Question about Jeep Grand Cherokee

1 Answer

I drove my Jeep to school and after class it wouldn't start. It cranks really good but sounds like it's not getting fuel. How can I check to see if the fuel sending unit in the tank is working or check the relay?

Get somone to turn the key to the on position while you listen for the pump in the fuel tank usualy a whiz or wineing sound if you hear it the you good if you dont hear it when turning the key to the on off on position "the positoin before you crank the engine" then try hitting the tank with a stick or hammer a few times it could be stuck. if this works then park it when you get home, until you get a new pump.
you can check the pump relay usually under the hood in a black box marked as fues or somting like that the relays are marked on the bottom of the lid. if you dont hear clicking with key to on off position then try switch aound with a similar relay in the same junction box

My 1995 jeep grand cherokee Laredo won't start, or


You might not believe this, but check your battery. Some of these vehicles have cut-outs when the battery level goes below a preset amount.
I work on Ford brands and on them, a low battery level will even disconnect the Alternator circuit and mess with the starter. Some even act up when the battery slightly dips below 12 volts.

Your antitheft can make your starter cut out. And If you think about it, all of the measurements to make the engine run are based on feedback of voltage and amperage. This is how the engine management system adjusts. If your prime source of power is low, then all of the following electrical readings will be low. Some may be too low to work.

Your fuelpump will hold pressure in a closed system for hours. The fuel pressure regulator will command the fuelpump to stop working if the fuel pressure is at maximum. Without responses from the other components and after satisfactory pressure, the fuelpump will turn off.

98 Ford F150 w/4.6l Wont start. Hear fuel pump click. Have pressure on fuel rail. Pulled #1 plug from head and plugged back into wire. Grounded plug and cranked. No spark. Changed wires 4 and 7 four days...


have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy
