I would do it first.

Cap & Rotor
AC Delco Platinum Plugs
Plug Wires
PCV valve
Air Filter

You might kill two birds with one stone.

Sorry to harp, but most problems can be fixed by doing a complete tuneup.

You can get by without replacing the wires, but the cap and rotor and plugs for sure.

BTW, make sure you do one plug at a time so you don't mess up the wires.

First, clean your battery cables and test the battery. Low battery voltage to the fuel pump will cause the hard starting problem you've described, and a bad ground could be the cause of your other problem.

cool, just waiting for the weekend now, and hopefully some nice weather to work in. i'll definetly get the cap and rotor, plugs, wires. hopefully its not too expensive, money is a little tight.

then don't worry about the wires.

Get a new cap and rotor and plugs.

Make sure you use AC Delco PLATINUM plugs. Gapped at 0.060

I have a 2000 Blazer 4wd W engine 114,000 miles. I was having the same long start problem you are having. I just replaced the plugs, cap and rotor (all AC Delco) which seems to have completely solved that problem. I really can't complain since they were all original parts. I'm still having a few other minor issues with the engine performance, but the long start problem is solved.

mywintertruck,
I believe it was about $70.00. It was a few years ago.

Good luck!!

cool, thanks everyone. ill let you all know what goes on after the tune up.

Get AC Delco parts only.

[mywintertruck]

well i did my tune up yesterday, plus wires, cap, rotor. also had to do the back brakes, and drums. there was hardly anything on them. drums were shot. still having the starting problem though. so im going to save up a little more now, and get that fuel pressure regulator. oh well. i do say it runs a little better now, so the tune up was a success. thanks to all who posted

[BlazerLT]

Did you change the pugs?

[mywintertruck]

yeah, oops, i just saw, i wrote plus, instead of plugs. my bad. but yeah i changes them.

Before throwing parts at it check that fuel pressure first.

Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
Later V6 and V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel.
Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.
Post back fuel pressure readings.
