Car stalls and then cranks and won't start. Then 30 minutes later will start but then stalls, etc.
Have replaced fuel lines, fuel pump, max air flow sensor. Out of ideas and almost out of money. Please help.

When the problem occurs, have helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. I haven't looked your security system info?

I have requested that he check both those items now. Not sure how long it will take to get back to you as I am not in the same location as the car.
Thank you for your help!

Use a noid lite and check for injector pulse. You need to check for codes.
