiple tries to
get it to turn over. This morning, it took 20 minutes and at least 25
tries to get it to go from cranking to actually starting. Sometimes
during cranking the security light flashes on the dash. Sometimes you
hear what sounds like a solenoid(?) clicking when you turn the
ignition. Often if you keep turning the ignition on and off until you
hear the fuel pump priming(?), then on the next crank attempt, it
starts, but not consistantly. I'm suspicious of a short somewhere. Fuel
solenoid? Security system? Anyone have any ideas or suggestions?

Because the idiot light comes on, I would be suspecting the alarm first.

Second I would be suspecting the body ground is dirty or has failed
because of the 'sometimes' factor. The body can steal grounds through
things like the gas pedal cable and brake pedal, but it is not
consistent.

Some 4.0 engines have a mesh strap from the rear of the head to the
firewall and/or from the engine to the frame across an engine mount, but
some Jeeps use a negative cable from the battery to the fender for a
ground.

You have ten years, a hundred thousand miles, you need a new fuel
pump.

I second that option.
