Pig Posted July 15, 2007 Author Share Posted July 15, 2007 Just checked hoses and all seem fine. I am wondering if it could be that 1 of the fuel pumps has packed up? They "should" both be new walbro's. Is there a way to check if they are both working? Quote Link to comment Share on other sites More sharing options...
Steve Posted July 15, 2007 Share Posted July 15, 2007 Take them out and test them. Were new power feeds fitted to the pumps? Just thinking of a melted power plug has stopped one of the pumps working Quote Link to comment Share on other sites More sharing options...
Pig Posted July 15, 2007 Author Share Posted July 15, 2007 Take them out and test them. Were new power feeds fitted to the pumps? No idea, will go and take them out now. How do i test them? Quote Link to comment Share on other sites More sharing options...
Pig Posted July 15, 2007 Author Share Posted July 15, 2007 Do i need to disconnect all the fuel lines to get the pumps out? What do i do about fuel going everywhere? Quote Link to comment Share on other sites More sharing options...
Steve Posted July 15, 2007 Share Posted July 15, 2007 I usually run the engine, then pull the plug to pumps to stop them, the engine will cut out, this should then reduce the pressure in the lines so you shouldnt get much fuel coming out. But just have a cloth to handy for when you do take the pipes off. Quote Link to comment Share on other sites More sharing options...
Branners Posted July 15, 2007 Share Posted July 15, 2007 has the car been to any other tuner recently for anything at all? If so could they have knocked something while working on the car? JB Quote Link to comment Share on other sites More sharing options...
Clarkey Posted July 15, 2007 Share Posted July 15, 2007 If it was running fine before but not now .. has your fuel pressure changed ? Is it possible that the hose from the pump & tank has perished or split and pump is sucking fuel up - leaking from the hose back into the tank ?

Steve Posted July 15, 2007 Share Posted July 15, 2007 I assume if you have 2 pumps, they would be fused seperately, are he fuses ok? Quote Link to comment Share on other sites More sharing options...
Jake Posted July 15, 2007 Share Posted July 15, 2007 Why have you got two pumps anyway? It's not necessary for a street sized turbo. Quote Link to comment Share on other sites More sharing options...
Steve Posted July 15, 2007 Share Posted July 15, 2007 Why have you got two pumps anyway? It's not necessary for a street sized turbo. Its the PHR kit i think which has 2 pumps. I could be wrong. Quote Link to comment Share on other sites More sharing options...
Pig Posted July 15, 2007 Author Share Posted July 15, 2007 Dam, just wrote a big reply and lost it. Branners: car only just came back from a full check over of the work. No work done on the vehicle though. Clarkey: not sure what pressure was before. What should it be with 2 pumps? Smarty: Pumps wired into the one plug at the top so only one fuse Bare wire showing too. Have pulled pumps half out, do i need to take the all the way out to check them? Jake: If i only need one then is the unlikely to be the cause??? Went for 2 cause i built the car ready for a bigger turbo. Edit: yep, phr stage 3 (2pumps) Quote Link to comment Share on other sites More sharing options...
Branners Posted July 15, 2007 Share Posted July 15, 2007 Branners: car only just came back from a full check over of the work. No work done on the vehicle though. how soon is 'just came back'? In these circumstances I tend to look at what was the last thing that happened to a car. JB Quote Link to comment Share on other sites More sharing options...
Pig Posted July 15, 2007 Author Share Posted July 15, 2007 Straight after!!! It went in for a check over of all the work (i thought you would have known this?) They didnt actually "do" any work on the vehicle. Am a bit stumped though. Going to put it all back together, try it. If its still fooked just give up on the idea of taking it to JAE.\s Quote Link to comment Share on other sites More sharing options...
foodfreak Posted July 15, 2007 Share Posted July 15, 2007 What are your af/r's up to 5k? as Jake said, dropping a pump wouldn't really affect your fuel pressure...... one can cope easily at your level, and it wouldn't happen only at 5k if they're o.k then it could be a duff vac hose conection loosing pressure to the fpr at those revs, OR it could be a glitch in your map....can you check the map? be very carefull Quote Link to comment Share on other sites More sharing options...
Clarkey Posted July 15, 2007 Share Posted July 15, 2007 Clarkey: not sure what pressure was before. What should it be with 2 pumps? If you have the stock FPR, the pressure should be 36 or 40psi. Fuel pressure to the fuel rail is controlled by the FPR - regardless of how many pumps you have. You'd need a fuel pressue gauge to check the pressure. I'm not saying that a leaky fuel hose causing a drop in fuel pressure - would be the definate cause of those nasty AFRs. But "I think" it maybe a possible cause. P.S - That bare wire you mentioned doesn't sound great!! Quote Link to comment Share on other sites More sharing options...
Pig Posted July 15, 2007 Author Share Posted July 15, 2007 Got an aeromotive FPR - Pressure is 30psi. Have found a pipe that isnt doing much about to post pics up to find out if it should be doing something Quote Link to comment Share on other sites More sharing options...

If its still fooked just give up on the idea of taking it to JAE.\s I knew of the work but didnt want to discuss the details unless you were happy to. Knowing the tuning company that did the work I would be surprised if they knocked something but it was a very thorough list of checks and theres a chance something got nudged. If they were in the footwell looking at the wiring then its also possible that something came loose. These cars get spaghetti in the footwells after a lot of work and its easy for something to play up and give the strangest results. If it was me I would get it taken back to the tuning company to check it over free of charge. If it was running okay before it went in and now it isnt then it points towards something they did during their checks. JB Quote Link to comment Share on other sites More sharing options...
Clarkey Posted July 15, 2007 Share Posted July 15, 2007 What are your af/r's up to 5k? I think he meant off-scale lean! > 16's ! Quote Link to comment Share on other sites More sharing options...
Clarkey Posted July 15, 2007 Share Posted July 15, 2007 Got an aeromotive FPR - Pressure is 30psi. Does that seem low ? I suppose depends on your injectors and if it was mapped at 30psi ? I'm not sure. But I would be asking that question - just to rule it out. Quote Link to comment Share on other sites More sharing options...

Thanks for trying to be subtle, im not in a great mood about this car at the moment. Off to check a couple more bits (ECU, Fue box etc etc) The only reason im attempting to do this myself is that i want the car back for JAE and this is the only way.
