So my buddy just got a 00 Cherokee n took it wheeling. One time it was hard to start. Later on nothing. Getting fuel and spark but no start. Computer? Cps? Any tips

Gee oh Dee

If your getting fuel and spark for sure it's timing.

How did you confirm fuel and spark?

tj v. xj

Changed plugs. Ground againts block all sparking good. Tested compretion n everything. Won't even run off eather

Gee oh Dee

How'd you test for good fuel pressure?

tj v. xj

Idk how he did. Had a local guy that works at a dealer check it out. Few blown fuses in cab. Any go.to ignition?

What's a way to test injecyor pressure?

XJ BoSS

A pressure tester with the adapter for the fuel rail

tj v. xj

Just pulled fuel rail. All injectors firing good

Gee oh Dee

May be bad coil packs.

DId you say youve got several blown fuses? I'd definitely check into that however unrelated it may be. Throw up what numbers they are, may be a simple fix there. Checked the CPS? look and see if its caked with mud, if so then clean it off real good and try again. Also check the camshaft position sensor, it can throw the timing off as well. And dont dish out the coil packs so quickly.. You can be getting spark but not sufficient enough spark for ignition.

Replaced all fuses n entire jeep. Getting good spark. Changing both censors tommorow.
