If you didn't replace one spark plug wire at a time you may have mixed up the firing order.

The spark plug wires connect in the 7,3,5,1, 8, 6, 4, 2 order on the 350 motor for the Chevrolet Silverado made in 1990. This changes in the models built after 1990.

That would depend on which engine size you have

Find the tower with the #1 spark plug wire. Going clockwise from here, the firing order is 18436572.

The firing order on this engine is 1-3-7-2-6-5-4-8. Look at the distributor cap. There should be a number 1 in about the 1 o'clock position. The first plug wire goes there. On the other end, place the wire on the number 1 plug, (the plug on the passenger side closest to the grill). Next, going counter clockwise on the distributor, follow the firing order. So the next wire would be number three, then number seven, and so on.

In general (very loosely) a misfire can be a bad plug, wire or coil.

It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.

The speed sensor for a 1990 Cadillac Deville is located on the side of the transmission. Look for a 2 wire plug with 18 gauge wire.

Defective spark plug, bad plug wire, burnt valve, cracked head, or blown head gasket.

There is no specific order that you have to follow to replace the spark plug wires. My advice is to replace each wire one at a time in order to not get confused which is easy to do. Just remove one wire, get a new wire the same length and replace that wire. Then move to the next wire.

On top of the intake in front of the throttle control. it has a two wire plug going into it.

The ground wire is melting on the 1990 F150 when trying to start the vehicle because the wrong wire is being used as a ground wire. The wires are color coded. Perhaps the factory made a mistake with how the wires were hooked up.

Check in the chilton manual, if u do not have one, the main library usually carries them.

Your Electronic Ignition Pack, a black box your spark plug wires come off of should have it written on the top beside each plug wire. I think the firing order is 1-6-5-4-3-2 though.

COUNTERCLOCKWISE ( I'm not yelling ! )

The brown is a live wire in a plug and it is also a fuse terminal in the plug.

Near the intake manifold, a small plug and wire sticks out on the pipe.

Check the spark plug and the wire on the 8th spark cylinder. Corosion, short, or just bad.

User Avatar

you may have plug wires on wrong plugs. you need to get the firing order, find number 1 on distibutor, conenect plug wire from there to number 1 plug . then repeat this using the correct firing order and doing one plug wire at a time

i had the problem with my 97 f150, the power wire to the computer had melted on the manifold and had to be replaced, check the wire to see if its grounding out
