Yes
2006 Suzuki swift fuel light Google Search

Under the hood, driver side, front side of strut tower, mounted in the relay panel. The cover may show which relay is for the fuel pump.

personal mods?

When starting/cranking, computer will activate fuel relay so that it will start. Once running there are fail safes built in - no oil pressure, bad signal from crank angle sensor or throttle position sensor, crash sensor activated (stops fuel pump) or even immobilizer faulty. Will it idle with Mass Air Flow sensor unplugged? Could be a broken wire or bad connector. Hope you have found problem by now! An auto electrician will find it very quickly.

It could be.
If you check the relay with a meter or test light and can confirm the relay is always sending power back to the pump, then the pump would be suspect.

its behind you glove box...no fuse no relay just a resister....probabley bad fan motor ? but check for 12volt first...

looking for a wire broken, and check not made negative contact that made blowing the fuse follow the power wire and when you found it fix the problem ok

Check the air filter and the sensors, they are clogged. You should also replace the oil and check the fuel filter, the lines and the injectors for damage, fine dust is a powerful abrasive.

get the wiring repaired correctly....sounds like they should have replaced the fuel pump relay and instead bypassed it and wired it to the wiper circuit?

Get to know the sister cars. The Suzuki Swift is almost completely identical to the Geo Metro and the Pontiac Firefly: the only differences were that the Metro and the Firefly were available in sedan form and the Swift wasn't. Also, no changes were made to any of these cars between 1995 and 1997. If you look for parts for any of these cars they will work.

Vehicles mentioned:
1995, 1996, 1997 Suzuki Swift
1995, 1996, 1997 Geo Metro 2/3dr
1995, 1996, 1997 Pontiac Firefly 2/3dr

In addition the only things that changed after 1997 were the bumpers and front turn signals (and that the Metro became a Chevy) so taillights for later Swifts/Metros/Fireflies should work as well.
