Ok guys I was here before and tried to figure this one out but i'm hoping somebody else might know now.

My 95 SE won't start. It has a new starter, good battery, all new Cam Position and Crank Position sensors, fuel pressure tests out right, coils all have proper spark, new plugs yada yada yada. Now heres the thing that gets me and everybody else. IF you can get it running (5 times in a year) it runs like a champ. Has all sorts of power and good pick up. But once you try to restart it won't go, and the only way to get it to go is to take out the plugs and replace them with dry ones. They get soaked at some point along the line, either during starting or while running. I can't solve this and 3 mechanics including a nissan dealer's head mechanic (on his own time) have swung and missed. I know you all want the codes to try to figure this one out, but I don't have access to them right at the moment, I can tell you that its kicking a bunch of evap codes, and o2 sensors, most of which I am guessing stem from the fact that the car is running richer than rich. So if ANYBODY knows what the h3ll is going on here, please help me out. I've had to buy another car just to get through because of this thing and its not looking like that car wants to keep its job much longer. Throw out what ya got and I'll be happy to try it. O BTW the motor does turn over, just won't fire. Thanks in advance for any help.

 

Ignition switch, a common failure and it's the only thing you haven't replaced.
Also make sure the ECCS relay is working correctly.

 

Tom - he says the motor turns over, just doesn't fire... I'm not sure how it can be the ignition switch?

 

could it be bad coil, or coil packs? or maybe injectors are bad and spraying too much fuel?

just a guess as i have never experianced it... but good luck

 

Stop replacing things and find the problem. Have you measured the fuel pressure? Also, I'm pretty sure our ecu's have a 'wiggle test' function, might want to read up on that. Also, if you quickly floor and fully release the gas pedal twice while cranking, the ecu will vary the injector pulse width's to go full rich back down to full lean, try that next time you start it. ((I'm not positive if our car's due this, but it is a little known fact that 95% of efi cars have this feature))

 

And don't overlook a bad ground, or bent prongs inside a connector.

 

Engine Coolant Temp Sensor????

 

OK, fuel pressure test out fine, coolent temp sensor has been replaced. I don't know what a "wiggle test" is, anybody? Where and what grounds should I be looking at? ECCS is? It sounds familiar from my past battle that solved nothing, but mabey not. Anybody know of this flooring the pedal thing? If it would work i would be all for it. O and its not like I am just replacing things for the fun of it, all of the things i have replaced are legitimate reasons that the car wont start and the ECU indicated I may need. Thanks again guys

 

any help here guys?

 

You need to pull ALL the codes and report back... the answer might be right there.
