Ive replaced in 6 mos. IP, All new glow plugs, new manual relay, just put in 8 new oem injectors, new starter, new elec fuel pump. Sooooo,WTHeck is going on? I have to glow my plugs at 75-80 degree temps here in Az. Now thats just wrong! Initial morn start, glow then start, lotta smoke, takes while to warm up, at 65 degrees? After, I have to glow, sometimes will start, sometimes not... Driving me Krazy! CDNARSGUY prolly knows the answer..
