My daughters car wasn't starting its an 07 Hyundai Tib 4 cylinder. It would almost start and backfire occasionally but not fully crank. I changed the Crankshaft sensor and Camshaft senor with no luck, new battery, new fuel pump, verified fuel was getting to fuel rail and all 4 plugs have spark. I started digging around checked all fuses and relay's I could test. I noticed the car had an aftermarket alarm that we never received a key fob for. I noticed their was a fuse missing under the dash in the alarm wiring when I put the fuse in the alarm went off so I assumed the alarm was causing the issue. I removed the alarm and put all of the factory wires back together and now the car won't turn over at all. When I insert key and turn the key all the dash lights come on. Any help would be greatly appreciated. I have tried to find an ignition wiring diagram for her car but haven't had any luck.

if its backfiring the first thing thats coming to mind would be timing/ignition, id start there
Thanks, right now I am trying to get it to turnover again after removing the alarm it's not turning over and I don't know what I am missing.
Yes battery and starter are both good. Was turning over prior to me removing the aftermarket alarm. I respliced all the wires back to the original factory wiring. Not sure what I am missing. An ignition diagram would help but I can;t find any for the 07 Tib I am working on.
if there is a dealership close by, might swing by and see if they can print you up a wiring diagram, does the dash light up when you turn the key to the on position?
So somewhere between your igniton switch and your starter, im not for sure if they have an immobilizer installed on those or not
2006 Tib Turns Over But Won't Start - Immobilizer?
Hi there, new to the forums, and glad to be a part! We have a 2006 Hyundai Tiburon SE that won't start. We came back from holidays and it wouldn't go. Worked fine prior to leaving. Tried it numerous times until I killed the battery. Boosted, tried again, tried trickle charging it - but the...

The aftermarket alarm likely had an immobilizer relay that would "cut" the starter if the unit thought the car was getting stolen. This relay is usually connected to the starter wire, I would start by looking at the ignition switch and checking if any of the wires were cut and re-routed elseware. if they were, I would cut the aftermarket wiring portion out and just connect the factory wires back together. Looks like the starter wires at the ignition switch is white, if my schematic is to be believed.
Edit: also, new crankshaft position sensor does not equal good. I had a similar issue that ended up being the aftermarket cps just being garbage. when it comes to tiburons, get OEM sensors.

I have cut out all of the aftermarket alarm wires and have reconnected all factory wires to the best of my abilities. I wish I had a solid diagram of the factory wiring from the ignition.
sounds to me like you might just have to replace the whole harness if possible or try and see if a local dealership can print you off a wiring diagram.
Update: The car will turn over now found that the 30AMP ign fuse under the hood even though it looked good it was bad and failed a continuity test. Thanks for all the help. I am now waiting on new plugs, plug wires and coil packs. Will update again once I get car running.
