Uberoo Posted March 20, 2007 Share Posted March 20, 2007 on an 89 MPFI fuel pump there are two wires that go into the pump.One at the top and one at the bottom.On my pump one wire is red and one is black so I thought red is hot and black goes to the ground.After I wired in my toggle to the wire that the red wire connects to( yellow with strip I think)...when I turn the pump on I can hear it do something but I have yet to recieve any fuel at the fuel supply line.I am wondering if possibly I have it in backwards?so I just need to know what wire off the pump is + and which one is -.Thanks...

Uberoo Posted March 20, 2007 Author Share Posted March 20, 2007 When I got the pump it had a different connector than what was on the car so I had to splice in the connector from the original fuel pump.When I did that I wired them in backwards.I found that out after I unbolted the fuel line going away from the pump and turned the pump on and felt SUCTION(on the line going away from the pump which would explain why I didn't have any fuel at the motor... now I just need to pick up a compression furule for my oil pressure gauge and she should RUN!!!

idosubaru Posted March 20, 2007 Share Posted March 20, 2007 i don't know from memory, but i have worked on that wiring before as well. you could pull the hose from the pump. if nothing comes out, switch the wires and try again. if it comes out then, you're golden. be advised, this is very dangerous running wire like that, it should be run on a protected line at least. make good, clean, tight connections.

Uberoo Posted March 20, 2007 Author Share Posted March 20, 2007 I soldered the wires together+ shrink tubing.Then I found out that my battery is toast so I got a battery from a friend that was 2 years newer may of 03 rather and august of 01...now I am charging that battery...

Uberoo Posted March 20, 2007 Author Share Posted March 20, 2007 F#$%^ the fuel pump is bad.It pumps air but it will no create enough suction to pull gas from the tank.GRRRR.That and the junkyard doesnt have one.son of a..... Link to comment Share on other sites More sharing options...
Uberoo Posted March 20, 2007 Author Share Posted March 20, 2007 What is an alternate pump that could be used off something more common?Just needs to supply FI pressure and enough fuel to feed EJ22.Would be great if the lines where the same size.

Uberoo Posted March 20, 2007 Author Share Posted March 20, 2007 could a pump of an 89 ford crown victoria with the 302 FI motor work?I found one for 25 bucks(after I trade my pump in its free plus I get 20 bucks back) Link to comment Share on other sites More sharing options...

On the inlet side of your pump there is a plastic screen, you can pop it out with a small screwdriver or an awl, see if it is plugged......Roger Link to comment Share on other sites More sharing options...
Uberoo Posted March 21, 2007 Author Share Posted March 21, 2007 how can I get fuel from the tank to the pump because it is worn enough that it is no longer self priming i will try the inlet screen trick tomarrow Link to comment Share on other sites More sharing options...
Uberoo Posted March 21, 2007 Author Share Posted March 21, 2007 I picked up a inline fuel pump off an 86 ford f150.I was informed that it was basicaly a direct bolt in with few mods.The fuel pump I got is huge compared to the old one.How is this supposed to be an easy bolt in mod?Zip tie the pump to the old mounting braket?Or did I get the wrong one?HELP!!!!

daeron Posted March 21, 2007 Share Posted March 21, 2007 I've never personally seen it, but it is my understanding that you can unbolt the ford pump from some of it's associated bracketry and then bolt it into the sleeve that held the original pump... don't be intimidated by any sort of large jacket that may be on the ford pump..something SHOULD be removable to make it more similarly sized to the subaru pump. And if all else fails, take the stock shelf off, drill some holes in it, buy some 6" hose clamps, and thread them through some holes to hold it onto the stock shelf.

Uberoo Posted March 22, 2007 Author Share Posted March 22, 2007 and then I lost the stock mounting plate somewhere... Link to comment Share on other sites More sharing options...
daeron Posted March 22, 2007 Share Posted March 22, 2007 Well my friend, you're only 19 right? necessity is the mother of invention; if this is the first time you've had to rig something like this, then take your time. Not all "ghetto-rig" jobs are as bad as they sound. Its not hard to find a way to secure it down, try going to a junkyard and finding something it will bolt to, then drill holes in the bracket you find to put the pump on, that match the mounting point so you can hang it where it belongs. patience, comrade. thats all it takes. its not hard to re-engineer this.

