93 Maxima No start.
Hi all -
Ex-professional mechanic here, trying to help the neighbor lady out. She has a 93 Maxima 3.0-V6/AT that has had intermittent shutdown/no start since she got it; now it won't start at all. It died on her in an intersection and she cranked the battery dead trying to start it; one of her other neighbors said it was out of gas. Recharged the battery and put 5 gallons in it; spent some time verifying the fuel pump was operating before I discovered that this car doesn't prime the pump at ignition turn-on like most American cars. I have good fuel pressure at the rail, good spark, but intermittent/weak signal on noid lights at the injectors. I'm guessing Cam Position Sensor or Crank Position Sensor; which does this use for ignition trigger? I'm thinking it would be the other of the two since we have good spark which appears to be in sync with HV terminals in distributor cap; probably not a cam timing issue. Also, I've read here that later models (like 2000-2004) have an Immobilizer device in the factory alarm system which functions by shutting down the injectors, and that these can fail and cause no start. Did they have that on models this old? Any advice from those with more Nissan experience would be appreciated, Paul in San Antonio |

My only guess is that it has some problem with the distributors, that's probably the most common problem with that year Maxima.

I was afraid you were going to say that; so crank position sensor probably then... I hope it isn't a total clusterflop to do like the old Chevy V6s.

Not at all. The distributor it's very simple to replace, but very expensive. I suggest getting one from the junk yard.

Wait; I must be missing something here. If it gets ignition trigger from the Cam PS, which you say is in the distributor, and we have good spark, then the issue has to be Crank PS, or at least somewhere besides the distributor, right?

I just say that the most common with a no start situation with the 1993 Maxima is the distributor, which is the the one that includes the "Camshaft Position Sensor". As far as I know there is no "Crankshaft Position Sensor" on the 93 Maxima.
You should download the "Engine Control" section of the service manual for more information. You can download the section free from here: 1994 Maxima Service Manual - Loose Sections - Free with Registration - Nissanhelp.com |

93 Maxima No Start
The camshaft sensor is in the distributor !!!!There is not one for the crankshaft, you only have a crankshaft sensor in cars that don't have a distributor!!!

As for not in 1993 models; well, the Chilton's for this shows a Crank Position Sensor on the Emissions Controls Page for the 93-94; but now I'm thinking this was a transition year switching from the VG30E to the VE30DE, and of course I got the bastard child. I found a post referring to disarming the Factory Security with the driver's door key; I'm going to try that next time I can catch up with her. Can't hurt to try the stupidly easy thing first. If the CPS is in the distributor, does it use that to trigger the ignition or does it use a reluctor for the spark and modify timing with reference to a degree wheel like the old Mitsubishis used to do? Thanks, Paul |

It's similar to the Mitsubishi setup; in fact, some of the distributors were made by Mitsubishi! If you have a distributor, then you have the VG30E. The VE30DE was only used in the 92-94 SE models and had individual coil packs (or coil-on-plug) and a power transistor.
