SUZUKI Vitara Fuel Pumps

Description: There are two types of fuel pumps, mechanical fuel and electrical fuel pump. A mechanical fuel pump produces low pressure (3 to 7 PSI) and is usually driven by the engine and found on vehicles equipped with a carburetor. SUZUKI Vitara 1987 and newer all use electric fuel pumps, because of the introduction of electronic fuel injection. Electric fuel pumps produce higher pressure typically 10 to 50 PSI.

Purpose: The purpose of your SUZUKI Vitara fuel pump is to provide a constant fuel flow and pressure to the engine. A fuel pump pushes fuel from the tank and sends it under pressure to the injectors, which spray it into the engine’s intake manifold. The fuel pressure is kept constant by a fuel pressure regulator.

Maintenance Tips/Suggestions: SUZUKI Vitara Fuel pumps require no maintenance. Regular fuel filter changes can help extend the life of the electric fuel pump on electronic fuel injection equipped vehicles. A clogged filter can restrict fuel flow shorting the life of the fuel pump. You can also help prolong the life of the fuel pump by keeping as must fuel as possible in the tank. Since fuel cools the pump, having plenty of fuel in the tank helps keep the pump from overheating. A restricted fuel pump inlet strainer can starve the pump, causing it to overheat and fail. Buying your gasoline from a reputable dealer can eliminate this problem. Proper voltage at the fuel pump, and fuel pressure should be checked before replacing the fuel pump. Consult your service mechanic for proper pressure and testing procedures. Keeping your SUZUKI Vitara fuel system properly maintained is vital to your vehicle’s performance and fuel efficiency.

Failure symptoms: A failing or faulty electric fuel pump can cause various symptoms including a loud whine from the fuel tank area, hesitation when accelerating, and lack of performance and stalling.

WARNING: Ignoring these symptoms may lead to a total fuel pump failure disabling the vehicle.

AKA: Gas pump, fuel transfer pump, EFP

Location: SUZUKI Vitara electric fuel pumps are almost always located inside the fuel tank, but there are some vehicles where the pump may be located along the frame rail or mounted to the body near the fuel tank. The fuel pump has a strainer at its inlet to filter out fuel tank contaminants.

You can replace the fuel pump yourself.If you have proper part and tools available.In other case your regular mechanic is advisable to do this job. Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

Cranks, no start on 97 GMC van with 350 Vortec. Fired up with starter fluid


if it starts with starter fluid then its a fuel problem. check the fuel pressure and volume with a gage. these require at least 56lbs pressure to open the injectors and if the pressure is at 52lbs the they will not open. these use the pressure to open the poppet injectors and have a problem with the spider lines cracking and leaking fuel inside the intake. this is probably why it won`t start on its own.

Hard starting sometimes.have to spray starting fluid in throttle plate to start


If the pump relay is working and the pump runs when you turn the key on, it could be the check valve in the pump. The valve could be allowing fuel pressure to drain back into the tank when the engine is off.

Have a 2002 dodge stratus with a 6 cyl 2.7L engine. Was running fine then all of a sudden became hard to start. Switched the windshield wiper relay with the fuel pump relay. Started fine for one day then...


I would buy a fuel pump relay for that particular car. If that relay that you switched with the wiper relay isn't the same exact one then the fuel pump will not work properly. Make sure the right relay is in there. Could also be a clogged fuel filter.

I changed the fuel pump but the van still won't


And you know the fuel filter is good? Could be injector problem: just as a check, spray some starting fluid into the intake and see if engine runs a few seconds. If it does, it is a fuel problem. Check injector fuse, as a start. Check fuel pressure. Check injector circuit. If engine won't start with starting fluid, check if you are getting spark. Problem may be in the ignition system.

1997 voyager will start sometimes and wont sometimes


I suspect you have a failing electric fuel pump inside the fuel tank. To confirm this is the problem get a can of spray starting fluid from the auto parts store, when you experience the next no start spray the starting fluid into the air intake hose to the engine while a friend cranks it over with the starter, if it starts right up you likely have a defective fuel pump.

Slow start


You may have a fuel pump problem, next time it does this have a can of spray starting fluid around (about $5) and spray it into the air intake hose of the engine, if it fires right up you have a fuel pump problem or a wiring issue to the fuel pump.

Only in morning my car is not starting after sun comes up it starts with no problem.my office is 20 kms away from my home so i need sto start at 7 but it is not starting.


You may have a defective electric fuel pump inside the fuel tank, that would be the common issue for a problem like this. In order to replace the pump you must drop the fuel tank out of the car. You can verify the loss of fuel pressure by getting a spray can of starting fluid from any hardware store or auto parts store, when it won't start spray the fluid into the air intake of the engine, if it starts you have a fuel pump problem.

My 96 crown vic police interceptor, cranks won't start without spraying starter fluid.. the car won't start without spraying starter fluid into air intake hose to carb...


starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi
