The ignition timing on a 1980 Dodge D50 Pickup is: 2.0 L engine: 5 degrees BTDC 2.6 L engine: 7 degrees BTDC Additional info FYI: #1 cylinder location: FRONT Distributor rotation: CLOCKWISE Firing order: 1 - 3 - 4 - 2
The distributor is not timed with a timing light. The distributor rotor is lined up with the mark in the pick up plate when the crank is at tdc#1. The computer then does all timing from there.
The distributor is set at 0 deg with a scan tool. The "base" timing is to line the rotor up with the line in the pick up plate in the distributor when at tdc.
depends on if your taking about cam timing or ignition timing and what engine.gm Jim
The timing on a 1989 Dodge truck should be set to 10* after unplugging the temperature sensor.
Drill it out............
0 degrees
On The Crankshaft It Has A Magnet & On The Timing Cover It Has A Pick Up Coil, This Sends The Control Box Under The Coils Information As When To Fire That Coil. The Timing Is Done By The Computer.
The distributor is not set with a timing light. It is zeroed to the crankshaft. Set the crank on its 0 mark, remove the distributor cap and check rotor alignment with the mark on the pick up plate. The dealer can fine tune this with his scan tool.
The engine computer uses it to measure the temperature of the air coming into the intake manifold. It then uses that to help calculate fuel and ignition timing.

Probably distributor cap, ignition timing, timing chain/cam timing or burned exhaust valve(s). Pick one.
It "tells" the computer the rational location of the distributor for spark timing.
