My son has a 1986 rx7 non turbo, I can get it to crank over but it will not stay running.
I have replaced the fuel pump and fuel filter but have had no luck. i had it running a couple of weeks ago but no luck now. Any advice would be greatly appreciated.
Thank you

 

Check for vaccum leaks, and see if it will run when given some throttle. Checking for codes would also be a good idea: http://www.teamfc3s.org/info/article...odes/main.html.
