AzMahoony Hench, but no longer shredded or tanned. Member 3,343 Member For: 17y 8m 17d Gender: Male Location: Canning Vale, W.A Posted 26/06/08 01:32 PM Share Posted 26/06/08 01:32 PM Basically I've fitted it all up correctly..Injector rail line goes to the Pump, the regulator goes to the 3rd fitting on the Surge tank, the 2nd fitting goes to the bottom fuel line (attached the the fuel filter) and the top one on the fuel tank return line. I then filled her up about half a tank wroth of 98.Okay so She's all fitted nicely, anyways I've turned it on, and initially it runs like a dog, but it comes good (I'm thinking just air in the system) give her a few rev's and then hop in and drive around the block making sure Everything is okay.I've got back to my garage, and it starts running rough again, missing etc. try to give it some revs but its really missing, I can get up to about 2 grand really slowly then back down but It's really not running right.So I've turned it off, gave it a couple of mins, clicks over and starts but it then starts running Terribly and stalls, I then gave it about 20mins. I've come back and started her up, okay it stalls again. so I try once more and give it a little rev once I started it and it runs fine.I've let it run for about 5 mins at idle and everything seems normal (yep I can hear the FANTASTIC pump working its noisy magic haha) okay so I've reversed her out and taken it back up the street and it starts being a dog again and it stalls..Luckily someone saw me and gave me a push back to my place (great neighborhood!) and yeah That's where I'm up to with my car at the moment.And I was thinking I'd be able to drive it to Simon's.. lol Any Idea's guys? I was thinking too much Air in the system but surely it cant be this bad? OR a defect fuel pump, I'm not sure.Aaron Link to comment Share on other sites More sharing options...

Yeah that's got to be it for sure. sh*t injectors. Seems like you are not getting enough fuel under load. Put the lines back to stock and see if the intank pump is up to the task and is not causing the issue and go from there. Link to comment Share on other sites More sharing options...

I'll be taking pictures of underneath once I get home today see if anyone else can shed some light on this.It's starting to look like a defect pump although I hope it's just something minor.

Double check your earth and +ve feed to the pump to ensure your not getting excess voltage drop once the pump is under load. Link to comment Share on other sites More sharing options...

I've been searching for threads on people who have fitted this themselves but it doesn't look like many are as 'DIY' as myself with this setup :(I've currently just tapped the power directly from the fuel relay 'pink wire' it DOES work as I can hear it but, at times the sound disappears, So this could mean it's either a defect pump or there's not enough power there.With the wiring I've just attached the earth to the chassis of the car (near the ECU under one of the random bolts there) Link to comment Share on other sites More sharing options...

Use your current power supply to switcth the relay on and off. Its sounds like your running out of juice when you putting both pumps under load and thus no fuel. I wouldnt be suprised if your stock fuel pump relay is overheating and causeing the drama's.
