What is the firing order for a 1951 chevy straight 6 cylinder motor. wires have been taken off and not sure how to put them back.

Hi Jessica:
If this is the straight 6 cylinder motor, they were basically very similar to the chevy. The firing order was 1 5 3 6 2 4
If you look at the distributor, find the number 1 plug wire, and then check from there it should confirm it for you.
Gotta love old chevys!

I'm guessing that you have a 6 cylinder, because that is the only engine my book shows for 1951. The cylinders would be numbered in order from front to back. The firing order is 1-5-3-6-2-4. Hope this helps.

1-8-4-3-6-5-7-2 is the firing order it rotates clockwise and #1 on the cap usually faces towards cylinder 1.number 1 cylinder is the front cylinder on the drivers side of the motor and it goes 1-3-5-7 front to back on that side of the motor.and 2-4-6-8 on the passenger side of the motor front to back.

From standing in front of car and facing engine:

3.1L and 3.4L OHV V-6: The cylinder location is from left to right (rear cylinders) 1,3,5
(front cylinders)2,4,6

The coil terminals from left to right: 5,2,3,6,4,1
Firing order 1,2,3,4,5,6

3.4L DOHC V-6: The cylinder location is from left to right (rear) 1,3,5 (front) 2,4,6
The coil terminals are from front to rear 5,2,3,6,4,1
The firing order 1,2,3,4,5,6

3.8L V-6 cylinders left to right (rear)2,4,6 (front) 1,3,5
coil terminals front to rear 1,4,5,2,3,6
firing order 1,6,5,4,3,2

Sounds like your timing is off when you placed the distributor back in or your spark plug wires are crossed. Start with the simple and check the spark plug wire firing order. 1-8-4-3-6-5-7-2 Cylinder numbers drivers side 1-3-5-7 radiator to firewall. Cylinder numbers passenger side 2-4-6-8 radiator to firewall. Distributor cap #1 is at 5 O'clock and rotates clock wise. Once that is establish to be good then make sure the cylinder 1 is at TDC with the distributor rotor at the #1 position. Good luck and hope it's a crossed firing order.

put the cylinder one on TDC
pull the cap off and look at witch one the rotor is on..
then going clock wise here are the firing orders depending on which engine you have...
4 cylinder 1-3-4-2/ 6 cylinder 1-6-5-4-3-2/
8 cylinder 1-8-4-3-6-5-7-2

you need the firing order?? it is 1, 6, 5, 4, 3, 2 clockwise. Number one on cap is forward position, or 6 o'clock position, just left of the hold down bolt.

The firing order for the 4.9 L engine is 1-5-3-6-2-4, with the firing order rotation on the distributor cap going clockwise. For the 5.0 & 7.5 L engines, the order is 1-5-4-2-6-3-7-8, and the 5.8 L engine is 1-3-7-2-6-5-4-8. On all three of these engines, the distributor cap firing rotation is counterclockwise. Also, on the six cylinder 4.9 L engine, the cylinders are in a "straight six", with #1 cylinder starting in front, and going in order straight back to #6. The eight cylinder engines' cylinders all fire in order also, (standing in front of the vehicle looking back towards the firewall) with #1 being front on your left and going straight back to #4, and then #5 being at front right, going straight back to #8, with the distributor being front and center. Hope this helps you out.
