1994 nissan pickup, runs rough. wont hardly run. cant find the problem.


It could be many different things. Check the vacuum lines. Check spark plugs. Check compression in engine, check fuel lines filter and injectors or carb. It's sounds like a misfire which can be caused by incorrect fuel, spark, or compression. And sometimes they run rough because vacuum pressure is incorrect or line is leaking. Start with the basics and go from there

Not getting fuel


which engine?
my guess, is it really dont start.
so the assumption is not getting fuel.???
got spark? (3 or 4 cylinders , 1.0 or 1.3L)?
compression at spec? 150 min, warm. or hot?
if test fuel works or runs for 3seconds , proving engine is ok but no fueling?
that and only that means not getting fuel.

the fuel pump on many cars does not turn on , until you crank the engine.
The ECU decides this, (software inside) and varies.
some run for 3 seconds key on. others, not. depends on country and year, and engine sizes, (only year was stated)

EFI rules to use:
ECU does not inject if spark is bad. BY DESIGN.
nor at wide open throttle ,cranking (bad TPS?)
all ECU operater the pump, when cranking and running.
so check the fuel pressure with a real gauge, cranking.
only that works.

4jg2 engine is not starting


does that mean it CRANKS robustly, if not? fix no crank or post that.
1994 trooper. (not starting wide open throttle to clear flooding>?)
is the 4JG2 is a 3.1 L (3,059 cc), EFI engine. V6.
this is 1 of 9 engines , used,
i think this 3.1 has a distributor ,
so does the cap off, rotor spin cranking, if not , the cam chain snapped.
next, is spark (i do compression first, but im odd that way, on old iron)
i check spark. i check it to all 6 cylinders using the time honored system. we all know, right>? with a fresh test spark plug, gapped correctly. got spark.
are you spark plugs old , never did the 60k mile tune ups, (repeats)
if the spark parts are old ,no car runs right.
you know the ,ole' cap,rotor,wires , sparks filters deal.'
the we check fueling.
i look at the spark tips, are the dry,? i try the test fuel test.
if car runs for 3 seconds on test fuel the engine fuel system is dead.
check fuel pressure next.


watch scotty do his magic.

1997 Mercedes c230 turns over fire once and die out


Have you tried first priming and purging the fuel lines of air bubbles prior to replacing the fuel pump filters? If you did and the engine still won't turn, otherwise you'll also have ignition problems. If the Toyota cars have 4 reasons the engine won't run, the Mercedes Benz has 101 reasons why the engine won't run, so to speak. So you start checking on the fuel pressure, fuel injection voltage or signals, spark ignition and all the way to the throttle sensors, crank pos senseor, ecu, or even the car alarm/immobilizer.... But first keep trying on purging all the air bubbles (with the Schrader purge valve on the rack) and make sure you have adequate voltage on your battery for high speed cranking, sometimes these will take a while at first.

My 1994 oldsmobile 98 regency won't start


Check fuel pressure,spark.If no spark possible crank sensor or ignition module.If no fuel pressure tap the bottom of the fuel tank with a mallet while someone is cranking the vehicle if it starts then you will need a fuel pump.Also if you have spark and fuel but the engine feels like it bucking while turning over,take a hair dryer and heat the coils up.you may have a bad coil pack.After they get warmed it night then start as the coil resistance changes.

My 1994 park ave, sometimes it starts, sometimes it wont, it does not matter if is is hot or cold, when it is running it runs smooth like there's nothing wrong. I replaced most of the fuel system, spark...


You have three choices. First, check the spark and coil system to ensure you are getting a spark. Pull off a plug wire from the coil pack and crank. Have someone watch to see sparks snapping off the coil pack. If you don't have any replace the control module under the coil packs.

Second, you may not be getting enough fuel pressure. Put a gauge on the fuel pressure test port. You may have a bad oil pressure sensor, located down above the oil filter. Check that oil pressure sender and make sure the connector is pushed in. The power to the fuel pump runs through the oil sender. If the engine starts and oil pressure doesn't come up quickly, the computer will shut off the fuel pump. Check this and you can also manually engage the fuel pump from the relay block down by the passenger feet.

Third choice, and it's a long shot, check the harmonic balancer and the crank position sensor. If the sensor is bad, the computer has no idea when to fire the spark plugs. A magnet is on the harmonic balancer and flys by a sensor to induce a voltage in the coil and tell the computer what position the crank is in.

You also may have a bad computer.

You can figure it out.

1994 Toyota Camry 2.2 engine. Car stalled and won't restart, cranks good, seems to have good spark. Can't hear fuel pump running when cranking. The pump will run when I jump the +B and FP terminals in...


I would check your fuel supply. You may have a clogged fuel filter not allowing fuel up to the throttle body. It is best to check before the filter. Be careful that the pressure built up does not spray all over. If there is no pressure and when you turn the key on nothing you have a bad fuel pump. If there is pressure you probably have a bad fuel filter or a bad fuel regulator. Wish you luck!!

1994 Chrysler LHS Starting Problems


it's either a spark or fuel fault , if there is spark after it shuts down it is a fuel fault. connect a pressure gauge in the fuel line, start the engine , note fuel pressure around 35 psi , stop engine , pressure should drop a little then hold, if not check pump return valve and pressure regulator , check fuel flow , if low replace fuel filter,
