SOURCE: not firing right on no.4

First check plug and make sure the right plug for this vehicle,make sure that the heat rating for this plug is correct. Your problem could be a wrong heat rating plug been installed. Also make sure that the misfire is due to a bad plug and NOT a bad injector or injector wiring or uneven compression or even bad coil. Check injector wiring and make sure it not shorting or broken. To check injector pulse use a NOID light can be bought at almost any auto parts store like Auto-zone etc. Also compression can be checked with compression guage. A rule of thumb to go by is if any cylinder has more than 10 PSI in difference in compression there is a problem like a burnt valv etc. Here is a n example cyl# 1 170psi cyl#2 176 psi cyl#172psi cyl# 4 150 psi, there is a problem with cylinder # 4 and will cause a miss from cylinder #4. Good luck and thank for using FIX YA

SOURCE: does the car have spark plug wires?

So you want to tune it up , but someone has to tell you it has no wires? Have you looked at the engine at all? why do you want to do a tune up? The coils are very problem prone, and you need to use care in replacing the spark plugs, use only Auto-lite or Motorcraft platinum spark plugs, and use a silicone grease in the boots. After you remove the coil, blow compressed air down the tube an dblow out any dirt, before removing the spark plug. Wires are/were never an item for a tune up, unless they were bad. Replace the fuel filter.

My husband did a tune up on my car yesterday and now it wont start it will turn over like it wants to start but it wont he said that its miss firing we have bought 3 new coil packs and still will not start...


If your car is miss firing and your husband changed the coil packs,the wires leading from coil packs to sparkplugs must have got crossed.This will change car timing which will result in the car miss firing.He needs to go over wiring and correct problem for car to run right.You can go online to autozone.com and type in Info about car to get the correct wiring layout.Your problem isnt the new plugs n wires.Its the wiring layout.

Ok i recently changed spark plugs on my 1994 buick skylark. when i was done changing plugs i started car up and smelled strong exhaust smell. so i checked the plugs wires and found out that when i pulled...


Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....

Rv backfired then died and wont start know


It could be your control module.Pull off a plug wire and see if it has spark when you turn engine over.
If you dont, it is most likley the module or the coil

Motor won't start


You need 3 things for a start condition 1 spark 2 fuel 3 compression. If you have lost spark and have changed wires and coil then you should look at the crankshaft position sensor. This sensor tells the computer when to fire the coil and which plug to fire. Hope this helps. I will check back on the 14th.
