As far as no start diag: While looking at the MIL light, crank the engine over. The light should go out. If it stays on, look at the stator/pickup as a primary cause. Cycle the key several times, depress the shraeder valve on the fuel rail to see if there is any pressure. Can't remember if the TFI is on the distributor, or if it is a remote mount. If it is a remote, chances are it is OK.
Pull codes, just to ck for any "fuel pump primary" codes. If you see that, look at the IRCM, tap on it to see if a fuel pump relay is sticking.
No starts are not too difficult on these.
Oh, usually they do not require machine shop work, usually. Just depends. The most common blowout is between outboard #4 and the water jacket. We did a lot of them and only replaced the head gasket.
Tough remembering this 20+ year old stuff.
You have to have them pressure checked and the surface brought to the correct RA for the updated gaskets to work. Just slapping gaskets on is rolling the dice.
