..

what a great question!
no year told, no country , no car told just raw engine
QG18 comes in many types QG18DD,,1999 to 04
QG18DE, 1999 to 2007 QG18DEN is the natural gas version?

lacking all key facts.
I go GENERIC (full bore)

the answer is super simple..
causes spark misfire. (and scanned PCM see P03xx errors DTC)

loss of engine horse power. and wasted fuel.
or engine dead. fully and no spark at ALL.

why worry it at all.??? if scans are clean this is it if CKP does not trip CKP errors DTC

must we guess all of these and if yes why?
and more,

The QG18DE is used in the following vehicles:

• 2000-2006 Nissan Sentra B15 and N16
• 2000-2005 Nissan Pulsar N16
• 1999-2002 Nissan Primera P11.144
• 2002-2007 Nissan Primera P12
• 2000-2006 Nissan Almera N16
• 2000-2006 Nissan Almera Tino
• 1999-2006 Nissan Primera
• 2000-2006 Nissan Expert
• 1998-2006 Nissan Avenir
• 1999-2005 Nissan Wingroad/AD van Y11
• 1999-2005 Nissan Bluebird Sylphy G10
• 1998-2004 Nissan Sunny B15
• every one sold in USA all scan easy as eating cherry pie !

the CKP and CMP sensors are the base line inputs for all spark and fuel injections and timing and timing advance of spark
if spark dies the PCM cuts all fueling dead( no crash&burns)

Go to auto zone they check for free and you will know what happened.

was the proper coolant installed? Poss wrong rad or thermostat?

Look at the bezel around the radio. It just pops off. If it goes up around the instrument panel, look for screws around there. Under the bezel, there will be screws to remove.

the radiator would not make the engine light come on, but the coolant sensor would..

In the USA, you need a scanner or code reader to retrieve codes on cars built after 1996.

have you checked how much fuel pressure there is.... your fuel pump may be going bad or it could be the fuel pressure regulator
