starts and stalls
I originally thought it was the fuel pump and did the following with
inconclusive results:
1)Turning the key on doesn't make the pump run but after trying to
start it I can hear it for a few second and I can hear it while it
lopes along on starting fluid
2)I couldn't get any voltage at the pump with the key on although I
didn't actually pull the connectors off to test.
3)Jumpering ports 4/6 on the relay didn't make the pump run.
4)For a couple of days before it died I noticed a high pitched humming
or whining coming from the relay/fuse panel...I didn't know what it was
at the time but I'm wondering if it was the relay. Although if it were
the relay wouldn't the pump run if I jumpered the terminals? PS I
didn't have spade connectors so I just shoved wire in the relay
terminals.
See what I mean about inconclusive results? #1 doesn't really tell me
anything, #2 and #3 make me think the pump is bad and #4 just confuses
me. I suppose I could run cables directly from the battery to the pump
to be certain it works...How does that sound?
I can't get the injectors out by hand and apparently need the 'special
tool' to pull them and check flow rates. I'm assuming/hoping that the
'cleaning' V-dub Folks performed makes that unnecessary....
I'd hate to blow a wad of cash on a new pump and find out that's not
it. Errr...where and what is a transfer pump(!?).
You guys rock! Muchas Gracias for the help!
