20v conversion problems

[iflorey 0]

Hello one and all!

i am nearing the end of my 20vt conversion and tried to fire her up today.. The problem i have is fuel pump related. When i turn the ignition on, the lift pump primes, but i get no fuel to the rail! i have checked the filter and removed it to see if i had fuel flow but still nothing. is it the lift pump not fiilling the resevoir, the main pump not running or the accumulator blocked?

 

Any ideas? Dont want to splash a load of cash on the wrong thing.

What age car is it, does it have the twin fuel pump set up, ie lift pump and under body pump, or is it the later type where it is just the in tank pump?

its an early one with seperate lift and main pumps. Like i say, when i turn the ignition on, the lift pump runs nd i can hear fuel swishing around the tank, but no flow from the main pump through to the filter and beyond.

Sounds like your main pump is goosed. Before assuming this though check you are getting voltage at the pump, could also be the connections are mega corroded.

thanks mate, ill check it tommorow. got a few prices in today for pumps, they range from 60 to 200 quid. if i need one, i was going to go for a bosch at about the 150 mark. Also spoke to ben from Quantum today, he told me i can bin the accumulator if i want as its only there to aid starting on the old kjet sytem!

found the main pump seized solid. have ordered a bosch replacement. Managed to break a fuel line getting the pump out. I guess 20 yyears of road salt has played its toll on the metal lines under the car!

Thanks for the advice.
