I'm lost at this point...

Correct Drake, it will not fire till it sees 500 psi. I have had 1 with a bad lpop with the same issues. It sure sounds like a hpop leak or weak pump. I could crank mine on gold brake clean it would run fine till shut down. Try to restart and nothing. The lpop was so weak it wasn't pumping enough oil while cranking over.

That was going to be my next sugestion.. lpo pump... with the valve covers off, have someone crank the motor and watch the oil spouts on the injectors.... maybe just bypassing through them.

Is there a port I can put a guage on the test LPO? 16-20lbs about right?

 

[Magnum PD]

Subbed.

 

[lincolnlocker]

Oil filter head has a port on it.

I'll check LPO. And report back

Have you tried un plugging the icp sensor so I see's max value and try to start it?

 

[Rideracelivemx7]

cold LPO was around 40-50PSI IIRC and once warm it quickly fell to 16-20 like you mentioned.

Have you changed the HPOP? I don't remember

Negative, have not gone that far yet.

I haven't got to the shop this morning yet.....when the south receives an inch of snow they act like the world is going to end. 25 in a 55 on a well salted road

have you blocked off each head yet? That will answer so many questions. It WILL fire on 4 injectors if you can block off the side with the leak. If it will not fire either way then you know for a fact its LPOP or HPOP related. Takes a lot of guessing work out of it.

Forget anything electrical at this point. You can even ground out the IPR so you know for a FACT that it is closed up and building as much pressure as possible. Only leave it like this for seconds at a time though, no extended periods of time.

:whs:

 

[Motostroker]

Ok here is what I found.

LPO is 40psi
I blocked off the left head with a 6an plug in the hose and put a 4k psi gauge in the right head. Cranking the max I saw was 250psi.

I swapped the plug to the right head and gauge to the left. 250psi max.

I think HPOP said goodbye.

 

[Motostroker]

Btw I also tried blocking off wash head and cranking. Still 250psi. It simply cannot build psi out of the hpop

We have T500's available if you need a pump!

Shoot me a PM!

 

[lincolnlocker]

Havnt checked in a while but a t500 is a cheaper route then buying a reman pump I think...
