Not starting Hi I have a 1992 Sonata the engine turns over with good speed but wont start fuel pump ok, turn over ok,no spark. my suspician is a sensor if so could you tell me what it is and were it is located. Thanks Dave

Have a load test preformed on the battery.

That could be it but it couldbe coilpaxks or your distributor rotor button clogged fuel filter do you have a chexk engine light

Make sure battery has a full charge. If it cranks good but won't start, check the basics. Have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. I looked at info for the 3.8L engine, 35--40 psi. Also, after you build fuel pressure, turn off the key, see if fuel pressure holds for a bit? If the pressure drops like a rock, check for fuel pressure leak. Check the vac line for fuel pressure regulator, if it has gas in it, the regulator is faulty, or a leaking fuel injector. The pressure could also drain back through fuel pump.
Also, check fuel injector pulse, engine cranking. Any applicable trouble codes?
Smell of the crankcase oil dipstick, if it smells like gas, either you don't change oil and filter very often or the engine is running very rich for some reason.

could well be the electronic fuel pump, I am having the same problem and that is what i have been told the problem is...

I had a car a couple of years back do this to me, it was the crankshaft sensor. It will not fire at all if it is bad. Luckily the part is really cheap.

need more information:
1. does the motor turn over when cranking, and just
won't start?
2. if not, when you turn the key to on position can you hear the fuel pump kicking in?

Check the starter relay.

hi is there fuel getting to engine?any vapour coming out exhaust?sometimes glow plugs not working can cause this.try a squirt of easy start into air filter.NOT MUCH!!READ INSTRUCTIONS.HIGHLY FLAMMABLE.then start car for about 10secs.get this from car accessorie shops.if it fires on this its highly likely glowplugs not working or fuel pumptiming out.its hard to say without seeing the car

Ok this could be several things you could check:

No gas: First of all, make sure it's got gas. I don't care if the gauge says you have some, they're known to fail.

Now, if it's fuel injected, have someone turn the key to the "ON" position. You should hear the fuel pump prime the system with a small whirring. You may not be able to hear this unless it's quiet outside. On most Beemers the fuel pump is under neath the car along the frame rail. Mine used to be on the driver's side.

If the fuel pump is in the tank, simply unscrew your gas cap and stick your ear up to the filler neck, have someone turn key. Hear something? That's your fuel pump. If you don't hear anything, take to a mechanic, because it'll get complicated.

OK, if you got gas, then you can check your pressure by using a fuel pressue gauge. You may have to "T" this into a fitting on the fuel rail, or it may already have a port. If so, plug it in, turn the key, and see what it reads, If nothing, or really low, then fuel pump may be bad.

No spark: Pull a plug wire, then pullout a spark plug. Put plug in wire, now hold wire WITH PLIERS against a bolt or other conductor. Have someone try to crank. Did you see a spark? Well you got spark. If not, take to a mechanic.

If you have spark and gas, then it should run, UNLESS:

Timing belt broke: Unscrew your oil cap. You should see mechanical thingies in there(camshaft, vavles, etc). Now stand back a little. Have someone turn the engine over. If the engine turns over and nothing moves on top, then that's bad. Take to a mechanic. Then go rob a bank. You'll need it.

Good luck! Leave comments!

Hi,check the fuel pump fuse and the fuel pump relay,if this is ok check for fuel presure, good luck........ C1
