    Is there fuel pressure at the rail? do you have spark at the coil, at the plugs? what have you checked and why did you change pump? did you check fuel filter & relay?

Hopefully this will answer your question.

The redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor. The structure was stiffened by PorscheEngineering for sharper steering and lighter weight. The spare tire wasrelocated from the side of the cargo compartment to under the floor togreat relief of owners. The two heavy pushrod V8 engines were replaced by chrysler's first clean sheet V8 since the 60's (SOHC aluminium heads, plastic intake), Chrysler's then-new PowerTech. Although this engine produced less torquethan both previous V8s, it was lighter and got much better fuel economyand provided similar on road performance figures (the 23 gallon fueltank was replaced with one of a 20.5 gallon capacity). The Inline 6engine was also updated in 1999. 10 horsepower (7.5 kW) was added byredesigning the intake manifold. The manual transmission was dropped with this model.
While other Jeep vehicles used the Mopar 5 x 4.5 bolt circle, thiswas the first Jeep following the 1987 Chrysler buyout to receive awider bolt pattern — 5 x 5. The 5 x 5 bolt pattern (also 5 x 127 mm),although common to GM rear wheel drive vehicles and light dutytrucks/vans, has spread beyond its use with GM (and Ford with their 1973 to 1978 LTDs and Lincolns). Chrysler first used the 5 x 5 pattern on full-size half-ton Dodge Ram pickups and Dodge Ramcharger SUVs in 1986.
A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive II.With three viscous clutches, it was one of only a few four wheel drivesystems at the time with triple locking differentals, joining thecontemporary Mercedes Gelandewagen, Mercedes Unimog and Magna SteyrPinzgauer, and the only one of the four with fully automatic operation,although the axle differentials could not be manually locked like inthe other three vehicles.
The 45RFE and 545RFE automatic transmission in the WJ was notable. It included three planetary gearsets rather than the two normally used in a four-speed automatic. Thisgave it six theoretical speeds, and it would have been the firstsix-speed transmission ever produced in volume, but it was programmedto only use five of these ratios. Four were used for upshifts, with adifferent second gear for downshifts. Although five of the six ratioswere used, Chrysler decided to call it a "4-speed automatic". In 2001,the programming was changed to make use of all six ratios. Rather thanhave six forward gears, the transmission was programmed to act as afive-speed with the alternate second gear for downshifts. The RPM at70 miles per hour (110 km/h) on a 545RFE is 2000 rpm, 200 rpm less thanthe 45RFE programming. 1999 and 2000 model year WJ owners can havetheir 45RFE transmission's programming flashed to enable the extra gearas both transmissions are physically the same. The 42RE 4-speedautomatic remained the transmission for the Inline 6 engine. It was notchanged from the previous model Grand Cherokee's.

Check the Trans fluid level with it running and at operating temperature. Jeep NAG1 transmissions are known to have the input electric seal leak trans fluid. Not an exspensive fix add Mopar ATF4 and then relace the guild seal.

We have a 1995 jeep grand cherokee limited 4 wheel drive. how do you know when the fuel pump is going bad?


you will notice that your vehicle acts like it is starving for fuel, and sometimes , the engine will even die, and then start back up, a lot of fuel pumps can be saved by people not driving their vehicles with a 1/4 or less amount of gas in the tank, because when the the tank gets very low, the fuel pump has to work harder to pump the gas, and even overheats when trying to pump the low amount of gas to the engine therefore resulting in the fuel pump going out.

The first years of that body shape, like the 93 Grand Cherokee, had ecu computer problems. Next time it won't start, check to see if the check engine light does lights up on the dash, when you turn the ignition on, before cranking. If it does not, the fuel pump will not kick on, until that check engine light does come on. It's referred to as the delayed check engine light problem, on early to mid 90's Jeeps. If you find out that is indeed the problem, you can have the ecu computer repaired.

Fuel gauge


you either have a bad sending unit, which iit is in the fuel pump assembly in the tank or a hole in the float and it fills with gas and sinks, which it's also on the fuel pump assembly in the tank or a bad fuel gauge in the instrument cluster. it's more than likely a sending unit problem, jeeps are bad about the sending unit to quit working
