Spyder 96 gst is not getting power to the ecu.

Ok so this has been going on for a bit on the DSMTuners page on facebook but i'm needing all the help i can get since it's my dd and i need to stop bumming rides.

My friend has my car in his shop and i'm sending the updates to him so any suggestions is appreciated. He has checked grounds to and from ecu and he says they are all working correctly. Should i plug in my DSMLink and turn the key to on just to see if it will connect to the ecu?

Ignition switch is good MFI relay is good. I'm getting power to crank and cam sensors. Still no fuel or spark

I have 2 ecus and both worked perfectly before the motor was removed and I rebuilt it, one got sent to ECMTuning to be EPROM socketed.

I just can't figure out what happened between pullin it and puttin it back in. I traced all the powers and grounds to the ecu and they all seem to be working properly but I'm still not getting a check engine light. The ignition switch is sending power to the crank and cam sensors but they act like they aren't getting any signal. Now I have no fire and no injector pulse...

We have the motor freshly built. MFI/MPI is good, ignition switch is good, wires to the ecu is good, ecu is good, cam and crank sensors receiving power but seeming like they aren't receiving signals.

Oh and no check engine light at all

My friend is totally stumped and so am i. I am at the point of giving up but i don't want to

This may have been looked over by you but I have to say it fuses checked under the hood? and also there is a power wire that goes from the positive terminal to the fuse box make sure it is tight.

also check for cut wires

yes those were checked. we are leaning towards CEL light has gone out and that its the power transistor or the crank sensor that is bad. so those are the 2 things being changed asap

Double check (with meter) Room Lamp fuse in engine fusebox - it supplies backup memory power to ECU which I think must be there.

 

[spydergstftw]

will do it tomorrow

Fuse is good, have a known working crank sensor and PTU coming in soon so we will see what happens after those come in

Did you ever find what was the problem?
