eke_zetec_RWD Posted August 28, 2008 Share Posted August 28, 2008 krimp the fuel return line and then try to start it, if there is a lot of fuel returning then the regulator may not be working Quote Link to comment Share on other sites More sharing options...
fishtailfred Posted August 29, 2008 Share Posted August 29, 2008 ^^^ what he said. a factory boost referenced bosch one > aftermarketthey have much better control, better seat materials/geometry etc. Quoted for truth. However, OEM ones often don't flow enough with a BIG pump. I have a china one and the only down side is it doesn't hold pressure without the pump... = slightly harder starting when hot theoretically. Yea pissing out fuel through the return.. Doesn't mean much unless you know the regulator is good. This may be a dumb question, but it DOES have a regulator doesn't it? If so, what type? If not OEM, where is the adjustment set to? If not, there is your problem Quote Link to comment Share on other sites More sharing options...
RT Posted August 30, 2008 Share Posted August 30, 2008 I doubt the injectors are faulty man, it was working mint for me when I gave it to ya. They don't tend to get dirty just sitting around if they've been in the fuel rail this whole time sealed up. Is the regulator the same one that I gave you or have you changed it? I would make sure the injectors are actually firing (clicking) as nismo has said cos it sounds like they aren't getting the signal which is a wiring fault Quote Link to comment Share on other sites More sharing options...
fishtailfred Posted August 30, 2008 Share Posted August 30, 2008 could it be bad positive feed to the injectors? (ecu supplies ground signal) or resistor box being used with high z injectors? Quote Link to comment Share on other sites More sharing options...

Ok just remembered, when I was first trying to fire it up and it wasn't firing, we pulled the return off and no fuel coming out, pulled the inlet off and fuel pissed out, so thought it must be the regulator. Pulled the regulator off and then put it back on and it had fuel then, possibly it's not letting enough through? I'm thinking that or wiring. I have no time at the moment to check anything as I'm always working out of town lately but as soon as I do then one of the suggestions made here will work.

Guest vvega Posted August 31, 2008 Share Posted August 31, 2008 regulator after the injectors aye ...... Quote Link to comment Share on other sites More sharing options...
Josh Posted August 31, 2008 Author Share Posted August 31, 2008 no? Quote Link to comment Share on other sites More sharing options...
Guest vvega Posted August 31, 2008 Share Posted August 31, 2008 line needs to go tank - pump - filter - fuel rail - regulator- return to tank the purpose of the regulator is to build pressure in the fuel rail cant do that if its before it Quote Link to comment Share on other sites More sharing options...
Josh Posted August 31, 2008 Author Share Posted August 31, 2008 Oh ffs!! I even asked a mechanic about this and he said it went through the regulator first so took his word for it. Damn I feel stupid as now, just have to swap the return and inlet lines around and technically should be sweet b the sounds of it..fuck Quote Link to comment Share on other sites More sharing options...

Ke36 Posted August 31, 2008 Share Posted August 31, 2008 mechanic was probly thinking it was still carby pinto for carby setup reg goes in supply line so carby isnt flooded with gas for injection, regulator goes in the return line to keep the pressure in the fuelrail at correct pressure Quote Link to comment Share on other sites More sharing options...

Josh Posted September 1, 2008 Author Share Posted September 1, 2008 He knew it was injected. He had messed a couple things up actually that I was getting done so I took it off them and went back to sorting it out myself, kinda scary when you trust people that are supposed to be ace at their job? I get a new injector seal tomorrow that I lost so if it starts I'll update my project thread ha Quote Link to comment Share on other sites More sharing options...
forced Posted September 1, 2008 Share Posted September 1, 2008 Mechanics are only good for brakes and clutches. Auto sparkies are trained on EFI. Well to be fair, there's good ones and bad ones like everything else. If you've got low pressure electric pump and carbie, the reg goes in line before the carbie, different from doing it EFI.

Josh Posted September 2, 2008 Author Share Posted September 2, 2008 Ok so heres the deal... Swapped the inlet and return lines around now the injectors are definatly spraying as they should be. Got a few backfires out of it but it didn't actually start. Did the timing on it by getting the number 1 piston at TDC and then turning the dizzy untill it pointed at the number 1 lead on the compression stroke. Still didn't help the starting factor, got a few bangs out the exhaust but still no actual firing. Anyone have anymore ideas/maybe it the computer?

lowlancer Posted September 2, 2008 Share Posted September 2, 2008 Try flicking the rotor in the dizzy round 180, you'd be surprised. I tried you way of lining it up but it didn't work as I'd actually gone past the sparking point. Give it a nudge anyway Quote Link to comment Share on other sites More sharing options...
Josh Posted September 2, 2008 Author Share Posted September 2, 2008 But wouldn't that mean it's not on the compression stroke? Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted September 2, 2008 Share Posted September 2, 2008 remove rocker cover, turn engine by hand untill the front two lobes are facing up. this is the compression stroke. timing marks should line up. remove spark plugs and clean. with injectors unpluged.... set static timing using the ignition limit in ecu and a timing light. set limit to zero and then adjust dizzi etc. turn ignition limit off. plug in injectors. try start engine with a mean battery. if no fire but has good spark check... for fauled plugs etc etc Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted September 2, 2008 Share Posted September 2, 2008 You on the right stroke? you can check this by taking rocker cover off and seeing at which time the valves are opening. You'll probably backfire out the inlet if its 180 out I found. Quote Link to comment Share on other sites More sharing options...
