Car will not start

Let's start with some info about the engine you replaced. Did you put the same engine in that was there originally just a used engine?

If so we need to find out what we have on this engine and what we don't for it to start. That means we need to know about fuel, spark, and compression. Here is a video that talks about this:

Let's start with fuel as that is the easiest. Use starter fluid sprayed in the intake and crank the engine. Does it start for a second or two? Then pull a spark plug and hold it against the block and crank the engine. Does the plug spark?

Lastly we need to perform a compression test.

Once we know what we have with this and what we don't, we will know what direction to go. Thanks

Okay. That compression is low. It should be around 145 +/- 15 PSI. However, if you are not getting spark we need to follow the testing attached.

Just make sure the theft light is not on or flashing. Let me know what you find with this. Thanks

Haha. It is always the simplest of things. Thanks for the update, I am sure that info will help others. Thanks for using 2CarPros and following up with us.
