The only thing you can do is drive it until it is really low on fuel, and put some good gas in it. DO NOT FLOOR IT. It can cause pre-ignition, and possibly hurt the motor.

Difficult to start, then when it does the clock resets.


You have done a lot...how about the fuel injectors...and bad/old gas in the tank...has your car been parked for awhile? I would add 2 bottles of liquid HEET to disolve the sludge...and add 2 bottles of gas tank fuel injector cleaner...I like the Lucas Oil
Brand...Hope this helps.

1998 Suzuki Esteem ran out of gas. Still won't start after putting in gas. Is there a way to prime it.


putting gas where?
gas tank
or doing the Test fuel procedures?
is this a barn find/ field found car, or it ran perfect last week, and DD for months. (daily driver?) all this maters and is unstated.
1.6L or 1.8L engine, G16 or J18 suzuki enignes? major different they are.
with old engines, we do this and win every time.

all FUSES good, (EFI and spark fuses up to 3 or more)

1: compression test, sparks out , wide open throttle. warm to hot engine.
180psi on all,, good, if like 90, the timing belt slipped. if J18. we have
3 folks now on our forum that managed to slip a chain (they ingored huge noises from engine,,,, amazing)
2: spark got good on all 4 cylinders. and timed right not guessed at
using a real tool called a timing light for 20 bucks.
3: with fuel pump relay pulled i test engine on test fuel.
runs for 3 seconds, each spray and SOUNDS good.
ok it does that.. (this avoids flooding issues)
4: i put back the fuel pump relay.
and it dont start. i check for injection,
i find all injectors, dead.
the ECU is cutting injection,
i connect scan tool and see the CKP DTC errors , the CKP is dead
or CMP on G16. dead. the ECU reports them cranking only, on a dead engine.
the ECU will cut fuel if it seen spark dead.
the ECU will cut fuel if the TPS sensors signals wide open throttle cranking
i checked all that and its good.
i find fuel pressure a 0 , cranking, (one more cheap tool)
i find 12vdc good to pump cranking (a 10 buck meter at walfart)
the pump is bad. no the wires are corroded. at the pump line....
super common on old cars.

this is 1 example path of 100s.

My Chevy 2500 p/u will only start and run when I pour gas in the carb...if I kill it for 2 minutes , I have to do it again to get it started ...uhg..frustrating !!! One guy told me it was a spider sumthing...


Lets start with terminology. I am assuming the truck is newer than 1987 so you would have fuel injection. No carb.
If it is a vortec engine, either a 4.3 or larger, and built after 1993, it could have central port fuel injection. That style uses one injector and a spider of lines that go to each intake port. This is inside the upper intake manifold.
Vortec engines require more fuel pressure than engines with port fuel injection or throttle body injection. So the first thing you need to do is check base fuel pressure before and after you crank the engine. You'll need a pressure gauge to do it. Normal fuel pressure at idle for a port injected engine is 35psi and 60psi for a central pfi system.

2000 nissan maxima engine hesitation problems


Has your Nissan sat for a period of time? If so, could be dirty gas...try adding 2 bottles of Heet gas line antifreeze and injection cleaner..also as this works, be sure not to let the gas level go below 1/4 tank...If needed check air filter dirty...throttle body dirty...Hope this helps.

Black smoke and high gas comsumption


This sure sounds like a "rich" condition. Meaning the engine is receiving too much fuel from the fuel injection system or the carburetor, depending what type of fuel delivery system you have and the year of the vehicle. A rich condition most always causes excess carbon (black smoke) and high gas consumption. A common cause of this on later model vehicles with fuel injection is a bad fuel pressure regulator allowing too much fuel to enter the throttle body. Many pressure regulators are connected directly to the fuel rail running along the topside of the engine. It's about 2-3 inchs round and has a vacuum port on top of it. If it is easliy accessable, pull the vacuum hose off of it and see if the engine idle speed stays the same, also check for any unwanted fuel inside the vacuum hose. If those 2 conditions exsist, chances are you have a bad fuel regulator.

Carbureted vehicles are another story. They have a float and a needle & seat assembly inside which sometimes get stuck or dirty, allowing too much fuel to enter the engine. Both of these parts are deep inside carburetor and are best left to a professional technician to diagnose. One last thought. A bad oxygen sensor (O2 sensor) will sometimes cause a rich condition. But if an O2 sensor goes bad, it is usually accompanied by a "check engine" light coming on.
If your check engine light is not on, it's probably is not the sensor. Hope this helps some, good luck..

Why si the check engine light on on my 2006 Chevy


Tighten your fuel cap 3 times to make sure its tightned. don't push it in when you tighten it. Use Fuel injection cleaner like once a month... You may have gotten bad gas. Don't use 100 percet gas. Use gas with ethenol... you get better gas mileage. I go through 3-4 tanks a week. I use the 87 octane and I put Berrymans Fuel injection cleaner in once a week. I don't know about your hesitations though I drive a 5 speed

2001 mercedes benz ml320 stalls


It could just be the fuel injection tips have black tar build up. But, this sounds like the typical, 1980's problem with people who used to put cheap gas in their mercedes. You get gunk buildup in your gas pump. When the car is hot, the gunk expands and you get no gas flow. First try about 4 applications of puting a bottle of good fuel injection cleaning fluids in only half tank gas and let it run almost dry. If you don't see a substantial change, don't even waste your time playing with it trying to clean anything, those are only agrivating band aids on a broken leg. Change the fuel pump! your car should be as good as new.

I have a 93 buick lesabre and it cuts off after starting it or will cut off while driving . this problem did not start until i recently put some fuel into it while the store's fuel tanks were being...


It's probably just a coincidence that your car started acting up after getting gas but just in case add a couple bottles of Heat or an Octane booster that cleans your fuel system out.
Is your check engine light on??
I've heard of simliar problems happening and it was the crank sensor that was bad. Go to your local parts store and see if they can scan it for fault codes, I know some around me that will do it for free.
