If you have coils and spark plugs then you don't have wires. From personal experience these car's misfire because of coils and BAD INJECTORS. If you replaces coils and sparks plugs you need to check injectors. Get a NOID light and check injectors pulse to make sure it good. First you must locate the cylinder that has the misfire/Missing,this can be done by using a computer/code scanner or if can be manually by disconnecting each coil and see when there is NO change in idling or shaking. What you are looking for is when you disconnect the Eugine should shake more and when you reconnect it would smooth en out. If any cylinder when disconnected the engine doesn't change that the one with the problem. Check again for spark and make sure it good. Then check that injector pulse plug off injector connector and connect it to NOID light you should get a constant flickering of NOID LIGHT. If you do then BINGO that injector is BAD. However I must say this test is on valued if you have performed a compression test on all cylinders to make sure there are no BAD/Burnted valves. This can be done with a compression guage remember the reading should NOT be more than 10PSI difference between all cylinders example of a normal reading is cylinder 1 170 psi cylinder 2 168 cylinder 3 172..... abnormal is cylinder 1 170 cylinder 2 85 cylinder 3 172 ...etc. I know this is alot of info but read through and follow these step and you'll be ASE certified by the end of this job. Good luck and thanks for using FIX YA

05 Ford Escape, coils #3 & #4 not firing. We've replaced the battery, spark plugs, alternator, coil packs, & pcm. Had pcm reflashed. Garage said it had to be coil packs, but just replaced coil packs 3


Check engine light on ? Code's ? What engine ? 2.3 l 4cylinder or 3.ol v-6 This vehicle has coil on plug ignition system , not coil packs ! a coil per cylinder . If new coils an still has no spark , has no B+ voltage to the coil or the PCM isn't controlling them . Without testing i'd only be guessing as to the problem .If the repair shop you had it to can only say it had to be the coils , I'd find another shop to take it to !

1994 ES 300 fire order as cilinder #1


Not sure as a firing order can be explained but here is a picture as to the location of the cylinders for your engine. The coils are on top of the plugs and unless the wiring harness has been removed and you are trying to put back together it should ne pretty basic as the coils will pretty much only reach each plug and kinda hard to put on another plug. As I said am not quite sure what you are looking for other then the number 1 cylinder. I hope this helps you and good luck.

My 1998 lexus 300rx will not start, the battery is good


You say it doesn't start. Does it turn over good, but won't fire? Does it click and not turn over? If it turns over good but won't actually start, you would need to check fuel pressure output from pump, check spark coming from distributor to plugs and the control module could be bad if there's no spark, as well as the coils. If it doesn't turn over, but clicks when you turn the key, you could have a bad starter.
