ihatejoefitz Posted January 15, 2008 Share Posted January 15, 2008 Car is a 72, engine is an 83 L28et. Installed per Moby's guide with 4-wire Hei. MSnS_E v.021s with relay board, tuning with megatune 2.25. I'm getting rpm, response from all sensors including TPS. However, I'm not getting a spark. I'm ggetting 5 volts across W and G, but nothing across B and C on the HEI module, is this normal? These are the settings I'm using, I think moby's .msq?

Matt Cramer Posted January 15, 2008 Share Posted January 15, 2008 Could you post your complete MSQ file? If you haven't started tuning, I'd recommend updating to the latest MSnS-E firmware, 029y4. It's got a lot of extra development put into it. Quote Link to comment Share on other sites More sharing options...
naviathan Posted January 15, 2008 Share Posted January 15, 2008 It would help if you posted some spark related settings. Everything you have up is fuel. Quote Link to comment Share on other sites More sharing options...

mobythevan Posted January 15, 2008 Share Posted January 15, 2008 You also need 12 volts connected to the positive side of the coil. This 12 volts comes on when the key is turned to on or cranking to power the coil. The schematic in the sticky does not show this, but the written section about coil wiring mentions it.

You're the man, that's what I needed I guess. I've got spark, but still not starting. I pulled a spark plug and it was completely dry. I put the multimeter on one of the fuel injector connectors and it showed about 1 volt during cranking. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted January 15, 2008 Share Posted January 15, 2008 Are the injectors high impedance type? How do you have them wired exactly? You should measure 12 volts on an injector connector when your not cranking, just turned on. Its a side note, but are you sure you have fuel pressure in the fuel rail?

ihatejoefitz Posted January 15, 2008 Author Share Posted January 15, 2008 Stock turbo injectors. I don't have a gauge, but there is pressure at the rail because I fixed a leak like 30 minutes ago, haha. Injectors wired like this. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted January 15, 2008 Share Posted January 15, 2008 I always like to listen to each injector with my cheap stethoscope to make sure they are clicking/working. Also, if you haven't done so yet make sure your timing is correct with a light ( I know it won't matter if your not getting gas, but you'll need to eventually). I'm not sure what else.

mario_82_ZXT Posted January 16, 2008 Share Posted January 16, 2008 Something easily overlooked is the TPS. If you wire it backwards the MS box goes into "flood clear" mode and doesn't squirt fuel. Mario Quote Link to comment Share on other sites More sharing options...

I checked for power with the key on and I get 12v before and after the resistor pack. Of course I checked the fuses... any other ideas?
