Need help.

Carbon tracks on plugs. replaced plugs and boots. still no start. help.

 

Is that the only symptom? Check the fuel pressure and see if it is getting spark. What did the car do if anything before the problem? As for the carbon tracks put dielectric grease on the boots.

We need more info on the problem to help you.

 

The worst, worn out, junked up, crappy spark plugs will still fire and start the engine.......you have a fuel or No-spark issue. Air....its almost impossible not to be able to start because of no air. Unless you have a rag stuck in the TB and you vacuumed the air out of the intake....lol

Maybe a failed Crank Shaft Position sensor........you'll get zero spark if its failed.

^ Yep. If you have spark, and ifnd you don't have fuel, check relays and fuses.
