Injectors lose pulse and car will die. Wait five minutes car car will run fine. Replaced computer, all tune up parts, and crank sensor. When car does start it runs like a champ. Puzzled?

 

This is going to get locked quick, but having had experience...

You might want to check the resistance between the underhood fuse panel and the fuel injectors. Also the same between the fuel injectors and the PCM.

Chances are that you have a high resistance somewhere in the fuel pump harness OR somewhere between the ignition module and the PCM. May also be a problem with the wire connecting the 7x CKP (on the back middle of the engine) to the ignition module (I have seen that happen as well).

This would be easier to tell with a scanner or something, so that you would know whether the injector pulses or 7x CKP pulses are dropping out first.

 

Thank you so much. I will give that a try I have heard the Luminas had injector problems in the past. Will let you know what happens.

 

Also check the injector resistance, both when cold and hot. Per injector should be no less than 11.4 ohms and per bank 4 ohms.
