Hey all, I'm new here, and I'm trying to figure out my mother-in-law's Infiniti J30. I own a '94 Nissan Pathfinder with the VG30 engine, similar ECU and codes, etc., and I've turned wrenches on that for 10 years, so most of it is the same, yet I'm stumped. We borrowed the J30 while they're out of town for the winter, but after a week or so of driving, I went to start it in the driveway and it just turned over and over. It has 165K miles on it. It spun pretty fast from what I'm used to in the Pathy, and compared to the few times I drove the car, so I immediately thought dead timing belt and/or no compression, and it didn't have any signs of anything weird when I parked it. But then again, it was kinda similar to when my fuel pump in the Pathy was dead. I found the ECU in the passenger kick panel and pulled the codes, and I'm getting a code 51, which points to the fuel injection circuit. I've never messed with that stuff, so I wanted to post up and get feedback. I figured if it was really something with the fuel injection, like a bad injector or seal, it would just run really rough, but this thing won't even make an attempt to cough, sputter, or start. I searched and read some stuff that spooked me, where some people spoke of similar things after changing a timing belt (I think its been a while, though my father-in-law is good on maintenance), and it jumped a tooth, or possibly the belt broke.
Anyways, any thoughts? I don't have my camera with sound at the moment to post a vid, and I don't think my old one can record sound, but I'll see. I need to avoid the son-in-law walk of shame with a dead car.
Any thoughts on how to test the injectors, or things to check out? Thanks!
