Top 20 1998 Hyundai Elantra - Page 3 Questions & Answers

Have you checked your fuel filter and fuel pump to be sure that they are functioning correctly? That is the first place you should start.

P1611 =
MIL request signal circuit low input MIL-on Request Line

This code is set when the MIL On Request from the TCM (Transmission Control Module) has/had a problem getting the information to the ECU (Engine Control Module). In the 98 Elantra, there are two separate computer modules; one for the engine, the other for the transmission. (both located under the dash Driver's side. The diagnostic procedure specifies the wiring between the ECM & TCM be checked for any damage/defects. If none found, then replace the TCM with a new one to see if the problem (code) occurs again. If communication between TCM & ECM is corrected, you should have a ****** code related to the MIL On Request from the TCM (****** codes begin with P07 w/the next two digits (??) identifying the specific transmission component/malfunction).

Two on motor one front and rear. One on tranmission.

Fuel pump relay on the 98 Elantra is contained with MAP sensor. So test MAP sensor.

Don't let the car run out of gas. Fill the tank and run until the tank is half empty. Again fill the tank.
By driving until you run out of gas, you are letting sediments/dirt collected in the bottom of the tank to enter the engine. Rather they will block the fuel filter. Then gas will not reach the engine.
Clean the gas filter and your car will run fine.
The same advice again. Don't drive until the tank becomes empty.

The engine ID number is above the trans, printed on the block, below the head. There may be a emission decal under the hood showing a J1 or J2, if you call the Hyundai Parts dept with your VIN number they should be able to tell you.

1. replace your gear oil.

problem is caused by ignition timing. your ignition timing is overly advanced.

have a mechanic check your ignition timing. adjustments in timing are done in distributor, camshaft pulley, and crackshaft pulley.

take your VIN number to a locksmith, or your dealer, along with proof of ownership, and they can cut you a key.

You should have a drain plug on the Oil Pan for oil, the tranny requires you to pull the pan to drain the fluid, on on the radiator in order to flush the radiator and one on the rear end in order to check the rear end gear oil level. That is all.

Best advice, take the vehicle in to the nearest authorized Hyundai Service Center/Department & get an estimate. There'll probably be a diagnostic charge, but you'll finally get accurate information you need.

Unfortunately, they cannot be adjusted........they are things called hydraulic lifters...replacement only required

I would have the whole charging system tested with a Volt Meter before you change anything else. You can test the Alternator with a Volt Meter while the engine is running. The Alternator should be putting out between 13-14 volts, anything less and you have a bad Alternator. Check all Battery, Starter, Ground connections for loose or corroded wires and tighten or clean as needed.
