Thread: Terminator X no spark or injector. Datalog HELP.

    Default Terminator X no spark or injector. Datalog HELP.

    Hello. Looking for some help looking over the datalogs (attached) to try to determine what my issue is. I'm getting no spark or injector pulse. Setup is LS1 (2002 Firebird ran when pulled) 24x, stock bottom end, heads & intake. Cam is a BTR Stage 2 turbo with their valve spring kit, 850cc SEP injectors, coil packs are mounted remotely, Twin 68/70 turbos. T56 transmission. I have spoken with Holley for several days and they're currently sending me a new wiring harness thinking that's the issue. They also had me send the ECU in for a complete check up and everything checked out to be good. While at Holley they completed a full firmware update. Here's a run down of what I've done or looked at. The ECU shows Crank & Cam signals while cranking (datalog). I replaced the crank sensor with a factory ACDelco to confirm that it wasn't not bad. The TPS has been calibrated and shows to be working as it should. Fuel pump primes for five seconds as it should. Fuel pressure is set at 60 psi and is confirmed with handheld and mechanical gauge. I get roughly 9V at coil & injectors while cranking, which I've been told should be enough to fire both. Handheld shows 110-120 RPM while cranking. Battery voltage stays @ or above 11.5 while cranking. At no point in time do I get any red lights on the ECU while cranking. I have all the +12V source wires ran directly to the battery or to remote battery terminal. The red/white wire is currently setup on a manual switch which is getting power from the remote battery terminal to confirm +12V while cranking. All power leads are ran off their own terminal to avoid any electrical interference. Coil grounds are attached to the back of each cylinder head. I have two engine grounds. The harness ground is grounded to the chassis. I've done a complete check of the wiring harness to confirm all wires are where they need to be and I've completed an Ohms check on all wires within the harness to confirm no wires are broke.
