Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
I can probably help, but I need some clarification first; do you mean to say the mechanic replaced the pump without first performing a comprehensive diagnosis to see if it was indeed the cause of the no-start?
I'm sorry, but I'm even more confused now... If it was running fine, why then was the pump replaced? Will it start with the old pump? What is the mechanic saying is causing the engine to not start now?
I see. What is the mechanic saying is causing the engine not to start now?
The engine in your Tiburon needs 4 things to run: compression (more than 120 psi across all cylinders), fuel pressure (35 to 40 psi), injector pulse and ignition spark.
Can you have your mechanic try to start the engine with starting fluid? If it does, we'll know compression and spark are good which leaves fuel pressure and injector pulse as possible culprits. If it doesn't crank over or doesn't start with starting fluid, then the issue could be caused by the anti-theft system, in which case we might be able to reset it.
Please let me know what your mechanic finds so we can continue.
OK. Have him check fuel pressure - should be 35 to 40 psi. If OK, then have him put a Noid light on one of the injector connectors and check for injector pulse while the engine is cranking over. If no fuel pressure, then have him check for power and ground at the pump he just installed - he might have blown a fuse.
Please let me know what he finds.
