len1 Posted April 17, 2018 Report Share Posted April 17, 2018 So my TR6 has been in bits for nearly 5 years...I am putting it back together now. I have a problem i think with the bosch fuel pump..its whurring away put alas no fuel coming through to engine bay....i was expecting it to work again,,,its all plumbed up as before (it did run 5 years ago ).there is a gallon of petrol in the tank. Any ideas or does it sound like pump has had it ? Len Quote Link to post Share on other sites
bluebob Posted April 17, 2018 Report Share Posted April 17, 2018 Hi Len have you check fuel filter ? try disconnecting supply to pump to make sure fuel is getting through as a friend of my had a similar issue we found fuel pipe had got crushed restricting fuel to pump, hope this helps ?

len1 Posted April 17, 2018 Author Report Share Posted April 17, 2018 thanks. i will have a look tomorrow, pipes are all new so maybe filter Len Quote Link to post Share on other sites
barkerwilliams Posted April 17, 2018 Report Share Posted April 17, 2018 Is there only one gallon in the tank? Depends on the tank but some outlet pipes protrude a long way into the tank. Does fuel flow if you ease the pump inlet pipework? Alan. Quote Link to post Share on other sites
k_raven_smith Posted April 17, 2018 Report Share Posted April 17, 2018 Are the wires the wrong way round? Quote Link to post Share on other sites
len1 Posted April 17, 2018 Author Report Share Posted April 17, 2018 thanks for replies' wires are correct ,have double checked petrol.... thats a good call ,,,actually it wasnt a full gallon i put in maybe 3/4 ,,,,,,hmmm hopefully thats my problem, i will report back in the morning cheers Len Quote Link to post Share on other sites
Mike C Posted April 17, 2018 Report Share Posted April 17, 2018 How high is the pump inlet above the fuel level? Bosch pumps have poor suction capabilities. Mine has a separate ( "Carter "manufactured ) primer pump mounted in the bottom of the wheel well to feed it./ Quote Link to post Share on other sites
len1 Posted April 18, 2018 Author Report Share Posted April 18, 2018 (edited) ok , so i have spent a bit of time looking for my no fuel problem.... its a wiring issue,,,,as Neil mentioned. Thanks. As a last resort i swapped over the white feed to the negative and vice versa.....it worked properly...so one thing fixed and now i need to search for the wiring issue..its a new loom . I have checked the pump wires and they are correct...it must be something i have connected up has caused this issue as the pump did work over the weekend but a flexi was leaking so i just carried on with other bits until i could get to a shop for the flexi. Thanks all for help as always much appreciated I am not happy with swapping the polarity around on the pump... (not a fix )..i have corrected it, and the pump is now going in reverse. i have checked the wiring loom and its correct ....i think a new pump is required..

Rem18 Posted April 19, 2018 Report Share Posted April 19, 2018 Generally if the pump runs its ok. They tend to leak over time I think. Least mine did. Good luck Quote Link to post Share on other sites
Steves_TR6 Posted April 19, 2018 Report Share Posted April 19, 2018 Bosch pumps are actually marked + and - so perhaps check the wiring is as you think it is. These pumps are not reversible, may run backwards but not designed to pump backwards! I have a spare 996 pump if you need to test Steve Quote Link to post Share on other sites
len1 Posted April 19, 2018 Author Report Share Posted April 19, 2018 Hi Steve yes i have seen the + and -.....have definitely got it wired correctly...a friend of mine popped by yesterday and he knows about electrics....he agreed i have it right , yet the pump is going in reverse.....I may take this opportunity to put a Lucas pump back on. cheers Len Quote Link to post Share on other sites
len1 Posted April 19, 2018 Author Report Share Posted April 19, 2018 Finally my problem is solved. I spoke to Neil this afternoon and went through all the problems .Neil suggested that maybe i had connected the pump and filter up the wrong way ,,,and of course he was right. Cant remember doing it but obviously i had ! So now the pump is blowing instead of sucking ! Thanks all and a big thanks to Neil Cheers Len Quote Link to post Share on other sites
