We found the problem by taking the truck to the dealership, after spending $550.00 on parts and having everything we could remove tested or we purchased them new and replaced them. We spent two weeks on it and took it to Chevrolet but it took them three days after all we had done, the problem turned out to be the gear on the distributor, sure we replaced every part in it but because we could not get the distributor out with the intake on it we had not even considered the gear, thanks for your assistance and maybe we'll try you again next time....Thanks again.

SOURCE: rough start and misfire

first of all you say you took out the plug you may have to replace the boot on the #2 spark plug and where you said it is fill with gas look at all of you injectors on that side and the fuel rail to make sure nothing is leaking at all use a flashlight when trying to find the leak cause its safer that way.

No and No...And it's the "MAS". "Unhooking" the MAS will place your ECM in the "limp back" mode...in other words it will run like ****.
Did you try the O2 sensors (3)? These are notorious for failing. Try a cheap fix...Buy a can of "SeaFoam" at Advance Auto Parts ($9) and add to your tank per instructions.
Good Luck

SOURCE: replacing spark plugs on a 2004 chevy malibu

2.2L Engine

  1. Observe the following service precautions:

    Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
  2. Turn the ignition OFF .
  3. Disconnect the Electronic Ignition (EI) module harness connector.
  4. Remove the spark plugs using a 5 / 8 inch spark plug socket.

To install:

WARNING Do not coat spark plug threads with anti-seize compound. If anti-seize compound is used and spark plugs are over-torqued, damage to the cylinder head threads may result.
  1. Inspect the gap on the new spark plugs, re-gap the plugs as required. The spark plug gap specification is 42 inch. (1.0 mm).
  2. Install the spark plugs and tighten to 15 ft. lbs. (20 Nm).
  3. Apply dielectric compound to the spark plug boots and make sure no corrosion is present.
  4. Install the ignition coil housing to cam cover and attachment bolts.
  5. Tighten the ignition coil housing bolts to 89 inch. lbs. (10 Nm).
  6. Connect the EI module harness connector. Push in until a click is heard and pull back to confirm a positive engagement.

I have a 95 Chevy 1500 truck 4by 4 and I can't get it to start I tried everything it seems like it wants to start but nothing what could it be


well if it won't start it won't start...because your engine has lost 1 of 3 things that make it run: gas, spark, and compression. Don't tie yourself into knots over what it could be. Do the basics first. 1.Check that the engine is getting gas into the cylinders.
2.Check that the spark plugs in the cylinders are getting ignition current to make blue snapping sparks when tested.
3.If you have both spark and gas to all cylinders, you should do a compression test of the cylinders to know there is enough compression in the cylinders to make it run. Without good compression readings from all cylinders, no amount of money thrown at it will make the engine run better, you have to do mechanical repairs to the engine that restores compression first.

Most times, sudden no starts are gas or spark related. Check those first. Happy Holidays.

2004 chevy can spark plugs cause scanner to read tps on a 6.0 l gas 2004 chevy silverado


It shouldn't. The TPS sensor is voltage based on throttle position. If the plugs are bad, you should get a separate cylinder misfire code only. If you are getting a TPS code, it is likely the TPS. Remember too, it is an electronic TPS, so there is a sensor on the accelerator pedal assembly that it talks to. Make sure that's plugged in. What you can do is with the vehicle in the on position (not running) - push the pedal all the way to the floor a few times. Also, clean out the throttle body and ensure there is no gunk preventing the throttle body from opening smoothly and all the way. Good Luck.

6.5 chevy 3500 no start


Check for trouble codes. Battery good? Doe engine crank over at normal speed?
Gas, air, spark, and compression: what the cylinders need to fire. No starts are usually gas or spark related. So check for spark at a spark plug wire end to see if ignition related problem, and check fuel pressure for a gas problem. Do you hear the fuel pump turn on for a couple of seconds when you turn the key to on?

Can,t get truck to fire ,just put fuel pump in . checked fuses,made sure fuel is pumping


the truck has to have the basics . Spark fuel and compression in that order. Remove a plug wire from a plug either remove the plug or install a different one in the end on the wire and crank the engine with the plug laying on engine ground in good view and see if there's spark. Being you did'nt mention what motor is in the truck, desiel. 10 cylinder gas 8 cylinder gas 6 cylinder gas 4 cylinder gas I can only guess at what kind of engine were working on. The gas engines have spark plugs as the desiel has glow plug heating system and direct fuel injection. Silveradoo is a trim level and theres 1/2 ton 3/4 ton 1 ton and 1 1/2 ton versions. They all have fuel pumps and if they have more than on tank or a desiel they can have more than one. The gas engine v8 has troble with the ingtion and the module is the most likly for the cause of no spark but the mileage wasn't stated so I have no idea where to start. if it still is'nt getting fuel with the new fuel pump it's still possible that is'nt running or if it is its wired backwards and is pumping backwards. If the fuel pressure checks OK (above 50 lbs. that part shold work. Below 45 lbs they might run but they won't start. Compression has to be good 100 lbs or more on any engine. most chevy engines are much more in good shape.150 or even as much as 220. low compression and it was running OK the last time it ran sort of says the timing chain skipped as the compression normally does'nt go away quickly. The exception to this is overheating and racecar type blowups. some engines after overheating will have little or no compression and if started with added fuel and revved up they can unstick rings and or valves. and go back to normal. the reason for the overheating needs to be found as this happens again the motor might not come back to life.

I have a 2004 Chevy Silverado. After I fill up the gas tank and start the truck the engine stalls unless I give it gas. After I drive the truck down the road it runs and starts fine.


You have sediment in your tank that gets losened and blocks your fuel line after you gas up. drain tank and clean and change both fuel filters and that should fix your problem

1986 Chevy s10 won't start


small gas engines 101. gas+air+compression+spark=vrrrrrrroooooommmm
i doubt its a fuse. make sure all cylinder have good spark. try and run some seafoam through the gas tank and i would look at the timing - im not sure how you know the timing didnt skip but that sounds like your problem.
