My check engine light is on in my 2005 impala. I had a mechanic put a code reader in and no problems came back. What is the reason behind this?

The P1350 code on your car is described as Ignition Control (IC) System Fault Conditions. Have you checked your stock coils with a voltmeter? You know I've seen "aftermarket" parts fail pretty quickly. In many cases, OEM replacement parts have the quality you need to have a reliable car. Not all the time, but in some cases. In addition to posting here you might also want to post your question at Good luck!

Something is wrong with the wiring. Coils have to have pulse width current. Something was wired or routed wrong. My first guess is that a wiring harness to your coils has shorted and is causing the coils to stay energized too long. Please write back with more specific information. What are you working on (year, make, model, engine size). The more information you can submit the faster I may be able to help you solve this. Good luck.

The engines should be much the same.
Is the check engine light on ?
Do you know what you are loosing when the engine stops ?
Fuel or spark ?

My engine misses when accelerating and when rpm exceeds 2,000. Check engine code was for cylinder #2 misfire. I replaced the sparkplug and wire on #2, #4, & #6 but, have not figured out how to

Maybe try waiting untill dark ,fire it up,open the hood (kill the hood light)
spray the plug wires with windex(not water) and look for sparks ,if any ,put a set of wires on it. I suppect this is the only problem,bad wires will kill coil packs

I put timi belt and sparkplug on 2005 Kia amanti and ran for 5 min started runnig roughy it to coils put to new coils on it it ran 5minute and died now it won't start

Check the timing. Before I put anything back together I always start the car and make sure everything is okay. After puting the belt on you always want to rotate the crank two full revolutions to double check your timing. This is of course assuming u did the timing belt because of maintenance and not because it broke.

I have a 95 impala ss, i have a brand new opti-spark, plugs and wires. they were changed 2 wks ago. this morning when i started it, it ran rough, then when i patted the gas pedal it hesitated then it would...

What type engine? I assume if it is opti-spark it is a v8. L type .Check the routing of wires. GM vehicles are very susceptible to cross fire . Opti-spark distributors are notorious for failure as timing is achieved by a laser eye reading slots of a rotating disk and sending that data to the pcm. It was GM biggest failure. Check the installation especially the cap. Voltage will fluctuate anytime and engine's timing or firing if not on point.

V6 hard to start.replaced coils sparkplugs . check relays and they check ok put new crank senser in still wont start. no dash lights work and there no fuel pressure on rail.and the motor cranks good and...

I think you've identified your own problem. In your description of the problem, you indicate "no fuel pressure on rail".....

First things first, try replacing the fuel filter. If this doesn't do the trick, make sure the fuel pump is actually pumping (you indicated that you hot wired it with a 12 volt DC supply and it ran). Running is one thing....pumping fuel another. To properly identify issue you need to know the cranking fuel pump pressure. If you can get it to start it would also be a very good idea to check out the fuel pressure regulator.

When you turn the key to the "ON" position (don't crank it, just to to the position where it would run) do you hear a few seconds worth of pump motor activity?

If it tried to start when you introduced fuel into the breather, then I think it's safe to say you have some sort of fuel delivery issue.

you can check for spark by plugging in one of your old sparkplugs to one of the spark plug cables and letting the sparkplug lay on the bare metal of the engine. Turn over engine to see if the spark plug is producing a spark. No spark? Check under the distributor cap, take a look at the rotor for damage.
