Hi all,

I have a 1989 xr3i cabriolet its been off road since 2008, when i got it car wouldnt start orturn over due ti imobilisers. Had auto elec removed them all and started work on it......new alternator,,, new dizzy, ht leads and plugs new timing belt,water pump, all filters fuel and air all new oil and filter all new brake discs pads and pistons.. i have had 3 different fuel pumps all new on cheap ones from £40 to the proper bosch one £150 all 3 did same its ok for 10mins then starts making a loud noise.. when i take car out it drives ok normal for a while but as soon as you put your foot down it starts to jump and splutter and cuts out it then wont start for bout 10mins and goes through the same routine any help or advice would be greatly appreciated

Thanks in advance

Andy

 

Has it got fresh fuel in it? And enough of it? The pumps usually go noisy when they are pumping air opposed to fuel!

If you took the fuel pump out the equation, it will be the Jetronic setup. Warm up regulator or Metering head will be the obvious culprits - they are probably gunked up and/or corroded to buggery internally depending how it was all left. The fact it runs for 10mins from cold I'd be looking at fuel pressure first and foremost. Then that will identify if its crashing out, in which case start at the WUR

 

Thanks for reply yes fuel tank was drained and there is plenty of new fuel in car the fuel pump is definatley pumping it out no problem. I will have a look at cleaning out the warm up regulator ss youve said and see if that makes any difference

Thanks

Andy.

 

Have any flexible fuel lines been checked / replaced?
Have any hard fuel lines been checked for partial blockages / corrosion?
Does it have a fuel pump relay , is that O.K?
Fuel tank breather?

 

Checked pipes at fuel pump end fuel is flowung freely upto and after fuel filter. Will check the fuek distributer tomoz and give that a good clean.

Thanks

 

Ok ive took the fuel distrubuter apart and cleaned everything inside cleaned all warm up regulator and put all back on car. You can see fuel going in and coming out of distributer but now the car wont run...turns over fires up for 2 seconds then cuts out..again any help or ideas greatful....

Thanks

Andy

 

Has it got a spark when it cuts out?I know its had a dizzy, dont just expect it won't be that.

 

Wonder if the hall sender is failing in the distributor....

 

Took each plug out and checked them all are getting good sparks. There deffo something happened since i took fuel distributor apart. Before that it did start and run just woukdnt go proper when accelerating. But would tick over for 30mins no problem no it wont even run....i have fuel going in and out of fuel distributor totally puzzled

 

If you manually operate the flap in the fuel metering head will it run???

 

Tried manually opening pkate still wont run....but if i take the fuel lines off and lift plate up fuel is rising out of all 4 ports evenly so fuel must be going thru
