I just bought an 87 that didn’t start. I replaced the ignition switch and starter and still no crank no start. Has anyone else have this problem and can anyone help.

 

Is it a M/T or A/T ? If it's a M/T check your inhibitor switch or inhibitor switch relay those years had weak relays make a bypass jumper and bypass that crap! If it's an A/T make sure the shifter is all the in park maybe place your hand on the shifter and push it fwd a little! Check your battery terminals as well my suggestion is to invest in some heavy duty marine type battery terminals that are super thick and made of bronze/brass.
