not enough infobut e.f.i. cars and some late model carbs are equiped withidle contol moters. some times un pluging i.a.c. will helpduring power ballance test.if you are working on a lt1 or later model it is best tounplug the fuel injectors.
On a 74 Corvette, there is a primary coil inside of the distributor that is usually the cause. I would assume that the engine turns over, but no fire. While you have the distributor apart, you might as well replace the secondary coil, located under the distributor plate too, because if this is the problem, you would have to tear the whole thing down again to fix it, and the parts do not cost that much.
They are above the cylinder. to find them fallow the distributor cap wires to the spark plugs There are no cap wires on the vibe, take the plastic cover off the top of engine. There are 4 coils in center of valve cover, remove them and the plugs are down in the holes where the coils came off.
The intake manifold.
No. The differential heating will probably lock the plugs in place until the engine cools down.
It depends on what kind of engine you have if you have a vortec engine the plugs are under the coil packs you will need to remove the coils first and then the plugs are exposed down inside the engine. If you have a regular V8 then the plugs are located at the end of the ignition wires the wires go from the distributor cap down to each spark plug remove the wires one at a time and change each plug one at a time and replace the wires every-time you replace a spark plug so that you don't mix up the firing order by putting the wires on the wrong spark plug
Imagine a straight line directly down from the center of the distributor. The oil pump is in the bottom of the engine and straight down from the distributor.
You will have to remove the cover that is on top the engine. You will find the plug wires there. You must remove the bolt that holds down the plug to the engine. The plugs are located deep down in the holes.
It is located underneath the distributor rotor. It is fastened down with two screws in the distributor housing. For the best access to it you will need to remove the following: spark plug wires from the distributor cap (be sure to label them for correct re-installation), distributor cap and distributor rotor.
Assuming you have set the engine to #1 TDC and marked the position of the distributor and the position of the rotor, remove the distributor hold-down clamp and it's bolt, then pull the distributor up and out.
down below on both sides of engine!!
Loosen the distributor hold-down bolt. Standing in front of the vehicle looking at the engine turning the distributor clockwise advances the timing. Turning the distributor counter-clockwise is retarding the timing. Hold the distributor steady while tightening the hold-down bolt. Factory hold-down bolt needs a 1/2 inch wrench.
Driver side front of the engine. Just follow the fuel line from the carb down to it.
