86 vette wont start when hot

[powertrip]

Hi guys I am new here and have an issue with my car. Its an 86 350 tpi. It will start fine when cold. Then you drive it so it will warm up, then stop shut it off and let it sit for a few minutes and it wont start. It turns over but wont fire. It has spark, fuel pressure, oil pressure. But the thing i do notice is the injectors wont turn on. You can get it to fire right up with some starting aid.
Let it cool down and it will fire right up. It will run just fine as long as you dont shut it off. Any help would be great. Thanks again

Check your resistance of your fuel injectors.

You may have a few shorted out.

16.5 ohms is the spec, +/- 1.0 ohm.

Old injectors can go bad when hot; check resistance when cold and hot to see if they vary

As I recall one injector shorted out( near zero resistance) when hot will shut down the entire bank on that side. So if 1 on both sides goes bad --no fuel.
