Subject: Long cranking after 9000T fuel pump replacement


I replaced the fuel pump on my '90 9000 turbo six months ago. The pump died suddenly. Ever since there is a delay before the engine starts - I have to crank the car for several seconds before the engine fires. Now that winter is setting in the cranking time is getting longer and the battery is suffering. I have been trawling the newsgroup for ideas but have not found an answer. I have a couple of ideas which I hope someone can comment on before I tackle the dreaded plastic fuel pump retaining ring again: 1) I may have switched the fuel lines round causing the non return valve to become useless. The reason I think this may be the cause is that there is an insert in the return line in the boot and nothing in the feed line. Does the return line have some sort of anti syphon valve or is the insert I am seeing the non return valve? Would the engine run in this state? 2) I may have lost the non return valve. When I pulled off the feed line it was very tight and the non return valve may have fallen out and landed halfway along the street (this is a long shot I know). Is the valve this loose in the fuel line? 3) The old fuel pump may have included a non return valve and my replacement does not? I did replace with the same Walbro pump but it was not new. Any other ideas? Thanks, Dave. d_a_v_er_a_m_s_a_ynopsaml_k_2_1.c_o_m
