I had codes for cam and crank sensor and it would cause occasional stalling and no start conditions so i bought a new cam and crank sensor and the car wont start at all now. I thought the crank sensor i instqlled was bad so i put the old one back in and stil no start. Put the old cam sensor and same thing. Theyre both getting power signal and ground so idk whats going on, i didnt touch anything else while installing the sensors.

check ignition fuse under the dash

Every single fuse is good in the car. Checked one by one with a test light.

Have you ever done the cams?

I would check the pick up attached to the rear of the cam to start. I've seen some loose that cause weird problems.

Cams never ever touched. Its a stock motor. The thing though that is happening that is wierd. Is that I tried plugging in a scanner into the obd2 port and the CEL would shut off and the scanner would never get a chance to scan the ECU.

When I turn the ignition off and back on the CEL will come back on but if I try to scan it again it will turn off.
I think this is what is happening when it tries to start- the ECU shuts off. Any idea as to what can be causing this.

Fuses can be tricky. The element can crack or the solder can melt at the base and when viewing the element through the window, the fuse looks fine.

If using a test light, check for power at both terminals. The hot could be at other than where you think it is.

I prefer to pull each fuse and check it with an ohm meter. Then tap it on a hard surface a couple of times and check again. This also gives one the chance to observe the terminals for signs of overheating.

Ok ill try that wit the ohm meter. But Idk why the ECU is having problem being read.

My car does almost the same changed both sensors it starts up the dies couple seconds later because it stops sending pulse to injectors. I'm lost only 3 things to my knowledge crank or cam sensor or ecu.
