Another good fix to the issue is a manual glow plug override. Tie the lift pump in directly to the gp relay. Key on, lp on. Use a single pole switch to ground the relay. Push a button and your glows come to life. Works excellent. Once the engine has warmed up once and ran for a while, glow plugs aren't required to start engine anymore for remainder of the day.

Saves glow plug lifespan.
