No start after engine rebuild

This is what I see

 

Yes they are tyranny codes the wire is broken I'm replacing when it comes in

 

I ordered a 11PC Fuel Injector Tester Noid Light Set IAC Circuit Diagnostic Update Kit it will be here in 3 days I'm not going to test ground to the ecm till then

 

Look through your data list for any PIDs related to fuel.

I'll take a look at mine later and see if I see any PIDs to look closer at.

 

interesting info

 

Scroll around in engine data and find the Crank sensor (CKP) and cam sensor (CMP) and fuck with it and see if you can come up with a graph showing all 3, then crank it and see if the ECM is seeing data from all 3

 

guess your master mechanic's garage hasn't a clue

 

Did you miss my reply to this?

If it starts with starting fluid it's your fuel delivery system.

 

This brings up a question?
Are the fuel and spark controlled by different sensors.
Spark is likely controlled by Crank sensor. (And you have spark)
Fuel might be controlled by cam sensor. As fuel and valve timing go together.
@Dm93 might know what sensors controls what?

I know you say you have changed sensors.

Sure would be nice to have a scope.

 

We should see codes for cam and/or crank sensor/timing problems but yea it would be nice to see what the signals look like.

I know it will run without the cam signals, it will not run without a crank signal.

 

You may want to look at these PIDs key on and while cranking.

 

Not a master just a shade tree, I bought an autel ran for codes fuel pump wasn't working I changed the cam sensors it worked still no start so I changed the crank sensor still no start so I bought a spark tester and so on hell by the time I'm done I'm gonna go get certified lol

 

By the time you are done, you’ll know more than most. Most of what I know was learned when I had to fix what I broke. Isn’t it funny how stuff breaks really fast, but takes forever to fix.

 

From the videos I have watched it all is pointing towards my injectors not being grounded to the ecm. Now I may have broken the ground when I pull the motor wire harness got hung on back of block ill test that when my test set comes in , in a few days

 

The PCM controls the ground on each injector individually, odds of all 6 wires being broken are pretty slim.
I would expect other codes and issues if a PCM ground was missing.

 

Is the fuel pump working now? Do you have fuel pressure at the rail?

 

Injectors receive a constant 12V. The ECM pulses the ground to fire the injectors. Unless you broke 3 or 6 wires, it should still start.

Is there any gas in it?

 

Yes I put 1/2 a tank in it pressure is good

 

take it back to the shop that did the rebuild. Let them figure it out

 

Ok got a noid light set from hf 21 bucks come home try cranking it no pluse?? But have power to injectors??
