Getting no spark and no fuel to my 512TR. Trying to figure out.

Hi everyone,

Hoping to maybe narrow down some issues.

Today I was going to take my 512TR to vacation with me and it won't start. It cranks over, starter works, all fuses are good.

I took out the spark plug and grounded it with it plugged on the spark plug. No spark. I didn't see any fuel on the spark plug either. When cranking the car over, I don't smell any raw fuel. I would think I would when cranking the car over and no spark.

I know the fuel pumps work. I put power directly to them and I could hear the fuel pumps kick on. Full tank of gas.

Checked the connectors on the coil pack. Looked at connectors and reconnected.

So I think basically I am not getting fuel and spark at this point. I swapped around relays and that didn't do anything either.

Any leads?

 

Found out if the 512TR doesn't get spark there's no fuel deliver either. I wonder if it's a crank sensor. Not sure if the phase sensor has anything to do with not getting spark?

 

I wish I could help but I am unfamiliar with the 512tr. I'm sure its some sensor or ground that cam loose.

 

Wouldn’t everything be controlled at this point through the ECU?

Then this makes me wonder why it wouldn’t run on one bank.

Do you think there is a common ground for both ECUs?

Just a follow up, I found the problem, I had a screw come loose in my phase sensor box.

 

what you understand under this phase sensor box?

 

Not sure what you are asking?

 

???
when you not even sure how could I know then???

you have written:

and I asked you what you understand under this phase sensor box?

so what problem you have not understanding my question?

 

the english doesn't make sense. maybe there's a translation error?

 

I think you're right.
