My 2007 Suzuki forenza will turn over good but will not start fuel pump new but when you turn switch on can't hear it hum gas getting to injectors reckon it could be anti theft security please thanks

Is there a SECURITY light lit on the dash ? All anti-theft systems warn you some how if a problem is present ! The fuel pump only comes on for two seconds with key on ! When cranking the engine over if a crank pulse is see by the engine computer it will energize the relay turning on the fuel pump ! You have to check the fuel pump electrical circuit from the fuel pump relay !

I have a Suzuki Grand Vitara and the power to the fuel pump goes from 12v to 2.87v within seconds of turning it on and so pump not getting enough power to run the fuel pump. Is this normal?

IN the fuel systems there are fuel pressure sensors and relays . f the fuel pressure is at the set limit then the sensor tells the CPU and it shuts down the relay or fuel pump so that it is not operating under pressure all the time . IF you are not experiencing problems with the engine performance the I would leave it alone for now

Would a faulty electric fuel pump relay be the reason there is no power going down to the fuel pump in a 2002 suzuki grand vitara 2.0 rhz diesel engine

To test fuel flow, have a 2nd person stand over air filter (air filter housing open) with a can of starting fluid in one hand. Don't give any throttle, then 2nd person gives 1-second squirt into air filter while you're turning starter motor (no throttle). When engine catches, immediately give one third to one half throttle. Just before it dies, 2nd person should give another short squirt of starting fluid to keep engine from dying. If throttle won't keep engine running and only starting fluid keeps it running, then yes, no fuel is going through fuel lines. Either its a fuel pump issue or maybe there's restriction because of clogged dirty fuel filter. If it starts but runs rough and has black exhaust smoke, then its clogged or dirty fuel injectors.

My Suzuki areo fuel pump is not kicking in and making buzzing under hood even after changing pump.Already checked relay.

i see you are guessing?
did you check all engine related fuses? that be first.
with a $20 DMM volt meter , the guessing ends.
the electrics form 2 paths,
1: power
2: ground
if either are bad, the pump fails. (suzuki love to do this)

when you turn the key, the ECU/PCM , energizes
the fuel pump relay,
if you have no power to the relay the relay will be dead.
the relay then passes pump power to the pump, on the pink wire
on most suzuki's state side (no location stated)
the pink wires goes hot (12v) for 3 seconds each key on.
if not the relay is bad, or the power to it is bad or the ECU is bad.
if you lose ground to the relay , the ecu or the pump. the pump
will be dead.
using a voltmeter allows you to find this simple failure.
lets pretend the pink wire is hot.
you key on, pink goes 12v , for 3seconds but the pump is silent.
1: the pump has 2 wires , not 1.
one or the other is open.
2: if you see 12v on the pumps ground wire for 3 seconds key on.that means the pump ground is dead open.
the voltmeter will not lie to you , use it and find the problem easy.

I have a Suzuki Jimny the engine turns over but will not start. i have tried the plugs and get a spark there is fuel in the tank

It is in the tank, on top of the tank. It must be dropped to access the fuel pump. If You turn the key forward till your auxiliaries come on, you should here the fuel pump if you listen with your ear to the gas pump spout. It will make a dull whiny noise if it is working.

Checking power to fuel pump 1998 gsxr750w

Yellow and red wires should be your power wires, the others should be ground. Check for both. You may need to turn it over a few times to get the pump to prime.

Suzuki Boulevard Weird Noise

Its probably your fuel pump, but the noise should stop after a couple of seconds when its primed. Might want to have it checked.

91 sidekick engine won't start, fuel pump relay replaced and working,fuel pump not running

Check for power at the fuel pump, I've seen these have a bad connection for the fuel pump in a connector behind the left rear taillight. If that connection is good and you have power and ground to the pump when you cycle the key or crank the engine, then replace the pump.
