Helping a friend with the install and start up of his 496 Stoker with Holley Terminator FI. This has been a several month long project that we have been working on. Yesterday was finally time to get it started. Which did not go well. The engine is fresh build that was on the dyno at the engine builders. So it was already tested and tuned using a dyno carb. Break in already done.
The system is the Holley Terminator FI system using an in tank pump with inline fuel filters and a Holley return style pressure regulator. The fuel is filtered before it gets to the fuel injection, from there it goes to the regulator, then back to tank.
We ran the fuel pump, flushing out the lines, and getting fuel to circulate in the system. We followed the Terminator start up instructions, set up a base tune, all the sensors were reading back, except A/F because the engine never ran. We could not get the engine to run. It would crank, try to fire but never quite get there. Tried moving the dizzy both ways, nothing. Finally put the dizzy back on the mark and dribbled some fuel down the FI unit, and it would start for a few seconds at a time but never fire off and run on it's own. So it looked like ignition is not the problem.
Holley wants 43 psi of fuel pressure. We ran the pump manually and set the pressure to 43psi.
Double checked the firing order, and made sure the the dizzy was pointed to #1 plug when #1 was on top dead center, 0° on the timing mark. Besides the engine would run when fuel was poured in.
Went in to the advanced tune section and turned up the fuel enrichment parameters as much as we could. Still no run.
Battery voltage had dropped to just at 12 volts. Could that voltage be too low to fire the injection?
Holley tech had already closed by this time. We were both completely frustrated and gave up.
Any one have any ideas we could try? We will have to call Holley tech next week and see what they recommend to do. Believe me, Mike and I have waited a long time to hear his beast come to life. Tomorrow would be a good day if we could get this figured out.
