Engine Mechanical problem
1999 Jeep Grand Cherokee 6 cyl Four Wheel Drive Automatic 135000 miles
Hey guys, pulled into the parking lot of grocery store, and when we came out, the car won't start. It will crank, but won't turn over. Tried spraying starter fluid, but there doesn't seem to be a flame. Mechanic says it is the computer, but seems awfully strange for it to have just happened " over night". Wondering if there is a fix that won't cost a grand to get this thing running. Thanks!
Hi rpapon, Welcome to 2carpros and TY for the donation
They all say that about the computer there's more money in it-when the fix relates to an ignition problem-No spark-when you are using the starter fluid
Do below to determine if its a fuel or spark porblem
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
