hi , do you think if I replace crank sensor will solve the problem ,my jeep .... Where's the crankshaft located in 99 jeep grand Cherokee laredo .
Check for spark at plugs, fuel pressure key on/engine off, and last compression test. If no spark, check all fuses then ignition module/coil. If no fuel pressure, check fuses, relay and listen for pump noise for two seconds or so after key on. If low compression, check timing belt (if any).
If it didn't come with fog lights, it may also have not included a fog light relay and/or fuse. Check the owner's manual for fuse and relay locations, and then check if the necessary parts are there.
Check the crankshaft position sensor, i have repaired 3 Jeeps (after the owner spent a lot of time and money replacing fuel pumps,TPS, and many other items) then got frustrated, brought it to me and within an hour it was running fine with a new CPS
Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)
