My Jeep cranks and turns over but will not start. Compression is 50 lbs. at valve. Gas flow is more than adequate - was going to replace gas filter but there is lots of gas at the electronic ignition.

Sometimes the engine will start and run fine, sometimes it won't start after it is shut off.

Can there be an intermittent problem before the gas pump fails? What else should I be looking at?

Your help is greatly appreciated! Donna Forhecz

My Jeep cranks and turns over but will not start. Do below and get back with some results asap

Disconnect a sparkplug wire or 2 and ground it to the engine -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,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it
