Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
hello, my name is ***** ***** I will be glad to assist you. please allow me a couple of minutes to gather some basic info.Roy
ok, there is an engine control relay in the underhood fuse block. if that relay sticks, it will send a continuous signal to the pcm that the ignition switch is on and the engine needs to run.
try removing the relay to see if it shuts off.
ok, first. I would replace that relay and see if that resolves it. if not, then we need to look at the control side controls.
the relay should be available at a parts store and they are cheap to buy.
please dont forget to rate me as it is the only way I get paid for my efforts
are you there
ok, when you pull the relay and it shuts off, does the relay click???
do you have an ohm meter to check some wiring???
I am wondering here. removing the relay, no click concerns me that there may be a wiring issue.
the relay controls the fuel pump and feeds the pcm. wondering if the pcm is getting voltage it should not get.
also wondering about the ignition switch not cutting voltage as well. if you play with the key, will it shut off??
thats not good.
either you have a wiring harness issue or a pcm that is internally shorted
let me look further at the wire diagrams
you dont need to see it or smell it. it could be as simple as a bad diode.
thats something that we as techs cannot check. you need special equipment for that. a parts store can send it out to a rebuilder who will check it and confirm if it is good or bad
I am here and not there. I cannot see it touch it or diag. I rely on your input. we give advice based on your input and our expierence.
as I stated before, either a wiring issue or pcm issue. both of these need to be checked.
