Another CRX won't start.
 

Oh here's the story to this one. About two weeks ago a guy on my hall came to me with a dead CRX stuck in a mall parking lot. So Me and my friend started looking into it. Since then he bought a new car and we have come into possession of this one. While checking over the car, we have found that the car gets spark and fuel. It used to crank, but since the battery died last night, it won't even crank now at all, (yes we replaced the battery). When we try to start the car we get nothing at all. When we jump the starter it sparks and then spins like it should, but when we try to start the car we get nothing.

After talking with the previous owner, we found that it has a new motor, put in by his brother (not sure what kind of motor and not sure where to find that on the block itself). We also found that he's had this problem once before with it not starting, but it turned out to be just a loose wire.

Any suggestions as to what we should look for/check/do? Thanks

check the starter if not then distributor

Recheck your battery connections. Since you can jump start it, the battery connections may need to be cleaned or the new battery is somehow bad. Is this CRX fuel injected?
