How do you check fuel pressure on a 99 miata, I did not see any check valve, and what is good pressure and what is bad pressure?? I am pretty sure the fuel pump is gone. Today I check spark, I have spark, and assuming I have air, with a good air filter. Is there any other way to check and see if the fuel pump is gone?? I know with some cars you can check with a DVOM if so where do you hook up. And my last question does any one have the steps or the manual to change a fuel pump??
