October 22, 201115 yr comment_561948 ok so i got another fuel regulator as my original one was f@$k well i have 2 after market ones (AS THE STOCK ONE IS f@$kED at 30 ish psi it will idle on its own but wont rev 125 psi it can almost be driving but dies under slight load i have had best results from using a basic aftermarket adjustable one and have had less results from the rising rate one so annoyed help Edited October 25, 201114 yr by t18drifts Report
October 22, 201115 yr comment_561950 125 PSI? WTF!?! you sure its a fuel problem not a ecu signal, (TPS, injectors, o2 sensor, coil, leads etc etc?) Report
October 22, 201115 yr Author comment_561952 yeah it will idle nicle at around 30ish psi but wont rev at all and will only rev with excess pressure Report
October 22, 201115 yr comment_561955 That's not a fuel pressure problem. most EFI's don't need more than 35PSI. Time to check everything else!! What ECU are you using? Report
October 22, 201115 yr comment_561956 also what do you mean wont rev? foot down will it slowly pick up? NEED MORE INFO, please ring customer to confirm problem. Report
October 22, 201115 yr comment_561959 Yeah, ring Evan!!! Could be fuel filter, where are you measuring the pressure, at the rail, pump, before or after the filter?? Report
October 22, 201115 yr Author comment_561960 stander ecu guys with knock censor thingo only thing i have change from stock is the turbo (T25) and o2 censor (one from a sr20det) it will rev slightley at 35 40 psi but wont go any higher then 2500 if that even if you slighlty rev only time i can get it past that is with excesive fuel pressure Report
October 22, 201115 yr comment_561961 i also think it might have to do with fuel flow not pressure Report
October 22, 201115 yr Author comment_561962 also what do you mean wont rev? foot down will it slowly pick up? NEED MORE INFO, please ring customer to confirm problem. whats your number bro Report
October 22, 201115 yr comment_561963 So you've replaced the single wire O2 sensor(standard) with a 3 wire O2 sensor(SR20DET)? Report
October 22, 201115 yr Author comment_561964 one thing there is wicked pressure in the tank when i disconect the return line on the regulator to the tank i get fuel spitting back up with great pressure when everthing is of Report
October 22, 201115 yr Author comment_561965 So you've replaced the single wire O2 sensor(standard) with a 3 wire O2 sensor(SR20DET)? wait I'm not 100 percent sure its a sr one it was single wire and fit in the t25 dump Report
October 22, 201115 yr comment_561966 Have you got the fuel pump connected to the right line? sounds like you have the pump connected to the return line!! Report
October 22, 201114 yr comment_561983 sounds like fuel cut out to me.... ECU. Edited October 22, 201114 yr by GJM85 Report
