Question about Cars & Trucks

1 Answer

My daughter has an 03 Hyundai Sonata and recently I replaced the fuel pump, timing belts, and the crankshaft position sensor. The same day the work was complete she took it to fill it up with gas and told me that the fuel gauge wasn't working. The following weekend I checked the connections to the fuel pump thinking that was the problem b wasn't. A few minutes later my daughter went to leave and it wouldn't start. I fiddled with the wires to the fuel pump again and it not only started but the gauge started working. The following day i pulled the pump out thinking the bad connection was there and when I put it all back together it won't start. Pump is working, gauge is working and I'm about to lose my mind trying to figure this out. HELP. n dn't startnd its latut it on sensor

You probably have a bad fuel relay switch. It is located in the engine compartment in the fuse box. It costs about ten bucks and takes 2 minutes to change. I hate to say it but you probably didn't need a new fuel pump. If the relay is not the problem then it will be your fuel pressure regulator about $60. This part will affect your fuel gauge and cause intermittent starts and stalls or a no start. If your car sits for awhile the pressure will fall off and the car will start again but will not run well and it can stall out at anytime and not re-start.

SOURCE: 2004 1.8l nissan sentra what now? not battery or fuel pump/filter

Check your catalytic converter. If you are over 80k miles, these devices will wear in stages. The first stage of wear is slower gear change at cruising speeds when approaching any type of incline. Second stage is the engine light will reveal a faulty oxygen sensor. Because the converter is basically a "filter" built into the exhaust system, it wears by slowly clogging, which leads to no starts, no power, and sometimes a blown head gasket. If your mechanic removed the oxygen sensor before the converter, theres a strong chance it would start right up.

SOURCE: 1993 Jeep Grand Cherokee Fuel Pump?

Between 100-140 thousand miles the fuel pumps go out on the 1993 cherokee. Its a fact. All parts are manufactured with the knowledge that it will last for a specific period of time then it dies. The relay switch was helpful for a brief while because there was still some juice in that pump, but now that it is gone it is gone.

If you don't see the fuse box under the dash in the driver leg area or beneath the radio check for a covered box under the hood. There should be a fuse spec guide on the lid of the box that tells you where specific wattage should go and for what purpose. But, your fuel pump problem will not be solved by a new fuse.

Replace timing belt and balancer belt now have no spark on a 2001 Hyundai sonata 2.4


Make sure all electrical connectors are in fact connected, especially on the transmission side of the engine, under the air boxes and ductiing. Signals from the crankshaft position sensor and camshaft position sensor(s) are what tell the ECM to fire the spark plugs and fire the fuel injectors.

2004 hyundai sonata code P1372 segment time incorrect


In the factory manual this code translated to a erratic signal from the Crankshaft Position sensor. I would check the connector to the sensor first and the wiring as well. The sensor is located above the crankshaft front pulley under the timing belt cover.

I can't find the location of the crankshaft postion sensor in my 2000 Hyundai sonata


My online Sonata manual shows these possibilities, but does not identify which applies specifically to 2000 Sonata.
Also, when you talk to the dealership parts counter, you'll need to know whether your 2000 Sonata is (a) 4-cylinder 2.4L MFI DOHC engine, or (b) 6-cylinder 2.5L MFI DOHC engine.
Its easy to tell - just count your spark plug wires.

-- begine excerpt from 2000 Hyundai Sonata Repair guide --

The crankshaft position sensor is located next to the flywheel.
The crankshaft position sensor is located next to the flywheel/torque converter.
The camshaft position sensor is located on the engine near the timing belt cover and under the upper radiator hose.
The crankshaft position sensor is located on the driver-s side of the vehicle, down by the lower radiator hose.
The crankshaft position sensor is located on the engine near the crankshaft pulley.
The crankshaft position sensor is located at the front of the engine near the timing belt.

I have a hyundai sonata 2000 it is 2.0 16valve wont start


Firstly, what's a TDC sensor?.. the crank position sensor? If so, on the four (4) cylinder, it's located behind the timing belt cover at the crankshaft.. if it's the 2.5 V6, it's located behind the LH exhaust manifold on the engine block.

2000 Hyundai Sonata wont get spark


OK!... Tell you STRAIGHT UP!.. this is a GUESSING GAME online. Fuel Pump failure 'apparent'?.. Did anyone VERIFY it was the fuel pump? Unless you guys know what you're doing, you need an EXPERT's EYE and BRAIN on this one -- it could be almost anything!.. Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there... otherwise it's a GUESSING GAME! There are too many possible causes which prevent a SPARK (i.e., fuse, ECM, Wiring, ignition failure sensor, bad CKP (crank position sensor), out of time, etc.
