Fouling occurs when the spark plugs' firing tip becomes coated with excessive fuel, oil, or combustion deposits so that it is unable to produce a spark. A plug can become fouled from continuous low speed driving, improper spark plug heat range (too cold), improper timing (over-retarded), too rich an air/fuel ratio or an oil leak into the combustion chamber. A variety of self-cleaning features are designed into most plugs to reduce fouling.

I have a miss in a 5.7 chevy replaced plugs wires timing chain mass air flagging 1,2 and 3 all have 180 compression also replaced distributor new cap and button


What year? Does it have a distributor? If so, possible distributor cap/rotor issue. If coil over plug, you need to run a compression test to see if a cylinder is weak/valve issue

#1 plug on the distributer


Put number one cylinder on compression top dead center, then look where the rotor on the distributor is put a chalk mark on the distributor housing, then install cap. Where mark and cap lign up to distributor cap terminal tower that is number one. Make sure you follow firing order and which direction distributor turns and put on the rest of wires. (example firing order 1-5-3-6-2-4 is on a six cyl.)

Ignition mystery! 1994 GMC Suburban 2500 5.7 mtr. No spark to spark plugs. Have spark from coil to distributor. Have changed coil wire, cap, rotor, ignition module, and coil. have 12.5 volts going to...


I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

#5 CYL MISFIRE


could be the fuel injector if it is stuck open or shorted to ground. check the compression first on that cylinder. if the compression is good check the fuel pressure bleed off time. if the pressure drops more than 20psi in 15 minutes it very well could be a faulty injector.

Hello there good man or woman

Lets start off like this there is 50 different things that can cause these issues but will start with the simple things in a list. So here it goes

1. bad spark plugs (carbon fouled,fuel fouled,oil fouled, heat glazed, or just worn out rounded electrode's )
2. spark plug wires (there is no simple way to check this but there cheap and easy to try)
3. distributor cap & igniton rotor (or coil pack if so equipped) could be corroded carbon glazed heat glazed again thought both rotor button and distributor cap are cheap and easy to change. If it is a coil cheap to and just as easy on both this is were plug wires connet to on the oppsite end of spark plugs.
4. coil pick up (this sits underneath distributor cap and rotor and is cheap and easy to fix aswell)
5. clogged air filter
6. bad pcv valve
7. bad egr valve
8. bad fuel pressure regulator
9.bad fuel pump or clogged strainer
10. vaccum line leaking or off

I know with all that being said may sound overwelming but most are easy to fix and cheap this is what i would so first do a good tune up this includes new spark plugs , plug wires, air filter , pcv valve,fuel filter distributor cap and rotor (or coil pack if so equipped ) .

That will most likley fix your problem

If it helps please leave 4 thumbs up and if it works a testomnial thanks

5 years ago for cap & rotor???? It sounds like it's in dire need of a complete tune up - plugs. wires, cap, rotor, all fluids & filters ESPECIALLY fuel filter. I'd start there and run a good fuel system cleaner through it. Do your tune ups more frequently like every 30K - not wait 5 years!

Changeout the rotor button and cap. the cap has carbon pins under there and wear down from the rotor button. The rotor button sits on the distributor which is easily pulled off. When removing these be sure the plug wires stay in order, Also, use di-electic grease on the plug wires, prevents moisture getting there and run away sparks. CAP/ROTOR button $20 approx.

Replaced entire ignition still no spark 88 305 ci


There are 3 possibilities. 1 the coil. 2 the ignition module. 3 the pick up coil. In my experience the ignition module is the most common cause. It is in the distributor held in with 2 screws. The coil and module can be tested at any parts house. Good Luck
