1. '96 Cherokee Cold Temp Start Issue

    This winter, my 1996 Cherokee Sport developed a cold temperature start problem. If overnight temps are below 50 degrees or so, the engine cranks just fine but without firing. If I pump the accelerator, while doing short cranking bursts, it eventually roars to life. Of course being fuel injected, I have no idea if the pedal pumping is really affecting the start. Sometimes after this type of start, the engine will not idle until it warms up. When temps are warmer, the cold engine always starts right up like normal. No vacuum leaks are apparent, and the Manifold Air Temp Sensor seem to check out as OK. Sound familiar to anyone?

    Check fuel pressure key on and off and while it is running. Should be constant.

    Check spark to the plugs.
