I'm guessing that there's no way of making a fuel injected system work from a mechanical pump and avoid the whole intank non runner scenario?

i think the pressure wouldn't be enough to keep up with the pump that squirts it through the injectors .
the mechanical pumps depend on the petrol stored in the carb to make up the differences in engine speed as they are directly driven by it ,i expect putting your foot down has a lag producing the fuel needed which would not be liked by a injector system as they work on higher pressures. theoretically you dont need an in tank pump just a powerful outside one to suck the fuel out fast enough.my MK2 espace (horrid car) also G reg never had an in tank pump only an external one ,i presume (will await for more experienced members) a sender from a carb version and an external pump would work ????????????

First things first
Check the battery connections are tight - slacken off the bolts and re-tighten them and do the same for the other end of the earth(ground) lead; and check the engine earth strap that runs from the cam-cover to the engine compartment bulkhead (firewall) is tight. Then try starting the car again, having first charged the battery if necessary. It might also be worth checking the starter motor connections are tight at the same time.
Further diagnostics are dependent in part on the engine - B200 or B230A or E or F (A models are carburettored, E and F models are fuel-injected) - as there are different causes and cures for the two groups. If it's a A model it won't have an electric fuel pump as standard, but someone has fitted one.

Fuel pump and fuel relay replacement
Hello,
Just replaced my two fuel pumps and both are quite accessible and trouble free changes. I did lose a few bits into the tank trying to put the thing back in, as a real tight squeeze, but found a fish tank net an excellent retrieval tool (though a child's arm would be even better, but tricky with social services), before trying again and again. Working with the tank open isn't such a risk as you would think, just as long as you have the battery off and don't use any electrical kit near the hole. The fuel will likely become contaminated if left in open air for long. I left mine open for a week and it didn't smell any more, but it also didn't work as petrol any more too :-( I think the vapour part of the petrol must be pretty important, so have gone and got a couple of cans of new petrol to fill it back up now. If I remove fuse 4 I get no sound from the tank pump, but if plugged in is does buzz faintly, I would like to put some tubing on the outlet to see if it squirts out petrol, but am pretty sure this little pump is working ok. Since replacement however, I still have a very warm (hot even) fuel pump relay and fuse 6, not sure if this normal and get the feeling they will melt given time, so still at a loss. So I have ordered a new relay and new fuse assy with modern fuses, plus will check the earths by the fuse box and under the rear seat. A clamp ammeter maybe good for fault finding if I can find one that works with DC? Any advice if those have similar issues would be helpful. |
