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.

How do i know my spark plugs are firering in the


The best way would be to obtain a firing order diagram and go by that. You can probably look at the diagram somewhere online for nothing. Crossed wires are a pain to guess at.

How to change spark plugs on 1997 ford ranger


Changing the spark plugs is a pretty easy task. The spark plugs run along both sides of the engine (if its a V block) , 1 per cylinder. You can easily identify them by the plug wires running to them from the distributor. Pop off each plug wire, (1 at a time) and replace the spark plug. Once you have replaced the plug, replace the plug wire. This ensures that you dont mess up the sequence of the wires which determines which cylinder fires at what time in the cycle. VERY important not to mess up the sequence. If you should happen to get the wires mixed up, look online for the firing sequence for your vehicle and engine.

Put new plugs and wires in , what is spark plug wiring seq


You need to buy a Hayne's Repair Manual for your car. They're available at most parts stores. I buy all of mine at Autozone. It will have the firing sequence on one of the first few pages. For future reference, if you only remove one plug and wire at a time, you won't get them mixed up. Good Luck.

Turns over then dies right away.


check spark plug wires to make sure they"re not miss-routed... start at the coils and work towards the plugs make real sure its got correct firing order sequence... it is usually posted on a label under the hood of most cars and also make sure they have a real good snap on connection both on coil and plugs and that the terminal posts on the coils are really clean! if this doesn't fix the problem then it probably is a timing chain problem..it might not be installed correctly. good luck to you! i hope its just a miss wire.
can you give me some feed back..i'm curious..thanks! a 40k mile car shouldn't need this kind of work..its practically brand new!!
