Hi all ive been having a few problems with starting my project mk2 xr2 with the erst mfi engine and have been pulling my hair out for weeks. The area im stuck with is the metering head. I think basically its plumbed in wrong and ive made a silly error in where the various fuel pipes go, can anybody label the picture below, the main areas im stuck with is, from the fuel filter to metering head, and which connection is fuel out and back to tank, it would be muchly appreciated

project thread will be on soon............


Thanks

Jay

 

from the fuel filter it goes to an accumulater before going back to the pump i think you might be missing an accumulator as everyone doing a conversion misses this hope this helps what is your problem will check my car for more info tomorow

 

right basicly i have my fuel line coming from the tank connected to my fuel pump from the fuel pump the line goes to the large accumulator from there ive got it going to the fuel filter its from the fuel filter into the metering unit im stuck with just basicly need to know which connection on the metering unit does the main fuel line go into and were the exit line is and the route back to the tank , thanx

 

i will look tomorow but upto that point you are correct are you sure the metering unit works as there are alot of duds i had 5 only 1 worked

 

yeah im pritty sure the metering units ok was running in a car up untill a month or so ago , ive never had this car running as only just finished fitting the turbo engine into the fiesta and as the metering unit was bare of pipes im just not sure which connection on the unit goes were all the injector ones im fine with just the fuel line in's and out's and into and out of the regulator and back to tank ,

 

check the flap, and check to see if there is fuel getting to the metering unit,

 

When i turn it over it will start briefly but thats all, the flap on the metering head moves up and down quickly and i can hear like a high pitch casio beep coming from that area when it doesnt start. I think the problem may lie in the way the metering unit is plumbed in, with the lines in and out, there is high pressure fuel getting to metering unit also

 

right here we go from the fuel filter to the pipe next to the black box that bolts onto the metering unit the 4 on top and one to the side is to the injectors and cold start the next one is by the black box which is stuck to the metering unit is connect already correct on yours the next one across is a blank then the next one is to the bottom of the regulator then the end one on the regulator is a return hope this help let me know

 

thanks for getting bk to me im just gunna run around to garage to have another look bk soon

 

This is how mine is

 

have you blocked off the hole that the breather goes into near where the boost pipe goes onto
as

 

Ive put a bolt in there seems a good fit,

 

thats right seems like a dodgy metering unit have you tried pushing down the flap while trying to start it maybye it needs adjusting. can you hear the pump working if not bridge the relay and try starting it imediatly or it will flood it mine does anyway hope this helps

 

have both of the black conecters on the metering unit got wiring to them as mine done a similar thing and one of them was not fitted just remembered has it got a dump valve on it if so remove it and try it as single piston dump valves can cause a similar problem

 

Thanks for getting back to me Right..... posible good news, I had it running for about 10 secs reving and lightly dumping, after priming the fuel pump bout 10 times and it ran. The problem I think is that I do not have a non return valve on the pump found the connection and ordered the banjo and cap nut off ebay today so fingers crossed...................

 

hope it works that is what the fuel accumulator is ment to do aswell mind keep the fuel up ready to start hope you get it sorted anyway ive just started to get mine sorted fuel pump relay works as it should now lol just want mondeo 16 inch alloys keep looking and will find hopefully

 

What project have you got? hopeflly this will sort the prob, and a bonus is when it ran it sounded good, first time its ever been run.
