I need some help, here is the issue. My dads maxima will not start. Before we forced it to start by giving it gas when we start, after a couple of mins then it would start. But now, its been a week now and it won't start. We can't figure out the problem. It is a 97 auto with 160k on it.

The car cranks, turns over but does not start.
We did the ecu test, followed on here http://vbxmaxima.8m.com/ecu.html
the codes it gives are:
01-02 mass air sensor
02-01 iginition signal circuit
02-05 idle speed control
06-03 cylinder 6 misfire
10-08 evap cansiter purge volume control.

What we have done already to diagnose the problem:
-Cylinder 6 has been misfiring for two months now.
-Starter has been replaced 2 weeks ago from autozone.
-Fuel pump and fuel filter both have been changed a month ago.
-crankshaft sensor replaced 4 months.
-EGR, IACV, MAF and TB all cleaned 4 months.
-Coil 6 changed 2 times in the last two months.
-Swapped all the coils around and they all good. The harness reads 11v-12v on all connectors.
-Coil harness 2 and 5 give no spark, the rest of harness, 1,3,4,6 have spark.
-Spark plugs have all been cleaned.
-Disconnected the maf sensor and still no start.
-We used my 01 max as a test car. we swapped out 3 sensors from my 01 and used them on the 97 max. 1.the camshaft sensor, 2.crankshaft sensor near the crank pulley, and 3.crankshaft sensor near the starter.
-The injectors are good, they all spray gas, as they should.
-No blown fuses either.
-Swapped out battery as well.
-Swapped the ecu/ecm from a used 97 maxima, still made no difference.

I can't think of anything else to do. What can the problem be? my concern now is that there is no spark from 2 and 5, while 6 is misfiring and it will not start.
I've read so many threads and sites, tried everything I thought can help, but still can't get it to go.

 

have you tried adding ground wires? i ran one from the tranny right to the neg terminal that has help many many people including myself its like a 3-4 dollar 4 gauge cable

 

so you've been misfiring for 2 months, and didn't fix that?

 

Its my dads car, he doesn't drive much and doesn't have the time to fix it, so I'm helping him now. you have any advise to fix the misfire?

 

check the fuel pressure regulator make sure its holding pressure pull the vacuum line off see if there is fuel in it if there is get a new one if there isnt you can pinch the line after teh regulator let the pressure build up if it starts replace the regulator if not rule it out

you can also swap the starter rely with another of the same color if that works replace the rely let us know if that worked

and here is a pic of where i add a ground

 

might have a bad coil harness. Seems like all electrical issues to me

Rough idle: Rough running engine accompanied by check engine light may require revised powertrain control module. (1997)

Rough idle: Several problems (no-start, no A/C, rough running, etc.) can be traced to broken wires in the engine compartment where the harness bends near the right strut tower. (1995-97)

 

where is bolt for the ground located? driver side or passenger side. is it ground to the battery or the chassis? I'll try the vacuum lines and see if it hold pressure, I sure it does but will double check. thanks

 

it could be electric since only 2 coils aren't getting spark, but they all have 12v at the harness. I have to test the ohms next from the harness to the ecu.

 

that is on the driver side... its on the tranny i ran it right to the neg battery post youll have to remove the air scoop thing to get to it

as for the fuel pressure regulator's vaccum line your looking to see if there is fuel in it

 

yeah not having good grounds can cause all srots of weird things to happen

 

whats ground wires??
