are you saying my mao semsior is bad

It's either that, the wrong type, or wiring.

Hey. You also have a cam sensor code. Cam sensor drives the injectors, crank sensor for the ignition.

That should run without the cam sensor. If this is a no start we're talking about.

And yeah the MAP is bad wrong. Need a part number off that thing.

No problem. Good luck with it.

Incidentally I'm getting ready to put an LSA in a C4. One of the nicest C4s I've seen since they were new LOL. A true unicorn.
