  1. Well make that 2 recent threads where it was a broken piston, 30psi of compression on cylinder #5
  2. Tested for ignition system issues this afternoon, swapped out ignitor, coil packs, and coil pack harness from a friend's car and the issue persisted, cylinder #5 is misfiring so next thing I'm going to do is pull the fuel rail and take a look at the injectors.
  3. Hey guys, I could really use some help with this one. Recently had a bucking/hesitation problem and replaced the MAF. The car runs better now than it did before and no longer stalls out but now it runs rough at all rpms and does not want to rev, as if its cutting in and out as I try to rev it. I’ve replaced the CAS, tidied up engine grounds, looked for vacuum leaks, and still can’t find the culprit. Any help would be greatly appreciated as I cannot figure this out for the life of me and I’m not finding any help online either.
  4. Hey everyone, I recently started having a problem with my Laurel where after a random amount of time driving, the car will start bucking and hesistating badly at all RPMs. If I put the clutch in or go into neutral while this is happening the idle hunts up and down between 1-2k and then stalls. When it stalls the car will not crank at all, but will start back up if I bump start it. By the time I got it home it fired right up with the key again until it eventually stalled. Any help would be greatly appreciated as I'm currently stumped.
  5. As a continuation of my last post, I’ve narrowed down the problem to the starter signal wire. When testing at the connector I’m only getting 2.5 volts. A test at the fuse shows 12, so the ignition switch itself is good. Obviously there is a problem somewhere in the wire but as it joins a large loom I’m having trouble finding where it comes into the cabin. Does anyone have a wiring diagram for the starting circuit or know where the signal wire can be traced back to?
  6. So I’m having a really strange issue with my Laurel. I was having to wiggle the negative battery cable occasionally to get the car to start. I replaced the negative cable and the car fired right up. After shutting it off and putting the battery bracket in I went to start it again and the relay clicks but nothing from the starter at all. Any help would be greatly appreciated. I have already sanded down the contact points for the cable but am not having any luck.
  7. I took the unit out for the front lights, they work perfectly when connected to a power supply and there is no voltage on the harness that plugs them into the car
  8. So I've had an issue with the cabin/dome lights in my C33 Laurel. They were replaced with LEDs before I bought the car, but they will not turn on. The fuse is good, but it looks like there isn't any power at the switch. Is there a common point of failure for the lights/wiring? I'd like to avoid tearing out all of the wiring unless I have to.
  9. I have a C33 Laurel with an RB20DET, and the car runs normally, but there's been an issue bugging me since I bought it. Whenever I go full throttle(or close to full throttle) and start making boost, there's a noticeable burning smell coming from the engine bay. There isn't any smoke, and the turbo spools up just fine. I've checked the oil level often, and over the 4 or so months that I've owned it, it hasn't dropped noticeably at all. Is this likely a blow-by issue? It does have a pod filter, straight pipe exhaust, and external wastegate. I would think that a bad turbo would consume a lot more oil.
  10. It is a C33, the C33 went from '89 to '93 in Japan. Those were the only screws that I could find in that area of the dashboard so what you were saying sounds right, I just didn't want to force it and break something since getting C33 parts in the US isn't exactly easy
  11. Are those the only ones you have to remove to take out the trim? I pulled those out but I was scared of breaking the trim if there were more that I couldn't find
  12. I recently ordered a speedometer cable for my 1990 Laurel because the speedometer stopped working. I'm ready to put the new one in but I can't figure out how to remove the trim to get to the gauge cluster. Any advice would be appreciated!
  13. Hey guys, I have a C33 Laurel with an RB20DET out of an R32 Skyline GTS-T, and I'm having a problem that has me stumped. 2 weeks ago my car randomly stopped cranking when i turned the key, I figured it was the starter so I've replaced it and still nothing. When I turn the key I hear the fuel pump, and a relay click from inside the dash. The dash still lights up, and the radio still turns on, but the starter doesn't turn at all. Any help would be much appreciated!
