My 01 X is not wanting to start periodically .mine spins over until battery dies after trying to start it 3 to 4 times spinning it over for 60 seconds each. glowed it 3-4 times before spinning it. glow plugs has a module not relay and does not have a code. battery doesnt completely die but gets weak and i jump it off with my 4.0l ranger. then when jumped off it fires right up usually on the first try. if it sets for 18-24 hrs back to the same thing. it will start any time after jumping, even if you cut it right back off with jumper cables disconnected. any suggestions? i have an otc genysis scan tool but do not know what to look for. this is my 1st diesel engine vehicle. local ford dealer suggested injector driver module because it had code p1670 (ef signal not detected) once but has not come back on in 3 weeks since i cleared it. the code came on when the battery died while trying to start it. fired up as soon as i jumped it.
