No start! No spark! No check engine light coming on when key turned on
Asked by SE007 Mar 11, 2017 at 11:34 PM about the 1998 Nissan Pathfinder 4 Dr SE 4WD SUV
Question type: Maintenance & Repair
I have a 98 Nissan Pathfinder SE 3.3 V6
Automatic 4x4 and it won't start. No spark
No check engine light when you turn the key
on and no connect to PCM/ECU when you
try to read the codes with a scanner. All the
fuses and relays look good and wiring. Any
ideas before I start tearing It apart looking
for an open circuit to the ECU/PCM?

I feel that Nissan is avoiding this question cause no one seems to have the answer, I paid twenty buck to ask the pros at nissan why is it that all i did was change my battery and now I get nothing! No dash,dome,horn and definitely no start! But no one seems to know how to solve this issue that so many customers are having!! Idk maybe nissan yanked all of us on this one!!

Check 1st that the ecm is coming on. Some cars have a main relay that is the 1st place when you turn on the key that the key joins the battery voltage to the relay. Then the relay distributes the battery voltage to the ECM and or icm. Your 1st trace is from the ignition key area which is the ignition switch. Think about what you do 1st! You stick the key in the ignition and when you turn the key it positions the ignition switch to join the 12 volts from the battery to whatever your ignition switch is wired to directly
It's the ignition distributor I just went through intermittent spark on my 2000 Nissan Pathfinder SE 3.3 all of the components for ignition are in it
i replaed everything entire dist. cranknsensor ...ecm relay still no spark
