Could a fuel filter in vw 1600 beetle cause backfire


very unlikely
back firing is from partially open inlet valves , incorrect firing order , shorting across the points , faulty condenser , loose coil wires or faulty pigtail wire from the points plate to the ground ( distributor body)
seeing as to you have put in new points , I suspect that the condenser lead is shorting across to the points plate where it attaches to the moving point spring
also if the firing order is wrong after replacing the distributor cap that will also cause the problem

Honda ctx200 fresh rebuild ran a couple times but started stalling backfiring when warmes up. took cover off found cam out by one tooth. adjusted and out together now it wont start at all. help please


Is it a dual cam engine? If so make sure can gear marks are aligned. Verify distributor is installed correctly set firing order is correct.only two things cause backfiring. Incorrect timing or incorrect plug wire position at distributor cap

I have a 1997 chevy 5.7 turns over good but will not crank up it back fires and sounds like it is out of time or cross wired but have timed all marks with distributor all wires are correct it gets fuel ...


There could be many reasons for it not starting and the backfiring. First, when did it start? Did you do some work on it? Were you driving at a high RPM? Did the engine make any unusual noise? Was it raining or did you drive through water?
First if you have rerouted any spark plug wires, make sure that they are in the right place and firing order. Number 1 cylinder is on drivers side. #2 is front on pass side. Make sure that the dist cap is dry and does not have any carbon tracks.
Pull all of the sparks plugs out and do a compression check on all 8 cylinders. If all are ok, check to see if #1 cylinder @ TDC corresponds with the timing mark on the balancer
Pull the valve covers off and check if any push rods are bent or if a rocker is damaged. A bent valve will cause a backfire through the intake..

Magnet shavings inside distributor cap


. No they are not . It indicates that the distributor shaft is either bent or loose on the drive shaft. allowing the rotor button to touch the pins in the cap. It may also indicate that the mechanical advance is failing.

Spark plug wires installed wrong


I did this also recently, but I also changed the distributor cap and rotor. THAT was my problem....Distributor screw tabs on distributor are plastic and can break off.....1st...Make sure you installed the wires in the right firing order. If they're correct, check your cap and rotor and make sure they are seated correctly. If the tabs broke off, Napa makes a metal U shaped piece that fixes this.

I have a 1993 chev pick-up v6 4.3, i just installed new spark plugs,new plug wires, distributor cap and rotor button.All plug wires are back in the right position,and i used the firing order 1-6-5-4-3-2...


This diagram is for 1998-1995 Chevy 6 cylinder 4.3L engines.
Your got the firing order exactly correct, at 1-6-5-4-3-2, but here's the thing to double-check:
The distributor rotation is clockwise (note badly rendered arrow in picture).

Since you probably got everything right, then you're left with really unusual/rare causes of
failure of the ignition system:
(a) rotor button misaligned/failing to make contact?
(b) rotor button not pressed onto distributor shaft far enough therefore failing to provide correct
proximity to distributor cap contacts when coil fires
(c) coil wire or contact loose/disconnected - press coil wire firmly down into distributor cap.
(d) distributor shaft of other damage caused during installation of rotor.
(e) spark plug wires defective from factory
(f) spark plugs defective from factory
(g) battery low - may need a charge to start
(h) ICM (ignition control module) failure - hook up your HEI (high energy ignition) tester, and
watch the quality of the spark on each cylinder.
(i) fuel problem? If spark is being properly delivered, its gotta be a fuel problem...
(j) distributor cap not screwed down flush to top of distributor? maybe just on one side?

Inspect the inside of the distributor cap - if there are lots of little metal bits all over the inside
of the distributor cap, then you know you have a misalignment of some type in there, and the
rotor and cap are destroying each other. normal operation will throw a quota of spark-ed off
metal bits inside the distributor cap, but since your cap is brand new, your attempts to start
the engine should have rotated the distributor so few times, you should see no metal debris.

Inspect the distributor cap contacts to see if any spark marks are more of less in the middle
of the cap's proper "contact zone". If not, you've diagnosed an internal misalignment, which
you know how to correct.

I have a 1979 350 small block #2 cylinder is not firing and backfires through the carburetor when accelerating but seem to idle fine. We have done compression test 150lbs per cylinder and removed the valve...


your on the right track,change the dist.cap and rotor, if that doesnt solve the problem then you may have a bent valve or bad lifter or worn lob on the cam!!!

I just changed all spark plugs and wires with boash platium +4 spark plugs and boash wires. the problem i'm having it's only firing on 5 not 6, i checked all wires and there in the right places. I have...


1. Double check the connections at BOTH ends of the wires- at the distributor and at the plug. 2. Make sure each spark plug boot has proper connection. 3. Double check the plugs to make sure that they are all gapped correctly and no contamination. 4. Hold each spark plug upright and make sure that the ceramic insulator near the tip isn't loose and sliding down and possibly covering the metal tip..(had this happen more than once) 5. Check for spark at each plug (be careful) 6. Open the distributor cap and double check all the exposed metal connectors are clean. 7. buy one extra plug and change out the suspect plug.

1984 Ford E-150 Econoline van It has no spark


Are plugs and wires good? Did you check distributor? Firing order correct-timing set right? Maybe some of the new parts are faulty? Are grounds all secure and are fuses good?
