My 91 fj80 is giving me this prob sometimes when I've got it to operating temp. I'll cut it off for a bit. Try to restart and it'll turn over fine but won't start. Tries to kick off but won't. Changed mass air flow meter, plugs,wires,cap and rotor. Evap canister was changed too. Today I was able to try some starting fluid when it did this and it started right up and ran fine....? Anyone have the fix or help it'll be appreciated greatly! Thanks
