I have a 95 Nissan PU getting fire to all plugs,fuel pumping up to & out of fuel filter but will not start.?

Question

Getting fire to all cyls., fuel pump is running, pumping fuel out of fuel filter but will not start. Tried to self diagnose ECU but battery had been removed so I came up with code 55, Normal (nothing wrong). I know I would need to have it running to retrieve actual, accurate codes. What can be wrong? fuel pressure reg, injectors, distributor, ECU, wiring between distributor & ECU ??????? I should mention the truck is a 4 cyl 4x4 and also has been sitting for over a year. any help, Ideas will be greatly appreciated.

Poured fuel into throttle body-engine ran for about 30 seconds, stopped. Repeated this and now it just turns over with no attempt to fire. Pulled no. 1 plug, turned it over and it is getting fire out of the plug (repeated this for the other 3). Using a battery out of another car so when I removed the battery (after it ran for 30 sec.) I assume it cleared the codes and thus I'm getting code 55 (OK/nothing wrong). I'll try all the replys I received and maybe I can figure it out. Thanks to: wayne g, john paul, james s and 72 olds cutty. I really appreciate all the help. Thank You, Rick L

PS: I realize that mode 3 is where the main codes are but am I correct that if battery is removed, all modes of codes are lost ??? Also, does fuel go stright from the fuel filter to the fuel rail to injectors or is there something in between (such as fuel pressure reg. etc..)??? I know very little about Nissan's. I had a 87 300 Z, V6. It was doing the exact same thing. Only difference between the 2 is the 300 Z had a hot battery at all times. I read the codes(red & green lights) and replaced the mass air flow and oxygon sensor-fired right up. Does this 95 4cyl PU even have a Mass Air flow and if so, where is it located?

Answer 1

Have you considered the starter at all. A corroded Solenoid. Bad fuel perhaps, you said it's been sittin' for a year.

Answer 2

Does it act like it wants to run when fuel is introduced to the throttle chamber under the air cleaner? Sitting for over a year? Probably because it won't start. Next test are the fuel injectors squirting? No the engine does not need to run for codes to be flashed red and green. Mode 3 is where the codes live, other modes are switch tests and O2 sensor tests. Those D-22 trucks are just about bullet proof look along the distributor some times the wires rub on the A/C metal line and short the ECM cam posistion signal.

Answer 3

I wonder. Could it have jumped time? To check, Remove
the No # 1. spark plug. make sure the No # 1 plug is
ready to fire. With a slim screwdriver down into the spark
plug hole make sure the piston is all the way up. You can
tell if its all the way up by moving the fan back and forth. If it
has a fan clutch or the built slips then you need to turn it buy
the main pulley wheel on the crank. If you cant get it to fire at
the same time the piston is all the way up the timing chain
( or belt ) will need to be replaced . There are marks that
must be lined up or you will have the same problem as now.
If its not the timing I would like to know. Good luck.

Answer 4

there are some fusible links on the positive battery cable that send power to the fuel injectors. You can test both end of the fusible links for power and also you can check the connector on one of the fuel injector for battery voltages. Remember the fuel injector should always have battery voltages to one side of it the computer control the ground pulse withe.

Answer 5

Have you made sure that fuel is at the injectors? Then you would know which way the problem is. If you have fuel at the injectors, then your problem is before them. If fuel is reaching the injectors, then your injectors are the problem.
