Ok so I changed my camshaft position sensor last month car started up fine until 2 weeks ago I just ran into this problem that every time I go to start her up it gives me like a cold start I would have to crank it a few times for it to start and when it do start the rpm takes a lil time to go to a 1000 rpm like it's not getting fuel or something but it is getting fuel though and their is no cel on can someone help me please thank you

 

I have a engine for 500 bucks that would slide right under the hood
