There are four fuel injectors. If your looking for replacements, try www.fiveomotorsports.com I own a 96 paseo and they have a set of four for around $160. Check for availability. As for the difficulty of this repair, I have not done it yet on my vehicle. The above website sells re-manufactured injectors. If you are interested in buying brand new ones, expect to pay $100 or more each.
fairly easy
There are many little steps when removing the injectors, I would recomend a haynes manual. It's not hard to do, but better if you have the pics in the book to go by.
Probably the fuel pump. Or the injectors.
There was a recall on the fuel injectors on the M30's due to leakage. Just take it to a dealer and they will replace the injectors for free. You'll even get a loaner car while they work on yours.
Fuel injectors eventually wear out or get clogged. In these case, you need to?æreplace the fuel injector. Failure to change it can lead to bigger problems like poor fuel economy, hard starting, rough idle, and sometimes, having a fuel smell inside the vehicle.?æ
It could be a number of things, in line fuel filter clog, fuel pressure faulty, it also might be electrical related, ie electrical to Fuel Injectors, partially blocked Fuel Injectors. OR it could be that you have a blown head gasket and your engine is loosing compression. that's what happened to mine.. =//
Bad as in dirty would simply supply unfiltered fuel to the injectors resulting in misfiring,hard starting and uneven and generally bad acceleration.Bad as in faulty could lead to fuel starvation,motor won't start, rev,cut out etc. no, supply unfiltered gas to the injectors? its a restriction, meaning no or very little gas to injectors, low or no fuel pressure
loosen the fuel line and if fuel squirts forcefully out the pump should be good,but it's really hard to tell pressure wise if you have fuel injectors they need a specific pressure to run.
Carb.? Choke not working or not adjusted properly/ Fuel Injected? Perhaps loosing prime (bad injectors)? Weak fuel pump?
underneath the plenum which sits on top your intake manifold. as far as being hard to (JUST CHANGE) not really, more time consuming then anything and a bit expensive so be sure you need to replace them at all.
How hard is it to change a 2000 Nissan maxima fuel filter
I believe it is a bad fuel injector or a gasket on one of the fuel injectors. Check all of them. They are right on top of the engine and not that hard to check.
