[urq] Another stumbling problem!

[Brandon Rogers]

Have you relayed the fuel pump? i.e., are you getting good voltage to
the pump?
How old is your pump?  I don't know the flow quantity - sorry.  If
nothing else you could swap in a known good...?  Too bad that is easier
said than done...

I don't know the fuel pressure specs offhand but 95 psi sounds close.
If youcan hook up a fuel pressure gauge and comapre to Bentley or IST
docs - tha would be ideal.

Does anyone know the flow quantity of the fuel pump in the 83 urq? I am 
advised by the mechanic that the car is running at 6.5 bar main line 
pressure, regulated at 1 bar cold and 4 bar hot.

Had the fuel tank relined and the lining broke down and deposited crud 
through the system. Have replaced both filters, cleaned and flushed 
injectors, replaced the warm up regulator, cleaned and flushed the fuel 
distributor, still getting a stumbling when engine is loaded as though 
not enough fuel is being supplied.

Any thoughts?

John
