Trying to find were the safety fuel cut off switch is located on a 1987 grand wagoner


I have the 87 cherokee and I don't think it has the "tip over" fuel cut off safety switch. If you are not getting any fuel the fuel pump (its in the fuel tank) has either lost power or stopped working. They used a couple of different styles so don't buy one untill you have pulled the old one out. also you can check for voltage on the wires that feed the fuel pump. If you have voltage but are not getting any gas flow then the pump is not working.

Where is the fuel pump reset button the van will turn but acting like no fuel


There is not an fuel pump reset button. There is however an Automatic Shutdown Relay that acts as a fuel pump shutdown. On the 1998 Model: It should be located in the Junction Box located under the leftside of the dashboard There should be a cover over the top of the Junction Box. On the backside of that cover is the identification and location of the Relays and Fuses. If there is no cover, your Owner's Manual should have a schematic identifying the location, position, and type of Relay and Fuses. There should be additional Fuses involving the Fuel Pump. Make sure you not only check the Relay and Fuses to see if they are good, also check with a Voltmeter to check for voltage, with the Key in the "ON" (not start) Position; it should read approximately 12v,

With approx 12v present at the Relay and Fuses, one quick way to determine if there is Voltage to the Fuel Pump:
1) With a Partner behind the wheel. Take the Gas Cap off and place your ear up close to the opening of the Gas Filler Tube. Have your Partner turn the Key to the "ON" (not Start) Position. You should be listening for a humming sound (for 2-3 seconds)meaning the Fuel Pump is getting power (volts).
2) If there is no "humming" or you are not sure, get underneath the Van next to the Gas Tank and have your Partner do it again. Listen for a humming.
3) If there is definitely no humming present with good fuses, relays and voltage, then most likely the Fuel Pump is bad.
4) However, a lot of Fuel Pumps have been replaced only to find out the Pump was good, but the electrical wiring harness was bad and the real culprit.
5) You will have to slightly lower the Fuel Tank to gain access to this electrical connection.
6) After you disconnect the electrical connection, using the Voltmeter check for approximately 12v coming from the Wiring Harness/Connector.
7) Inspect the Wiring Harness/Cnnections for any signs of burns, melting, or shorting. Repair this wiring harness before deciding to replace the fuel pump needlessly.
8) After repairing the Wiring Harness/Connection: Replug it back in and recheck the Fuel Pump one last time.
9) If still no "humming" the Fuel Pump needs to be replaced.

If there is humming from the Fuel Pump, then there are four possible problems.
a) Fuel Filter (when was the last time it was replaced?) It could be clogged, prohobiting fuel flow.
b) Fuel Regulator. Located on the Fuel Rail where the Fuel Injectors are. If there is a presence of Gas in the Vacuum line (the only rubber line on the Fuel Regulator) attached to the Regulator, then the Diaphram of the Fuel Regulator is broke and Gas is not reaching the Fuel Injectors. Instead it is being dumped into the Intake. Replace the Regulator.
c) Fuel Injector Circuitry problem. Using an Auto Stethoscope: Place the Stethoscope end in each individual Fuel Injector. Have your Partner attempt to start the Van. If there is no evident and rythmic "clicking" (fuel injector's gate opening and closing) then the Fuel Injector is faulty or the electrical connection is faulty. To check to find out which is faulty, switch Fuel Injectors (one clicking with one not clicking) and recheck for the clicking.
d) Clogged Fuel Injectors. With the Fuel Rail (with the Fuel Injectors) removed out of the engine. Place clear Plastic tubing over the nozzle ends of all exposed Injectors. With a Partner Starting the Engine, look for
(1) Fuel Flow (presence).
(2) Fuel Spray (pressure).

I am having a problem with my 05 jeep cutting off at slow speeds and jerking like its isnt getting any gas.. could you please help


A new fuel filter should be tried along with a bottle of fuel injector cleaner/water-in-the-gas remover. Then check for low fuel pressure at the fuel test port (a tire valve looking device) that is located on the fuel rail which runs over the injectors--the pressure should be in the 40 to 50 PSI range. If very low, try a new fuel pump.

My gas mileage went from 18 to 13mpg for no apparent reason. No indicator lights or computer information. I had the plugs changed and still the same. Suggestions?


Look at the gas pump and see what additives they are putting in the gas. They cut down the gas with 10% of something for the winter and a lot of cars don't like the cut although it will seem to run fine. Add an additive to clean your injectors also-the good stuff. Hope this helps. One other thing check your air filter. Restriction there will cut your mileage.
