Hey guys so I just installed my Megasquirt MSPNP2 in my 1990 Miata NA, along with a GM IAT and a AEM UEGO 30-4110 wideband. Disconnect the negative side battery terminal and pulled the ST SIGN fuse, ran my vacume line, wired up the IAT and wideband, connected the negative side battery terminal again, loaded a base map and calibrated the IAT and set to fixed advance timing to 10 degrees and now my car wont start. It cranks over but does not start, tried giving it some gas and no luck. I am completely new to this so any help I will appreciate it.
