this problem started last year with intermit no start.i could pull the plugs dump some gas in the cylinders then it would start and run. when cranking the noid light doesnt start pulsing until it cranks for a while and when it does light the noid its very dim. the injectors have strong 12V but very weak ground. also noticed after the display times out with key on, it will not reenergize after cranking unless the key is turned off then back on. i've load tested the ground wires at the ECM,checked all connections, and replaced the crank sensor, nothing changed. any ideas? bad computer?
