So, I was going to try working on jetting of the carbs today. But, unlike the past several weekends, when I went to start the engine cold, it didn't fire. No attempt at trying to fire... I went inside to retrieve the Crane HI6 documentation and see what I could find out. There is a single red led. When I turn the ignition on, it lights up solid. Using the troubleshooting part of the manual, I determine that no fault codes are triggering. I check for spark using my timing light. I get none. The HI6 manual says to crank the engine over and check to see that the led blinks. It just dims a bit when attempting to start but doesn't blink. I check power (red wire) and ground (black wire) to the optical pickup. I confirm power and ground. So... I am thinking the problem is the optical pickup. I read where if the white wire it put to ground, it will trigger the coil. I switch my timing light to the high tension lead from the coil to the center of the distributor cap. I disconnect the optical pickup at it's harness connection - wires (red, black, white) go from this connection to the HI6 control box. I pull the trigger on my timing light and ground the white wire. The timing light flashes, and the led on the HI6 control box goes out. I remove the slotted disk from the distributor shaft. I reconnect the optical pickup at its harness. I hold the disk in one hand and the pickup in the other and simulate the disc rotating within the pickup beam. The light on the HI6 control box stays solid - it doesn't blink like the documentation says it should when cranking. So, the pickup just "went bad", right? Am I supposed to actually see a light beam when the pickup is powered up? Because I don't.
I have a 1977 280z with a L28ET swap. I'm running MS1 V3 with a Relay Board I bought the car running but for some reason after I uploaded a new firmware it stopped. I realized I didn't unplug the coil which probably fried it. At that point I decided that I would redo the horrible and complicated wiring that the previous owner did in the car. I bought a MS Relay Board and the wiring kit as well as I switched out the NA dizzy to a 1983 Turbo Dizzy. I wired everything up and redid everything and the car is cranking but not getting spark. So I did some test to see why it doesnt work and where is the problem coming from. 1. I checked if im getting spark at the distributor...Im not 2.I checked if Im getting spark at the coil... Im not 3. I checked if I'm getting 12v+ to the + coil and I was 4. I replaced the coil with a 12v light bulb to see if while cranking it would light up... it didnt 5. I checked if the relay board is getting 12v+ switched while cranking...and it wasnt so i temporary jumped the 12v+ from the battery (does this mean that my ignition is bad?) I figured the problem must be within the Megasuirt itself. So my questions are: 1.Is there any way to check if the pin 36/s5 output actually works? 2. Is there any way to check if the coil ignition chip in MS is dead? 3. Is it possible that MS is not sending signal to pin 36 because i wired my Turbo dizzy wrong...any way to check that? Below I attached a picture of a diagram of how I connected the coil. PLEASE help me I need this car running since it's going to be my daily and I'm tires of borrowing my friends car. THANKS IN ADVANCE
Help....I have a 1978 280z that I have put a 1981 280zx turbo engine in, I have the 81 wire harness,ECU, Mass air flow and such. Problem is I cant get spark to coil or spark plugs. When I turn engine over and have coil wire grounded to body it will spark 1 time and that's is it. have new coil , another used igniter and the CAS that came with engine, Used wire instructions from hybrid,,,bunblebee z I think , have power to fuel pump injectors just no spark, have green light on at ecu. I am at a point to put 78 wire harness back in and just run it as a add on turbo engine or get a 82 distributor and shaft and swap. any suggestions would be appreciated
Hey guys, I am in Raleigh, NC and I have been working on a 260z RB25det swap for a while now and I am having troubles keeping it running. I did the swap last winter and I had it running this spring and summer. I took it to get it painted and then I left it sit for about 4 months. I finally got the time to install my autometer gauges the other week and I cranked it up to make sure everything was working. It struggled a bit to start and to keep running at first and I had assumed it was from sitting for 4 months. Now a week later I have tried to start it to take it out and set the speedo and it wont start. Nothing has been changed on the motor or electrical to the motor and it appears to not be getting spark. I hooked to tach up using the pull up Resister on pin 49 as I had seen many post as a working method to get the tach signal without blowing the ecu. I have checked that the cas is working by rotoating it and the injectors click. I have changed the old gas out for new and bleed the lines. The coil packs have power to them but I do not know how to check and see if it is getting spark signal. If any one has any advice I would greatly appreciate it. Also I have not had a chance to get in with any of the Z clubs around here but I would love to talk to some one who lives in this area with an RB Z.
