93 Grand Cherokee Limited
 

Hi folks. My husband has the above vehicle and is having some problems.
The car has 135,000 miles.

Over the years he's had issues of stalling or not starting. In March we
were in Colorado, driving down a gravel road at about 11,000 feet and it
just died. After getting it towed into town (which was an adventure in
itself) we had the fuel pump replaced. Even after this, we had to hit the
tank with a 3 lb rubber hammer to get it to start for a few days.
Since then, it has not stalled out while driving but at least once a week it
will not start. It cranks well, will sputter for about 10 seconds and then
die.
This has been replaced: Coil, Fuel Pump and Camshaft Sensor. If he can let
the jeep sit for more than 4 hours it will usually start, it's on shorter
jaunts that it will not start again. If he calls a mechanic, it will
usually start by the time he gets there.
He took it to a dealer and had them hook it up to a diagnostic
computer....Everything tested out fine. The mechanic told him that he did
have a cracked rear manifold which could be making the fule mixture too
rich.

any suggestions on what to try next would be appreciated.

Checked the fuel filter or done a leak-down check on
the fuel rail. Should be 32psi and stay close for at least
30 min after the engine is shut off.

What your describing could be a bad pressure regulator on the
fuel rail, a bad valve in the pump, or a terribly clogged fuel
filter.

Have you pulled the distributor and checked if it was full of oil?
If it looks like mine did you need to replace it.

Pull the codes and see what it says.

FWIW, the fuel system doesn't set any codes. 12 and 55 are "normal"

As for the cracked manifold.

If you had to hit the tank, something wasn't replaced properly or
sealed. Heck, it could even be a bad connection.

I'd replace the fuel filter if it hasn't been replaced before.
