2001 Ford Escort fuel injectors

He said it did not throw any codes because it is a no-start, however, about a week ago check engine light came on and he put on cumputer and code came up mass air flow sensor. He reset it and said it would be okay until I saved the money to buy it. It is about 140.00 and I only drive about 50 miles a week. I am disabled - lupus - and do not get out much. This was also told to me by auto parts store it would be okay to drive for a couple of weeks until I got money for part. Both said it controls airflow for emissions and regulates better gas mileage and such

I did get stranded yesterday, drove fine to store, came back out and car would not start, had it towed, that is when neighbor checked it out and said it was getting fuel and fire but was not spraying and did not know what would cause the car to tell the injectors not to spray. That was my original question - as far as your reply, get diagnostic, he said it is a no-start, so how do you get a code to tell you if it is a no-start

Thank you for the info, I will ask him what kind of scanner he has, it could be he didn't even hook it up and is waiting until today. If he does not have this scanner, i'm sure ford dealership does, do they charge to do this test, (i would have to tow it there) and about how much.I live in waller texas, 77484, is the closest dealership tomball ford?

I really appreciate the time, advice and help you have given me. Again thank you for the help!
