do the head lights work????????that is firstbecaus it works key off a speaks volume to any tech wild guess:battery installed backwards or you made sparksremove it or alt or starter.fuses blew.easy peasy japaneezyor worse,there is always that.?elaborations. pretending HL work.buy and $10 voltmeter and end the guessing?5min work and bingo.wow this fuse has 12vdc one side and 0 other.?or key on fuses, same.5minthere are many ways to do this.start at end work backstart and begin (key) and work forwardor the middle (cuts job in half too)so i go to the starter solenoid first.if head lights dead i work them first....starter 3 lugs. outboard lug first.(batter + is battery installed backward?)got +12v on the big lug (y/n) (outside lug)connect meter neg test lead to battery neg lug for all tests.if voltage drops fast? or does crankingbad battery ,starter shorted or cables (or discharged battery) (we use an ammeter to discover shorted starters,or hand turn engine for seized engines. next tiny lug, (called Key Line)it goes hot 12v? cranking. so turn key.does it go hot? (hot means 10to 12v cranking0if yes, goes hot cranking on the tiny lug(yes starter dead , or the battery minus lug is loose , the far end of minus bat cable must be tight.no? that means the KEY line is dead.the car if a/t tranny cuts the key line via the P/N switch,or some immobilizers., i stop here on key line, ask.some cars have wire fuses, looks like wire, and are not. "fusible link wires"if you change out starter or alt without battery neg lug not disconnected in step 1 ,you risk main fuses under hood(blowing or far worse)so what does "good fuses mean" OP? (the looks)>?or just dash fuses. tested skipped under hood.fuses that look bad arefuses that look ok, can in fact have hair line cracks so we actually test them or waste Huge time.and go poor. (tests done wrong are highway-to-h3ll)or looks like dog chasing his tail.0 ohms good12v both sides key on, good.
