They go down to were it was smashed an then run under the the radiator support an then leads back up in the direction of the ecm

Yes when I had it hooked up earlier to the old scanner in the view chart mode when I was cranking numbers were coming up next ti the massairflow I noticed this when I told u about it showing the injectors opening up an I'm sending u a Pic of my fuse box lay out only thing that says voltage check is right about an next to the massbair flow sensor sorry to sound Un educated on this but electrical isn't my strongest suit but I'm checking that fuse now if there are any other fuses I should be looking at let me know but I wentvup an down the whole box an I found nothing dead besides the ignition coils which is cause the car wasn't being syatyed at the time because it cranks an cranks an just barely syatys an dies

You can test with key on, engine off, to see if the MAF is getting voltage with connector off the MAF
and then with test meter black probe to black pin and red probe to the connector pin of pink wire

I checked the voltage fuse it s hot both sides

Getting multimeter now

Pink wire is dead an so is maf fuse

OK so that is where the problem is and not your old PCM, maybe send it back when you get the engine running ?

Now you need to trace all 5 MAF wires down to the screwed up area and try to see where they could be shorted or broken

You could as I mentioned see by testing what is missing, not getting voltage, ground etc,
now know what color wire that is and then follow wires down and find that color wire and find the break, etc and fix
Then do a start test if starting then

Best case if you know how to solder (or someone who does

Go here, contact them and buy a new MAF connector, ask for one that has pigtails meaning the connector will have those 5 wires about 6 inches long

Go here : as they sell GM wiring connectors with and without pigtails
Or if you know how to crimp pins is buy the pins from them and crimp to wires on wiring loom

Then need some heat shrink tubing and some solder type wire couplers and cut the old wires near the MAF
Install the shrink tube to each wires from wire loom, do the solder splicing and then slide shrink tube over the splice couplers and heat tubing to waterproof each splice

Pink wire is dead when I checked with the test light an maf fuse is dead also an I have the ignition on I just swapped it out gonna check now the Grey wire showed power and again I apologize if I miss things ur saying I don't mean to

 

[Team ZR-1]

Pink wire is dead an so is maf fuse

Was that test with ign key ON but engine off, must do that for voltage to be hot

Well if you replace the fuse does it blow again and if not do you know have voltage at wiring connector of pink wire pin ?

That's WHT I tried doing when this first happened but I can't seem to find the issue or any wires that look damaged at all OK

GM is not common to use a gray or tan wire for voltage, normally use red or like pink

TAN and gray I think is IAT ?

 

[brandonkk51791]

With a new fuse still dead an ignition is on engine oa

OK pink wire isbhor again checking ground now that was the wire that was dead from the beginning checking the a now

Well have to follow exactly where the MAF wires go and closely look, damage to wires may be hidden but if finding the pink wire further back in wire loom could cut that pink wire and then splice a wire long enough to splice to MAF connector
But maybe more than 1 MAF wire got wacked ?

Being if MAF fuse is blown, that wire got cut and shorted to ground ?
Did you replace that fuse and then see at wiring connector if still no voltage to pink wire pin of connector ?

OK an the ground is live now to so the black wire is grounded an pink wire is showing voltage why is still not staying then

 

[brandonkk51791]

Just tried starting still not starting an then the po102 code came back low circuit like I'm so confused the connector is good an being powered why would I still keep getting low circuit issues then

OK pink wire isbhor again checking ground now that was the wire that was dead from the beginning checking the a now

If still no voltage at MAF connector, than a wire is cut in two

OK an the ground is live now to so the black wire is grounded an pink wire is showing voltage why is still not staying then

What is not staying on ?

 

[Team ZR-1]

Just tried starting still not starting an then the po102 code came back low circuit like I'm so confused the connector is good an being powered why would I still keep getting low circuit issues then

Low I think means PCM not getting output from the MAF on yellow wire

 

[brandonkk51791]

If still no voltage at MAF connector, than a wireI is cut in two


What is not staying on ?

No there is voltage now the pink wore is good the ground is good everything is hot and working but it still won't start an the electric start works also which I know if their codes it won't work that's why again I fell it's nit getting spark

 

[brandonkk51791]

Low I think means PCM not getting output from the MAF on yellow wire

So then maf sensor possible bad? It is from auto zone an they aren't known for their parts quality

Again, you need to trace to see if the output frequencies of MAF is getting to the PCM on the yellow wire
You need to trace that yellow wire from MAF and look for a wire problem to PCM

If coils were bad, it would be tripping codes for that and not MAF ones

What are the name of the MAF PIDs does you scanner support for this car ?

How would a trace a signal wire frequency that is something I've never done before? Cause the yellow wire isn't a power or ground so what would I need to do that?
