Post '96 Astro hard starting

[drew300]

I'll try again. I guess I didn't do this right the 1st time
As a 2nd vechile, my '97 Astro will sit awhile better runs.
It iwas always hard starting if it sits a week or so, but starts fine if I run it everyday.
I read that the fuel pump will run only 2 seconds with the engine not running. (some sort of safety interlock).
Now, I turn on the key, wait for the pump to stop, turn the key off, then on, wait for the pump, sometimes I do this a 3rd time. Then, when I try to start it, it starts fine.
I have previously changed the fuel filter, which was partly plugged, but this didn't help the starting problem.
Maybe this will help at least some of the hard starting ones.
Now I trying to figure out if this a pump problem, or a regulator problem.

I had the same problem and had it diagnoised as a pump problem. I was told that the pressure HAS to be 60 psi. By turning the key several times you eventually build up the needed pressure. The pump should also be pulling around 9 amps if it is running right. I had to get new pump--not too bad of job to do yourself if you're handy with tools.
