Can you try running it on an alternative fuel? Like have someone spray brake cleaner into the intake tube to keep it running. Then you can narrow down fuel versus spark problem. Also, try using a...

That sucks......another $100 down the drain. Live and learn I guess. Thanks for the quick reply Bill.
I had a PCM formatted by Speartech to fix a VATS issue. In doing so they changed the VIN, and now I have to license the PCM in order to tune it. Is there a way I can terminate the previous VIN...
Speartech solved it. It WAS a VATS issue, like I'd thought. Once the PCM was shipped back we installed it and the injector pulse was present. Engine would start, but needs to be tuned, as the tech...
No codes. And I too was shocked to see injector pulse width data when they are indeed "dead". I have contacted Speartech, and it sounds like this is a common issue with using the E38 ECM in a...
***Update***
Tested fuel injector pulse with a noid light. No injector pulse. Yes, there is power present at the injector. I tried changing the VATS patch status from "disabled" to "enabled",...
When I cut the harness I joined all grounds to two locations, just to make it simpler, one on each head. The plugs look like new, with only a hint of tan. Definitely not the black I would expect...
That's the same conclusion I was coming to. I've added to the MAF table to try and add more fuel, to no avail. The pulse width and duty cycle shows the injectors firing, but I've still yet to...
No progress to report. Haven't tried again since the post. The engine was turning over, and actually running during that log. You can see the cranking rpm is around 200, and its around 1000 when...
Its drive-by-wire. So the TPS is showing the position of the throttle blade during a cold start. The APP is the pedal sensor, and that behaves normally. Since there is no IAC, the throttle blade...
Yes, full exhaust. It is in open loop currently, I set the closed loop enable to maximum.
The fuel pump is 190LPH in-tank pump, and using a C5 filter with integral regulator. The pump is...
Any other suggestions or things I should check?
Speedo problem is because it an aftermarket sender on a manual trans. Do you think maybe the speedo being maxed like that is cutting fuel, like a governor or something? I believe I turned off all...
The silence has me thinking that I'm not overlooking something simple, which is good for my ego. But, I'm still no better off overall. I have yet to verify injector firing with a "noid" light, so I...
I've been trying to get this thing to run, but the best I can get is small rumble on occasion unless I add an alternative fuel (brake cleaner). I replaced the MAF, because during start attempts I...
Thanks for the reply. I am not ruling that option out, but I'm not giving up on it yet.
OK, I was told that pin 47 on the green connector can be used for this. Its the 1-2 shift solenoid normally, but that doesn't matter in my application. When activating that circuit with the VCM...
I was trying to find a pin location for a shift light activation circuit on a truck PCM (Green and Blue connectors). I see in the HPT software that there is a field for this, and that its a PCM...
