Car will crank and turn over changed the starter and the alternator. It makes a quiet beeping sound also. Uh habe gone through all the wires and nothing coroded and im not really sure. Car is a 1988 mazda rx7 fc

 

compression
fuel
spark

you need all 3, not 2, not 1, not a random combination of 1 and 2 but all 3.

the tests are fairly simple to find out which is missing.

i suggest starting with compression, since it rules out the most difficult factor to the equation.

 

I'm having the same problem.. I got fuel/spark... so compression might be the reason? Can I use a normal compression tester to get good results to determine good compression?

 

there's a couple thousand threads regarding compression tests, im sure you can find one.
