Update,

I've been in Hawaii for 10 days and barely thought about my car!

Going to get an adjustable FPR and try and get the 2 pumps working at idle. I'll try and find and fix the slight coolant leak and do some more trouble shotting on the whinning sound this week. I should have a new wideband sensor waiting at work for me as well.

For those that mentioned.... I already have the return fitting drilled out as suggested.

 

Still using oe fpr!??! Well that's your problem right there...

 

i remember reading in the project white build about only 1 fuel pump being operational at idle. i cant recall the specifics of the feature but you should look into it. note it s was done on the stock ecu also.

 

Buschur runs a single pump up to around 10 psi, at which point a Hobbs style pressure switch triggers the second pump. I have the parts to go about running the pump that way, but I prefer to have them both on all the time. It's less parts to fail, and you don't have to worry about the cross-over point making the tune vary. It's mostly personal preference.

 

I like your jobs

awesome !!!

 

Attention Dew Drinkers:



Since there is a noted dew drinker population following this thread I had to let everyone know about the throwback Mountain Dew made with real sugar. It is friggin tasty. I put one down last night while swapping in a new wideband O2 sensor and degreasing the engine. I was having flashbacks to my childhood, sipping sweet nectar and watching Dew commericals with Moto-x bikes jumping through waterfalls. Nice!

Turns out my coolant leak was coming from the feedline to the turbo. And it was good sized. I had coolant everywhere. Mix that with the oil still everywhere from the dip stick blowing out and it was time to degrease.

Should have the adjustable FPR in place tomorrow when Fedex arrives.

 

lol^

 

Moutain DEW!

 

Nice dude! I wish I have the money to build................

 

I got the adjustable FPR on Saturday afternoon and pulled another late night installing it and fixing a few other things.

The car will now idle with both pumps running. But not perfectly, and the fuel pressure is still higher than it needs to be. It's running at 55 psi at idle, it should be 34 psi. So I've still got an issue. I'm not sure what the deal is, the return fitting is drilled out and the FPR is set bottomed out. With a single pump it runs 20 psi, but both jacks it up to 55 psi. The crappy thing is that all the barbed fitting with high pressure hose on the Full-Blown Assembly make taking it apart and removal nearly impossible. The hose literally bond themselves to the brass fittings - I tried removing one casually and it was a no-go. To take the assembly out of the tank to look at things (the return fitting likely) is going to be a large swearing filled grunt fest. Worst case the hoses are cut off, and reinstalled with 1/2 less length, or they are replaced. Grrrrrrrr.

The coolant leak was indeed the turbo supply line. The joint between the hose and the banjo fitting. The factory spring clamp wouldn't squeeze tight enough. So I removed it, spilled coolant all over, and put a proper hose clamp on it.

Here's the MAP FPR kit, pretty good looking and includes everything you need - almost. I had to grab a return and vacuum hose, both were sitting in my garage.



Here it is installed. Anyone know why the manifold pressure signal line for the FPR goes to a solenoid? what would happen if you ran it straight from the intake manifold and eliminated the solenoid?



Here's a comparison of the wideband sensors. One with road rash, one without. Yes this could have been the reason for all these stupid issues I've been having. But it did work for a month in the road rash state - so who knows. Still need to go out and make some pulls with the new sensor.

 

Mines is eliminated on my car. I dont ever remember a cel from it either so you should be good. I also had it un-hooked when I ran a aeromotive FPR and it was fine too.

 

Im going to go w/ most of your probs were from a bad sensor. But hopefully you get all the bugs figured out soon so you can enjoy the car.

 

You can eliminate that solenoid and accomodate not having it through ECUFlash. Check in the Forum, and do a search for fp solenoid, you should be able to find it. I would find it now, but I am busting my **** at work corrently to generate Enginering Change Requests for our new truck we are building..

 

that is all egr stuff. you can disable it through periphery bits. I am running no egr/fpr solenoid and an not throwing any cels

 

I hate all ECO's, ECR's, ECN's etc. Paperwork FTL
