What is the wiring diagram order on the distributor cap for a 1989 Ford E150 van?

Answer Firing orderThe firing order for a 302 (5.0) is 15426378 and a 351W (5.8) is 13726548. Be aware that both engines fire in a counterclockwise rotation. The 300 6 cylinder is 153624 with a clockwise rotation.

The HO 302(5.0) has the same firing order as the 351W. Generally speaking, older 302s have the 15426378 firing order, while newer "5.0" 302s have the 13726548 firing order. The proper firing order for the engine is usually cast into the intake manifold.

What is the correct firing order for a 1971 Pontiac gto?

1-8-4-3-6-5-7-2. The driver's side (left) bank is the the "odd" side starting closest to the water pump at #1 & ending up #7: 1-3-5-7. The Passenger side (right) bank is the "even" side at 2-4-6-8. Pull the coil wire, lift the distributor cap off & leave the rotor on. Pull the number #1 sparkplug out & gently bump the starter until you feel compression in the plug hole. Bring the crank pulley up to the TDC mark while watching the direction of rotation of the rotor. When you reach TDC, note the position of the rotot versus the plug wire location on the cap. It should be under the #1 sparkplug wire lug. If it is, then the next plugwire will be #8 & on thru the firing order. It's easy once you see how it ties together. Good luck & have fun.
