Possibly i will check. back when i first fired it i heard a knocking and then it went away i assumed it was just from all the low oil since when i started it a few mos. ago it hadn't been ran in 5 years.

I've got some core injectors that are known good you could try. Or you could switch injector 1 and 2 (or any other for that matter) and see if the misfire moves. I don't put much faith in a company that takes your pump and puts it back on the bench. Most all companies would just send you a new pump. If internals are good, which a misfire caused by mechanicals will typically cause low compression we're limited to a bad pump or injector. Connector tube would cause a hard start or fill the crankcase with fuel. What company is rebuilding the pump? Are they bosch certified?

Here is how you test you pump take off the #1 feed line take it with you to the hardware store and you cobble up a pressure gauge that can read up to 20,000 psi or at least the highest you can find and you install it on the number one port on the vp and see if its get pressure on the run cycle

How would that cause pump damage ??? If he is unsure the pump even works i guess he can just leave the line off and see if its geting pressure

That I know of there are only 6 test benches for these pumps in the US. Motive, jasper, mwfi, industrial, ofi & dfirc. If it didn't come from the above there's a slight chance they don't even own a bench capable of testing the pump. Sent from my SCH-I605 using Tapatalk 2 |

I got it from advanced metal and diesel parts out of utah. Any other test options? Maybe the valve stuck shut. Cant be timing so its valve or pump. I switched the 3 and 1 injector back when i got the new one.
