1999 JEEP GRAND CHEROKEE NOW LEAKING GaS AT TOP OF GAS TANK AFTER A FUEL PUMP BEING PUT IN

My first problem was after having my brake pads changed, I constantly hear a sound which sounds like air... Several months later, my fans to my heater stopped working but worked on high... I'd been driving with those issues for about 8 months. Then while I was sitting idle one day I noticed my battery gauge kept dropping and then I wasn't getting any heat... I had it checked and the mechanic stated their was a small hole in the radiator pipe and that is what caused it to leak antifreeze... He repaired it and put in anti-freeze... The next day I noticed the engine coolant fan was remaining on even after the car was turned off.... The next day we had below zero weather...1999 JEEP GRAND CHEROKEE BATTERY WENT DEAD DURING INCLEMENT WEATHER.. Gave the car a jump and it started immediately,,, I let it run for about 10 minutes and went into the house. When I came out to crank the car again it would not crank... And the alarm system would not go off... Finally got the alarm to start working properly... I think it ran out of gas at one point while trying to get it started... I put in 7 galloons of gas and it still did not start... The mechanic stated, it needed a fuel pump... Mechanic put in a brand new fuel pump and filter now the truck is leaking gas from the top of the gas tank... The truck was running perfect and then all of sudden.. It won't start.. All the lights on the dash works, the radio, horn, etc... It turns over but it will not crank.. I need help... I have already put over $500 into vehicle.. HHEEELLLPPP!

If it's the CAT you should be able to notice this while driving as driving with blocked or broken CAT usually feels lack your lacking a little power, like the car is slower than normal, also if you hold your foot on the accelerator at the same place you may notice what almost feels like air bubbles in the fuel line kinda feel, little jerks as your driving along as if the car does not like being sat at set revs, cars with the CAT on it's way out usually like to either be accelerating or decelerating not sitting at the same revs as you get that jerky feeling, thats one way to tell... If it is blocked up it can stall by blocking the air coming out of the exhaust, the other issue maybe the backbox on the exhaust could need replacing, similar symptoms as i mentioned before as it's all in the same pipe doing similar thing to the air. My garage once drilled a hole into the backbox and it was like magic and the car felt like new again!! which loads more power, the back box needed replacing of course along with the cat.
Aside from the above could it just be your tick over is set too low? just an idea... You will usually be able to tell if it's the cat from driving it, you will notice a difference in the cars performance, it will feel very restricted when you put your foot down like the old cars with the distributors on them when the timing was out, it feels like that! hope that might help a little but im not a certifed mechanic!

SOURCE: 2004 Jeep Grand Cherokee temp gauge high when heat is on

If your "check engine" light is turn on, I suggest scanned the PCM to know exactly what fault code is stored there. Additionally, could be some problem with the "temp sending unit".

Keep us updated.

Were is the fuel pump on a 99 jeep grand cherokee, and is it hard to replace?


You will not like my answer.

The fuel pump is inside the gas tank.

You will need to drain the tank and drop the tank to gain access to the fuel pump via the top of the gas tank.

Mark sure your new fuel pump has a new screen/sock filter.

Change filter filter at the same time!

1999 Jeep Grand Cherokee Died while driving home


check the fuel pump fuse/relay, could be just bad enough to cause an intermittent start/no start. and check fuel pressure,spark and the crank position sensor.

Changing the gas tank on a 1993 jeep grand cherokee


Make sure you use lots of wd40 or other solvent on strap bolts. Use a flashlight not a droplight while working. Keep all open flame sources and sparks (even electric drills etc) away from work area.
make sure the tank is low on fuel...gasoline weighs over 7lbs per gallon! have something to put fuel in to drain tank further after removal. An empty tank is a bomb unless it is left open and allowed to vent out for a few days in a safe place outdoors. If you intend to re-use it, wash it out with soap and water then to store, dry it out, coat inside with oil. If transferring fuel pump, be careful not to bend float arm or gas gauge will not be accurate.
Other than that it's a big box with some straps holding it in. good luck