Uberoo Posted March 22, 2007 Author Share Posted March 22, 2007 Now Im really stumped.When I connected the ford fuel pump up it had some resideiual fuel in there.That shot out when I turned the pump on.Then I unbolted the inlet side fuel line and got my siphon pump on there untill fuel started coming out of the fuel line(a pretty healthy stream I might add)Then while fuel was flowing I put the hose back on the inlet.clamp it down and turn the pump on.all it does is dribble some drops out the other end.What the hell happened to the large volume of fuel that was in the lines?Why wont it pump?!!!!

daeron Posted March 22, 2007 Share Posted March 22, 2007 Trying to help you out, but its hard long distance with something like this. If I get condescending, and start telling you things you already know, please forgive A couple definitions for the sake of my post here.. Input line == fuel line from tank to pump prime == just make sure theres fuel in that hose vise-grip == preferrably a needle nose vise grip, or anything that can sufficiently clamp the line shut but is easily removable Also, careful for your eyes. gasoline in your eyes isnt fun, it gets all in your sinuses and everything.. if you DO get gas in your eyes/nose, flush your eyes with plain saline solution (find someone who has contact lenses) and if its in your nose, tilt your head back, inhale the same saline solution, and hoark it all out. repeat that flush in each nostril until your head feels somewhat clear. (I do this all the time just when I have a cold; its ESPECIALLY helpful when youve got something like gas in your face) One thing you could try is to prime your input line, clamp some vise grips on there as near to the fuel pump end as possible, then fit the line on, clamp it, and see if you get a good stream of fuel.. Isnt the pickup in the bottom of the tank? if so, then the line should be somewhat self priming.. make sure there is plenty of gas in the tank, and that youve got the cap off so air can fill the void left by fuel draining out.. Make sure you can get a good steady stream of fuel gravity feeding out of the line, then clamp it like I said, and attach it to the pump. I hope this helps. It sounds like you have already confirmed adequate fuel pump operation, so it shouldnt be too hard to get it primed and running. Link to comment Share on other sites More sharing options...
Uberoo Posted March 22, 2007 Author Share Posted March 22, 2007 after trying all that I took the fitting that was on the inlet side of the pump off.It appears to have a broken check valve blocking flow into the pump.Called the junkyard.evidently they do not test the pumps.This is twice that ive gotten a fuel pump from them that ran but would not pump.I guess I buy a new ford pump or something.I want this car to run but I dont need my savings drained out tring to get it to work with no job...Son of...

daeron Posted March 22, 2007 Share Posted March 22, 2007 hey, you want an idea that may seem a little shady to some?? Go to the junkyard you got the pump from, find another ford, and take that fitting and check valve off of another pump. Put it in your pocket, go home and fix the faulty pump they already sold you. Easy enough.. I know you've already run into stupid bumps in the road on this, but this one isn't too major to overcome. Good call taking the fitting off, check valves are a common failure point in ANY type of pump. Link to comment Share on other sites More sharing options...
Uberoo Posted March 23, 2007 Author Share Posted March 23, 2007 I got a me pump 2p74028 from napa $107 for the thing.boy they are going up... Then I found out a small canister thing that broke when I was puting FI grade lines under there was actually important.. I am using the Fuel supply hose for supply duh! I am using the vent hose as a return back to the tank because it was bigger. The little canister in question is right infront of the left rear tire on EA82.It has a hose coming in at the bottom and one at the top.The lower hose coming into it had fuel on the way back to the tank from the former "vent" system" Can I connect the top and bottom hoses together and complete the return system back to the tank or does the top hose go back to engine?It suddenly became a bit to dark under there to see what the hell I was doing...you help is apreciated.Car is a 1987 carbie wagon(as far as fuel system routing is concerned) Link to comment Share on other sites More sharing options...
Uberoo Posted March 23, 2007 Author Share Posted March 23, 2007 nevermind.I found the answer in an old post and about 3 pages off what I originally searched for... now where can I find a vented gas cap...for a EA82 wagon.... Link to comment Share on other sites More sharing options...
psylosyfer Posted March 26, 2007 Share Posted March 26, 2007 nevermind.I found the answer in an old post and about 3 pages off what I originally searched for... now where can I find a vented gas cap...for a EA82 wagon.... Might sound silly but I used a nissan cap with an 1/8" hole drilled right through the center of the 2 S's (where it said Nissan). On my wagon the whole time I drove it (about 7-8 years) never caused a problem. Guy I knew at a gas station donated the cap out of lost & found. had to drill the hole cause you could hear the gas tank crinkle when running before drilling. Kind of rinky dink but free is free!
