Rayman Posted July 4, 2008 Share Posted July 4, 2008 Help my car wont start, when i turn the key everything cranks up as normal but it just doesnt fire, all the dash lights come up as normal but it just wont fire up. Its not the battery or starter, evrything is normal in the starting procedure apart from the very last bit where it fires up. Last week i had a replacement fuel pump fitted, and i think this one is busted too. Its definately the pump as you dont hear it prime up neither. Any ideas what causing it to do this, and is the fuel pump busted or could it be a fuse or something? The first time i went to start it, it fired then died, then i had it fixed, it worked for a couple of days then when i went to start it yesterday morning, it wouldnt fire at all so obviously no fuel getting thru. If it is eating fuel pumps what would be the cause? Thanks Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 4, 2008 Share Posted July 4, 2008 Anything done to the ECU or fusebox area? Quote Link to comment Share on other sites More sharing options...
Scott Posted July 4, 2008 Share Posted July 4, 2008 check the EFI fuse. Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 (edited) Well i have this alarm toad ai606, its a long story but i drained my battery a while ago when i left my lights on, i went back to the car and obviously the car alarm went bonkers and i couldnt stop it so had to rip it out, now im left with no alarm siren. But its worked fine for ages like 6months like this, the alarm and immoboliser just dont work. The key fob doesnt do anything. It does flash the hazards tho when i start it up, still does now when i try. Edited July 8, 2008 by Rayman (see edit history) Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 check the EFI fuse. How can you tell when they are bust? Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 4, 2008 Share Posted July 4, 2008 Check the 2 EFI fuses and relays. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 4, 2008 Share Posted July 4, 2008 How can you tell when they are bust? If you look at each fuse, there is a piece of wire encapsulated inside, if its intact, its fine, if broken its broken. Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 Got AA here now, told him about the fuses, where are they located? What colour? Quote Link to comment Share on other sites More sharing options...

Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 (edited) Ok checked fuses, they are fine, checked power to the pump, he said that was fine, so the fuel aint getting pumped to engine, its almost like ive run out of petrol but ive not. Looks like the fuel pump is bust. But i just had a replacement, supposodly brand new, can something cause the pump to blow? Wonder if one of the wires could come loose after fitment, like when ive gone over a bump. Thanks for the help.

Spike3.0 Posted July 4, 2008 Share Posted July 4, 2008 Mine turned out to be the main relay - by ignition Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 Is that a relay in the under-dash fuse box? Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 4, 2008 Share Posted July 4, 2008 What does the AA man reckon? Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 But if the power was getting to the pump that would rule out any fuses/ relays would it not and mean its either the pump bust or a faulty pump connection. Or i dunno to be honest, havent got a clue. Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 What does the AA man reckon? He recons i need a new fuel pump, but ive just had one, well i think it was used actually as it cost £50. Which means is either bust again or faulty connection within the cannister, they are weird to wire arnt they? Something must be causing the pump to bust as its too much of a coincidence two pumps going within a week. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 4, 2008 Share Posted July 4, 2008 Was it the stock pump that went? What pump and where from etc? Quote Link to comment Share on other sites More sharing options...
Rayman Posted July 4, 2008 Author Share Posted July 4, 2008 Yeh stock pump. Hyper, lol yeh i know they had some bad rep recently, only place i know this close for the AA to take it to. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted July 4, 2008 Share Posted July 4, 2008 Oh god, its not there now is it? Id go for checking the pump, its fairly likely they have bodged it somehow. Check the pump wiring and the fuel pump ecu and then fit a Walbro, they only work out around £50 new anyway Quote Link to comment Share on other sites More sharing options...

Ian C Posted July 4, 2008 Share Posted July 4, 2008 Can you hear it spin up? Can you hear it spin for a second when you key off the ignition? Try taking the fuel return hose off the barb that comes out between runners 3 and 4 of the intake manifold and see if it spits fuel out. Also, and this one is easy enough, bridge +B and FP in the diagnostics port with a paperclip, and then key on the ignition. You should hear your fuel system run. Do that before letting monkeys near it. You have de-immobilised the car haven't you -Ian Quote Link to comment Share on other sites More sharing options...

No nothing Try taking the fuel return hose off the barb that comes out between runners 3 and 4 of the intake manifold and see if it spits fuel out. Will have a look for this see if i can manage it Also, and this one is easy enough, bridge +B and FP in the diagnostics port with a paperclip, and then key on the ignition. You should hear your fuel system run. Do that before letting monkeys near it. Right will try this. You have de-immobilised the car haven't you Yes it wont crank at all when immobolised, unless of course the toad has a fuel immoboliser of some description. Thanks BTW!
