Not getting any fuel
Asked by Jmpresley1 Nov 10, 2018 at 06:19 PM about the 1999 Jeep Cherokee Sport 4-Door 4WD
Question type: Maintenance & Repair
My 99 Cherokee will start right up if I haven't driven
it for several hours but if I run errands and then
stop somewhere turn off car and go to leave again
it won't start. Acts like it's not getting fuel. If I jump
on the bumper like I'm shaking up the fuel it will
start. Any idea what's going on? Fuel pump is
couple years old.

If you think it's a fuel problem, hook up some pressure gauges to the Schrader valve fitting on the fuel rail under the hood. Looking for 60psi I believe. If low, check/replace fuel filter which also contains your fuel pressure regulator. Scan for fault codes by turning key Off to On three times quickly without starting engine. Stop at "On". Codes will display at odometer screen. It will show "done" when done. Frequent problem..no spark...is crank shaft position sensor....code #P0320.
Before I bought any parts I would do this very simple thing but very important thing 1 make sure you have a good strong battery and it is connected well to check on your grounds to the firewall in inside fender I think you may have about four or five of them and if possible check your ground wire from Battery to frame.... and when I say check them I mean I do them and clean them make sure the surface you're connecting them to is clean. Every ground has to go back to the battery what if you have one this night the brain won't know how to direct the current hope this helps it doesn't cost anything and relatively easy to do
I have a 96 jeep Cherokee sport it will turn over but won't start. After replacing coil, distributor, found out have no fuel pressure at the fuel rail. Put new pump in the tank still won't start so started messing with fuses under the hood in the fuse panel. If I use a jumper wire fuel pump works and my jeep starts. So bought new relays replaced them but will only start with the jumper wire. Any ideas
