To start the 4.3 liter in my 2000 astrovan I have to pulse the starter.
I engage the starter for about 2 seconds, than again and by the third
pulse its running fine. To test the fuel pump I've turned the key on
and off and on and off, well you get the idea, but that doesn't do it.
I've got to actually turn the motor over for a second or two. If I
grind on the starter it just won't fire. I was thinking maybe a bad
battery was the cause but on the pulse that starts it it starts on the
engagement of the starter, not when I disengage it. Until I discovered
this starting technique a month or so ago I thought I was never gonna
get it started. But the pulse starting technique works so well I've
kinda lost interest in fixing it, not really. It runs well. I've
recently changed the fuel filter and I can accelerate to 100 with out a
cough although I think the mpg is down (nothing to do with the filter
but with whatever is wrong making it start hard is also affecting the
mileage). Its hard to tell though, winter and all around here you know.
Anyone got any suggestions about my starting issues.
