Due to some family stuff goign on my pump didn't go in for Zdayz. I'll toss my old printouts and use the new one and give some feedback.

On a side note, I need to chat with you about the Z34 oil system at some point. I know you looked at the reasons the pumps failed and would like to get some thoughts on my engine build.

I started having issues on startup. car dies right after start-up, very intermittent though, I can keep it alive with giving it some gas. It started happening more recently in conjunction with "no SES light, but limp mode".

do you think the bad pump is a culprit or something else?

Rusty · 02-14-2017, 10:46 AM

You need to install a fuel pressure gauge to know if it's a pump or something else. phunk has a nice little kit.

could be a small leak in a gas line

Let me know if your issue has been resolved, improved, or gotten worse! I would be happy to help you diagnose it if there is still a problem.

thanks for the follow up, the issue seems to have gone away on its own. it's been a month without issue. limp mode problem also fixed itself. I'm not quite sure if it was weather related, or maybe dusty air related since I'm daily driving this car into construction site

phunk · 02-14-2017, 11:52 AM

Id agree that a fuel pressure gauge is going to be the easiest way to diagnose a bad fuel pump if you are not familiar with fuel system work.

Otherwise, you could always pull the fuel pump module out the tank for an up-close inspection and test giving the pump 12v.
