The XJ's electric fuel pump lives inside the tank. When it dies you get a no-start; when it's dying you get hot-restart problems and stalling under load. Confirm with a fuel pressure test, then drop the tank to replace it. Plan a Saturday — a quarter of that is fighting rusted tank straps.
A failing fuel pump is one of the most common reasons an XJ won't start. The pump is fully submerged in the tank — fuel cools and lubricates the motor, which is why running the tank to empty repeatedly is the single fastest way to kill one. By the time the pump can't build pressure, it's usually been showing symptoms for weeks: a stumble when accelerating from a stop, a longer-than-normal crank after the engine has heat-soaked, or a momentary loss of power on a hot day when the in-tank pump can't keep up with demand.
Three things make this job year-specific. First, the fuel pressure target changes by era — 31 psi on Renix (1987-1990), 39 psi on early HO (1991-1995), and 49 psi on the returnless 1997-2001 system. Second, the part itself changes — the Renix and early HO use a pump-only assembly with a separate sender, while 1997-2001 trucks use an integrated module that combines pump, filter sock, pressure regulator, and fuel level sender into one unit you swap whole. Third, 1996 is a transitional year that splits the difference and uses a one-year-only setup; double-check the part number before ordering. The procedure to drop the tank is essentially identical across all years.
Before you do any of this, **test fuel pressure first**. A fuel pump module costs $100-$250 and the labor is a half-day. A bad coil, a failed crank position sensor, a clogged sock filter inside the tank, or a failed fuel pressure regulator can all mimic a dead pump. The pressure test takes ten minutes and tells you exactly what's wrong.
Why it works
Fixes hard starts, no-starts, and hot-restart problems where the pump is genuinely the cause.
A modern Bosch or Carter module on a 1997-2001 truck restores OE-spec pressure and tends to outlast the original — early modules failed at 80-120k miles, and the current OE-equivalent Bosch unit (67410) is the most-recommended replacement on Cherokee Forum and NAXJA.
This is also the moment to fix every adjacent thing the tank drop blocks access to: rusted tank straps (Crown 52000513), a corroded fuel filler neck, rotten EVAP hoses, or a worn rear-of-tank skid plate. Doing them now is free labor — you have the tank out anyway. Skipping them means you're back here in a year.
An in-tank pressure gauge reading confirms the fix end-to-end. If pressure is in spec at the rail after the install, you know the pump, the filter sock, and the regulator are all working — which is more than a starts-and-runs test tells you.
Trade-offs
The tank is messy and heavy enough to be awkward overhead. Even at a quarter-full it's 30-35 pounds of liquid sloshing around — drop it on a jack, not your face.
The strap bolts are nearly always seized on a 20+ year old truck. Plan for snapped bolts and have a tap and a fresh strap kit ready before you start. Trying to wing it costs you the weekend.
Brand matters more than price. Bosch (67410) and Carter (P75040M) are the safe choices for 1997-2001. Airtex modules have a reputation for premature failure on XJ forums, and generic "BlackHorse" or no-name units off Amazon routinely fail within months. Spend the extra $60 — you don't want to drop this tank twice.
If the pump was the wrong diagnosis, you've wasted a day. The pressure test in step 2 is what tells you whether the pump is actually bad. Skipping it is the single most common reason DIYers replace a pump and still don't have a running truck.
The 1996 transitional system is a parts-lookup hazard. The tank, pump, and regulator are unique to that one year and not interchangeable with 1995 or 1997 hardware. Always order by VIN, not by "1994-2001 Cherokee."
