No spark from ignition?

Okay, so I swapped around the computers and the computer it though was bad wasn't and I know that because I put it into the other car I bought that's wrecked and it started just fine. but the car I'm trying to fix still has no spark. so could it be the chip in the key has failed? if so couldn't I just swap out the whole steering column with the one that is wrecked? but still starts again I used the computers from both cars to start it.

When you try to start the car does the security light flash?

No it doesn't and I have the key fob it works as well as the alarm.

car died while running want crank it turns over but no spark ,checked harness,spark plugs, coil, packs, and all the computers we're stumped

Have you checked for injector pulses? Loss of spark accounts for less than four percent of cranks / no-starts. Loss of fuel pressure accounts for perhaps one percent of no-starts. 95 percent of no-starts are caused by a loss of fuel pressure, injector pulses, AND loss of spark.

The first step is to determine if the fuel injection relay is turning on. To do that, use a test light to check for 12 volts on the red wire of any injector. You might see the test light turn on for one second after turning on the ignition switch. What's important is if it turns on during engine cranking.


Heres a couple links that will help you figure out where you are losing the spark
