Yesterday, with some help from my 2 boys, I got my '76 2.0 short block on the engine run stand. I need help setting it up. It's late 2.0, complete, all stock, EFI. I'm looking for any info, any help at all. I've read few dozen threads about engine stands, but most of them deal with yokes, adapters and such. I need help with wiring and actually test running the engine. If local guys can stop by this long weekend and land me a hand, you'd really do me a solid and I'll return the favor. I'll serve beer of your choice. (IMG:style_emoticons/default/beerchug.gif)

Did you hook up your relay board? That is needed to tell the fuel pump when to turn on and the ECU power comes from the relay board.
If possible, give us a simple drawing of what you have now and we can get you in the right direction. Common problem when testing like this is too small of a ground wire to battery. Need something large! If you have a good set of jumper cables, use one of them from batt negative to trans case. Tom |

Tom,
The relay board is hooked up, however, I have fuel pump and coil hotwired. I have a simple dashboard w/ 3 switches: 1 - push button controls starter, 2 and 3 - toggle switches control coil and fuel pump respectively. FI harness all hooked up - all injectors, MPS, TPS, temp sensors, cold start valve etc. Alternator is connected to the relay board as well. Ignition harness is partially connected, but I don't really need it as I can control starter and coil w/o it. I'm attaching a basic diagram of the setup. It actually works and I can control starter, coil and fuel pump. I'm having difficulties with getting spark in cyl 1. Coil has good spark, but 1 cyl is very weak spark. Once I figured out that spark is the problem I stopped turning on the fuel pump and only use starting fluid in throttle body. Thank you, Mike Did you hook up your relay board?
