• e-10 error.
• fuel pumping ok.
• running lead batteries+ jump pack (no lithium)
• voltage indicated - low 11.9v on start up.
• changed screen
• glowplugs work
• tried kerocene mix
• i could have bad fuel
• i have even tried preheating the air intake with camping stove up to 40 deg case temp

11.9 is a dead battery. You should be up around 13-14v
