Not sure I understand. At this point everything that happened is mute. You now have rebuilt your engine and tried to start it. It didn't work so you checked and the 80 amp. fuse was blown. You went to start again and the check engine light is on but as you cranked the engine the distributor blew? If so explain blew? 80 amp Fuse still OK? Was it the distributor fuse that blew?
You need to manually rotate the engine and set the number one cylinder at Top Dead Center (TDC) before re-insalling the distributor. Hopefully, you made a mark on the distributor that relates its position to the engine in orde to re-install it as it was. If you forgot to make a mark, try to remember in which direction the rotor was pointing before you removed the distributor (assuming the engine was at TDC) and re-install it as close as you can. At TDC, the rotor normally points toward the number one spark plug wire post. Follow the firing order sequence from there.
Remove distributor cap Have assistant crank engine and check to see if rotor is turning as engine is cranked
It is normal. In order for you to create a spark, the coil has to open and close.
Usually, NO.
Get number 1 cylinder up to top dead center on the compression stroke and rotate the dist, rotor to the number 1 plug wire when re installed in the motor the dist make take several attempts cause as it is installed it turns as it messes the cam gear.
The distributor cap should have the number 1 marked on it. The distributor cap is installed with the # 1 position facing the engine , slightly towards the drivers side of the engine
Because the replacement distributor and spark plugs wont fire correctly if it installed in any other position.
The # 1 position on the distributor cap is installed facing to the rear , and slightly towards drivers side of engine
was the engine removed before the overhaul or was the overhaul carried out in the vehicle? was the engine removed before the overhaul or was the overhaul carried out in the vehicle?
The firing order on the 4.9 L ( 300 cubic inch ) straight six is 1-5-3-6-2-4 The distributor rotor rotates CLOCKWISE The distributor cap is installed with the # 1 position facing away from the engine ( if the # 1 distributor cap position is next to the engine the cap is installed 180 degrees out , flip it around ) The engine cylinders are numbered 1 to 6 from front to rear of the engine Hope this helps ( Helpfull )
The spark plug firing order is ( 1 - 5 - 3 - 6 - 2 - 4 ) The distributor rotor turns CLOCKWISE The distributor cap is installed with the marked # 1 position facing away from the engine The engine cylinders are numbered 1 to 6 , going from front to rear The spark plug firing order is ( 1 - 5 - 3 - 6 - 2 - 4 ) The distributor rotor turns CLOCKWISE The distributor cap is installed with the marked # 1 position facing away from the engine The engine cylinders are numbered 1 to 6 , going from front to rear
