hi there i have a 1998 tdi endura engine escort

currently it is not starting and have been told it is the start stop valve shut off as i got fuel going to pump and fuel out of return but none at injectors,

my trouble is i dnt know where the start stop solenoid is

anyone know

only had car 2 days and it died,

desperate to get it going again, fitted two new lower arms and it died on me


dont wanna touch until im definatly sure which one


dont know how to up pics so here is link

it looks like a lucas pump and if it is you have to cut open the pump to change it, are you sure it aint a immobilizer fault has they been any build up to this at all?

 

you are right it is a lucas pump, it was running fine for a couple of days with few slight misses here and there then one morning i came out and it was quite cold and its cranked a few times to start but i thought some of the glow plugs were gone so i replaced glow plugs and it fired so i thought that was it, then i drove to a friends 15 miles away and parked it up for 3 hours and come back out and nothing, so my friend a mechanic said to check immobiliser light to see if it was flashing when starting and it wasnt so he said its probably the start stop solenoid as i have fuel to the pump else he would reccommend the primer,


any ideas where i need to cut to get at the solenoid

 

best to take the pump off you can do it with a dremmel drill with a cuting disc on it but its very time consuming

 

well before taking pump apart i decided to get my mate whos a mechanic around, he had escorts for years so threw it past him, he checked everything over and said there is fuel going to the pump but not enough pressure to go to the injectors and the primer doesnt go stiff when primed so he diagnosed it to be the primer so i will get one asap and fit and see what happens

 

hi guys i changed primer pump and it went hard when primed unlike old one so result on that, opened injectors and cranked over till fuel came out, fired up left it running for an hour then drove it 20 miles , turned it off went back and wouldnt start , on the 20 mile drive it cruised along at 85 no problems , but on lev revs it was missing, so i wonder if air is getting in somewhere else, any ideas would be a good help

 

Sometimes the valve in the plastic fuel line from the primer to the pump can draw air, try sealing it up or bypass it.

 

got a feeling the fuel is returing back into the tank hence it wont start put a one way valve in so it wont run back, look on ebay for one, the slighest air lock will stop it from starting sometimes you have to drag them down the street to get them going, but one its started it should be bled. must have a air leek somewere

 

would i be right in saying they have non return valves as standard so mine could be faulty

 

Stick this in the supply line as close to the pump as possible

Ok will do thanks

 

sorry if its a stupid question but where in the suplly line before it goes to primer head or between primer and fuel pump

 

would be before primer so the filter stays full, you could put a simple clear fuel filter in too so you car see if the fuel is there or not

 

ok will do think i will have to modify piping as its all plastic at the minute

 

ok modified all piping and put one way valve in, diesel is goin to pump, just wondered if there was a relay that controlled the pump start stope solenoid cos now i cant get fuel to come through the injectors, wondered whether may be a faulty relay or whether it is the solenoid still, as well as the what i hope i cured now the air leak

 

Slacken the injectors and get someone to prime the pump while you're turning it over.

 

will try tomoz thanks andy

 

well i got fuel coming throght the return of the pump still but still no diesel through injectors so i am still thinking its that start stop solenoid, whether its faulty or if it is wired to a stat or something which tells it when to open i dnt know any ideas guys

 

hi guys there is 3 wires that go to the shut off solenoid on my pump something to do with pats?????, any ideas what these 3 do as as far as i was aware it would only need a single 12v feed, anyone know if this is bypassable cos its an antitamoer casing around my solenoid so i gotta take pump out just wondered if any tricks to test without taking pump off

 

hi guys just to update 3 hours with a dremel to cut solenoid casing off , 39 mini discs snapped later and im through, got solenoid out to find it not working, so ordered standard type solenoid with ignition switch live feed , gotta fit that and hope i get fuel out of the injectors , fingers crossed anyway

 

I've the same fault with my van.i change the prime pump too but the immobilizer was flashing so i think its the stop solenoid and was just wondering how did you get on with yours

 

ye after fitting new typesolenoid used a ignition fedd and the car ran like a dream, only to mot it a week later and it fail badly nevermind i won the battle in the end,

dnt like being beaten

 

I need to change the timing belt anyway so i'll pop off the pump to put the solenoid on it.Its alway a battle with a ford
