So I have a 2002 Hyundai Accent 1.5L. My car will drive 1-2 miles then it dies. After I let it sit for about 10 minutes it starts up again. I am getting to the end of what I know to do. I have replaced the ECU, Main relay, most of the sensors, Fuel pump, and fuel filter. When I bring it in to get the codes for it all I get is sensor faults even though I have replaced them. Any ideas? I am going to let it run for a little while and see if I can feel any heat from any relays under the dash. I like this car but not sure what else I can do.

 

Hi fellers,I'am a newby at this getting on a forum so bear with me we just bought a s/hand 2000 mod Accent 3 door had it two days.All of a sudden were having fuel problems got under the rear seat to find a hose that came off and spewing fuel everywere, passable fuel line conector fault, a few loom ties fixed the problem yipie happy motoring once again

Yeah, I would have assumed it was the sensors too.
Did you replace the cam and crank sensors??
Those are your typical causes??

Is the idle steady??
Thinking it could be the IAC valve??
Or, maybe the in take plenum needs to be cleaned??

Wen the engine is running, do you feel exhaust coming out from the tail pipe?
Thinking it may be clogged??

Well, while the engine will not start, check for spark at the plugs??
When it is quiet, turn the key to the "ON" position and listen for the fuel pump to prime the fuel rail??
When cranking, do the injectors click??
Inspect wiring near turns and exhaust pipes for fray or shorts??

Have seen the wires going to the downstream O2 sensor fray and short out??

 

2000 mod accent, stop lights were staying on when the car is switched of so under the dash I went to see if the micro switch was working properly .looking at how it is supposed to work is; there is a tab off the side of the brake peddle there is supposed to be a rubber grumet in the tab off the side of the b/peddle whitch was not there a screw with a washer which did not do the job Ire placed it with a bigger screw ,problem fixed hopefully the start of some trouble free motoring
