2000 solara not starting

Check for.dirty ir.loose.connection.at the terminal to wire connection also all ground wires leading from battery fusable links are inline.with wires they look like little.rectangular or.round erasers on the wires check. Owners manual or download a free repair manual online fir.ground locations and fuseable link locations. Also check all fuses and relays associated with starter and main relay a bad engine to frame/body ground wire or connection will cause car to not.start.

Never seen a fuseable link between starter and battery, however their is a starter relay switch which may be bad

The battery and alternator may have been ok.
You have a fuse or fuseable link between the alternator and battery to protect it. If you have battery voltage at the battery post and not at the alternator post, there is a break in that circuit.
If the battery cable goes to the starter, the alternator wire may go from there and that could be where the fuseable link is.
Fuseable links are special thin wires that act like fuses.

Check all wires from positive battery cable for fusible link,wire may be burnt or melted.

check your ignition switch. It's on top of your steering column also check the starter relay and the fuseable link under hood on fender looks like a wire but has a tab on it that says fuseable link also the neutral safety switch that stops the car from being started in gear

You have a open maxi fuse or a fuseable link you will need to start at the battery terminal and look for a open fuseable link,from there inspect the starter for a open fuseable link, the inspect the engine junction fuse box for any open maxi fuses

will not blame anyone 1st have you checked the black fuse box under the hood?if not,then look for main relay box(black) remove the cover,then look under the cover lid for relay locations. find starter relay.have some one Put their finger on top of the black square starter relay,then you turn your key switch to "on" does the relay that the fingers on click? if so,its'good. you also have what garages call a fuseable link.it's a hard black peice of rubber thats located in between the starter and the battery. but 1ST LETS COVER THE MAIN ISSUES WITH NO START! IS BATTERY FULLY CHARGED?A MUST! WHEN YOUR CAR IS ALL THE WAY IN PARK AND YOU TURN THE KEY TO START,NOTHING AS MUCH AS A CLICK? DID YOU HEAR A CLICK? GO TOWARDS A BAD STARTER CONNECTION,OR BAD STARTER.ARE STARTER BOLTS TIGHT? IS BATTERY TERMINALS TIGHT,THINK I ASKED THIS EARLIER BUT JUST 2 B SURE.

well, kinda. there are "fuseable links" and relays that power big chunks of the vehicle's electrical needs. no electricity NOwhere? if that's accurate I would focus on battery, cables, and especially connections. use jumper cables to bypass positive and negative cables to test. voltage (use test light) to starter? if you jump the switch wire on the solenoid to the positive post, the starter engages? If you have power between the engine and battery, SOMEthing should be able to come on, if you're sure you're to this point, then focus on fuseable links and relays. if you are a novice you will want to tackle stuff at this level, the smartest thing to do first is get a manual.

Battery cables off the starter ,starter relay and ignition switch. these are the remaining items in the starting system for no crank and no start.
Get Shop manual and do the appropriate testing for each.

I would check with vom voltage at battery terminals and at starter to ground. Is possible could be a fuse or fusable link but I think the positive goes straight to starter and power distribution fuse or fusable link
