420A another no spark and no fuel issue

[Black420RS]

alright well I have a problem with my car and we are trying to solve this

the car starts and runs strong but sometimes it just shuts down and does not start

after several tests we know that the engine doesn't have injector pulse and spark (only when the problem appears) but if I wait around of 10 minutes with the key in off position and try again the engine starts normally and is just a matter of time for the failure happen again

I have noticed that this normally happens when i'm driving through a hill (I know is weird)

after searching here for answers I have checked the 2 relays, changed the coil pack, rewired and tested the fuel pump and fuel pressure in the rail

so I think that the Crankshaft Position Sensor or the Camshaft Position Sensor might be the problem here...

but my big question here is "how can I be sure about this?"

any tips on how can I test them?

*Edit* BTW The ecu doesn't show any CELs

I'd go to autozone to double check there are no codes. Some reason mine didnt have the lamp on but still had a code. But yeah... Sounds like a crank sensor. Not sure how to test it but that sounds like your issue. Check fuses and ground wire.

believe me we have triple checked and there is no codes,

we will check the ground wire on the sensor

fuses? what fuses? all the fuses? or there is a specific fuse for the sensor?

Checked the grounds for the sensors and they are fine, any ideas about a possible cause for this issue??
