There is no automatic fuel shut off valve on Jeep's ! A electronic control module Controls the fuel pump . (TIPM ) totally intergrated power module ! Go to http://bbbind.com/free_tsb.html free wiring diagrams ! Your best bet would be to take your vehicle to a qualified repair shop .
There is a fuel pump reset switch under the dash near the lower heat ducts at the floor.i think on the drivers side but it has been a long time since i done this.
Check Fuel Pressure. First turn key to on position (without starting) and listen for the fuel pump motor. If no motor sound, your fuel pump is not working. Check fuel pump fuse and relay. If fuel pump works, check for pressure at the fuel rail (schrader valve on fuel rail for pressure testing). If no pressure, or not enough, fuel filter might be clogged or fuel pressure regulator may not be working properly. IF fuel is not the problem, start checking electrical, such as ignition control and proper spark to plugs.
You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?
had a 2000 blazer 4.3 wouldnt start in really cold enviroment..... ended up being the FUEL PUMP RELAY.... it still running good... bout every ther day or so... but it acted like your truck
i would suggest checking to see if you are getting fuel by disconnecting the fuel line at the fuel rail and turn key if no fuel then its either fuel pump or fuel filter. if you get fuel then it would be the spark
I'm sorry, but I'm a bit confused regarding your statement where you said, "I drove it without a air filter for 4 days the put in a new one but it still wont start." Please clarify. Thank you, jetski224
