Why does my GMC Vandura crank but not start, or die and lose all its lights?

Short answer: If a Vandura dies and loses its lights, check the battery and the main positive connection at the battery and starter first. A terminal you can turn by hand is too loose. If it cranks but won't start, use a quick starting fluid test: if it fires, chase fuel; if not, chase spark.

Symptom: The van cranks but won't start, starts and won't restart, or suddenly dies with no lights.

What to check first

1. Try to turn each battery terminal by hand. If it moves, clean and tighten it.
2. Check the positive cable at the starter.
3. Spray a little starting fluid into the intake and try to start.
4. If it doesn't fire, check for spark at a plug wire.
5. On a 1986, run the VIN for the headlight switch recall.

Likely causes

1. Battery or positive cable connection. A loose or corroded main battery connection can let the van start and then die, and take the lights with it.
2. Fuel delivery problem. If starting fluid makes it run briefly, the engine isn't getting fuel.
3. Ignition problem. If starting fluid doesn't help, check for spark at the plugs.
4. Headlight switch. A faulty push-pull headlight switch can cut lights and other circuits.

Is it safe to keep driving?

A van that dies and loses its lights while driving is dangerous at night. Fix the connections before driving it.

DIY or shop?

Battery connections, starting fluid tests and spark checks are DIY.

Recalls, bulletins and complaints in plain words

• Related recalls: NHTSA lists 86V131000 (some 1986 vans: the push-pull headlight switch can have contacts that cause intermittent headlights) and 06E043000 (certain aftermarket FRAM G3727 replacement fuel filters fitted to 1987-1995 vans).

What owners report

• In 1993 GMC Vandura mind boggling issure on Car Talk, a 1993 Vandura's owner removed the A/C compressor and fitted a bypass pulley; later the van died the instant the headlight switch was pulled, and then had no lights, a scrambled radio and no start. The owner replaced the headlight switch and a fuse. Members said to check the battery, the battery-side positive connection and the starter connection, and that a terminal you can turn by hand is too loose.
• In Help with 1990 GMC Vandura on Car Talk, a 1990 Vandura 2500 cranked but wouldn't start, and once running it might not restart, hot or cold. Members said to spray starting fluid in the intake: if it runs briefly, it's fuel; if not, check spark, then compression.

Quick tip

Coincidences fool people. If it died right after other work, still check the basics first.
