Check your o2 sensor harness. The harness if not properly secured will rub on the axle to a point where it rubs through the insulation of the wire & shorts on the axle causing the ECU fuse (20A) to blow. Repair the harness & replace the fuse & bada bing! You should be in business! Hope that works. IF NOT follow this K.I.S.S.

Keep It Super Simple! It never fails!

Why would a 2003 hyundai elantra have a hard start issue, fuel pressure bleeds off to 10 psi overnight from 50 psi?

There are many things that can cause this issue. If repairs have been done, you want to make sure you are using the original master key as the valet key wont allow the immobiliser to bypass and start the car. Fuel pump, bad fuel filter, injectors etc. If you have a check engine or service engine soon light on the dash you can scan the codes (for free at autozone advanced auto) and post them here. With these codes i will be able to tell you almost exactly what your problem is. ECU maybe? need just a little more info/background on the vehicle. We will get this resolved

2003 Hyundai Elantra Check Engine Light On

Take the car to Autozone or purchase a scanner and scan it for codes. Then do the repair and use the scanner or return to Autozone and have them turn off the light.

Suzuki esteem 2000 1.8l wagon. Check engine light on. Trouble accelarating in rainy weather. Any ideas? also how could i check the trouble code myself without obd device? Cheers!

Sounds like the moisture or the wetness from the rain is getting within the firing area. Try using Di-electric grease on the plug boots and coil pack. This prevents wetness from entering the firing area and causing diffused spark. If you have an Advance auto or Auto zone near you, they will usually check the code for you for free.

Hyundai elantra 2003 .the computer gives P0707 and the car jumps between shifts

There are some ecu updates that need to be performed by a dealer. Most elantras never develope a problem with this but some did, hyundai recognizes the problem and has several fixes that can be done by adding the updates to your cars computer, if it is still under warranty this would be done for free. If you are the original purchaser the ten year 100000 mile warranty should cover this. If not the original owner then you will have to pay for it. usually runs around $75. If you have a really cool hyundai dealer available they might hook u up for free.

2000 hyundai elantra car cranks but wont turn over just started fine 3 days ago

Did you scan for any trouble codes? Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps fix the problem.

2007 Hyundai Elantra has to be jump started. Battery is fine

from your comment,theres 3 things that can cause this,loose connection,weak batt.or something in elect. circuit that stays on after car is off and drains batt.,like underhood light,dome or truck light,what u can do is when u park car unhook batt. cable,make sure batt. is well charged,hook it up next day if car starts,its something that drains car! if it doesnt start,batt. needs replacing.i ruled out starter,dealer should have checked it to see if it was pulling too much amps,and that its easy to jump.

I have a 2000 Hyundai Elantra Wagon GLS, just had alternator replaced and check engine light came on on way home. Any suggestions?

The check engine light comes on because of an error detected by the car's computer. You need to have the specific error code read with a code reader/computer.
