My 98 Deville will not stay started. I chafed the fuel filter and it ran find for 20 mins and now even putting gas in the intake will not keep it started and keep tryin to start it runs down the batti

sounds like a fuel pump pressure issue..need to pull the line up front and check for fuel pressure..replace the pump if bad, money an issue? get a junyard tank like I did,,35 bucks and put it on..also check the throttle body assembly for operation..should spray gas into the intake while cranking on it(in spurts) if not replace the tbi unit with a salvage part..repost please

No gas pressure, gas is in the tanks but no gas in lines. Truck will not fire. I do have spark.

if you are not getting gas in the line from the tank -- then I would say that you have a bad valve/regulator. remove and replace.

It starts when I used fuel starting spray, then it quit when the starting fuel is gone.

Bad Fuse,pump relay,Fuel filter,weak fuel pump,pluged fuel filter in the tank.bad pressure regulator,check to see if the pump runs in the should here it run while you crank the engine. if you can then check the should be open,not restricted.then check fuel pressure,at the fuel rail,with a guage 36 to 40psi is normal. Any less pressure will give poor performance.Check to see if the pressure regulator is or has ben leaking gas into the vacumn line to the intake manifold,if you can see smell,or detect any raw gas i would suspect a faulty pressure regulator.And it may be returning the fuel pressure back to the tank instead of controlling the fuel pressure to run the engine.

Car starts fine but when accelerating sometimes dies

Hi, this is poor fuel circulation that is caused by a dirty or clogged fuel filter. i recommend changing the filter and replacing the pump as well. you can also add some fuel tank/injector cleaner. this solution will scrub the intake and fuel tank and lines, getting rid of those harmful deposits that tend to be in our fuel supply.

I have a p0441 fault on my 2003 dodge neon. i changed the canister purge solenoid and the light went off for about a month and just came back on what could cause this?

Evaporative Emission Control System Incorrect Purge Flow The "EVAP purge flow" faults are issues between the carbon cannister and the intake. The EVAP leak detection generally concerns the fuel tank to carbon cannister plumbing. A little background. The EVAP or evaporative emission system is a control system to keep vapors from evaporation in the fuel tank from getting into the atmosphere. The fuel tank is not vented, but rather the vapors are piped to the carbon cannister (usually located behind the pass. side front wheel) where the charcoal element absorbs the vapor. This is actually a vapor "storage" device. Under certain engine operating conditions, the ECU activates the Cannister Purge Valve (N80) which opens and allows the engine vacuum to **** the fuel vapors back out of the carbon cannister. This purges the vapor, allowing the cannister to absorb more vapor. This evap system has been on vehicles since the '70s. As part of the OBDII standard effective for 1996 cars and newer, it was mandated that leaks in the systems must be detected and reported as a fault which will set the Check Engine Light (CEL). To detect leaks, the system is pressurized by a pump so that leaks can be detected by a lack of appropriate pressure in the system. If there is a leak, such as a cracked vent hose, loose (or leaky) gas cap, poorly installed or defective O-rings on the fuel level senders on the fuel tank, etc. a code will be set. On the cannister to intake side, leaks are detected by deviations in the idle control system. If you have leaks in the lines from the carbon cannister to the intake, intake leaks, a defective purge valve, etc you will often get purge flow faults. My first recommendation is to closely inspect all the small vacuum lines connected to the intake manifold. The corrugated plastic lines are often the culprits, as well as the fabricate covered vacuum lines. Also consider replacing the gas cap.

95 Chevy Caprice won't start unless I disconnect the fuel line.

Fuel pump can also cause this problem, You find out if fuel pump is faulty by energising directly fuel pump, and checking fuel pressure.

Check also the fuel line, starting from gas tank, often oxide and dirt from tank can obstruct the hose. Disconnect fuel hose and blow air into it .

Check also air filter and air intake.
