99 percent of the time no spark on these engines is caused by a faulty crank sensor or bad ignition module. If you have a scan tool you can read if it has cranking rpms, if not you have to guess and I would give my educated guess at the ignition module.

We have no injector pulse could that cause a problem or is this something entirely different?

We now have spark and the car will start. The car will not stay running now. It runs for 2 seconds and then shuts off. I was told it has something to do with the anti-theft system in the computer.
