Hello,

Ok, a lot more info will be helpful.....As much detail as possible...

When and how did it stop running?

What have you done?

i put the crank senor in it new plugs an wires nw disterbotr cap and roter on it we got good spark and good fuel pressure wat else could it b

also it started yesterday and then the smoring we went out and it wouldnt so we tryed all the things i just told u

Agian - When and how did it stop running? were you driving it? did you go out one morning and it wouldn't start? Did you drive it to the store and come out and it wouldn't start?

Is engine light on?

no the engine light is not on and we went to the walmart and then it started running like it wasnt getting power then it started running good brought it home parked it went out the smoring and it wouldnt start

u there

Ok, when you put the new Cap on did you make sure the Firing or was correct. In other words, did you replace the cap and rotor first and leave the wires on the old cap and moved one at a time from old to new placing wires on correct tower.

yea i did all that

wat else could it be?

u there?

Also you said you had good fuel pressure, what was the pressure and did you do a leak down test?

wats a leak down test?

Once fuel pressure is tested turn key off watch fuel pressure for about 2 minutes, pressure should only drop about 1 - 3 psi. If drops more or drops as soon as key is turned off the fuel pressure regulator is bad and will need replacing.

ok and if it aint that wat else could u suggjest

Oh, to make sure and since you didn't say anything on the firing order diagram, you vehicle is a 4.3L V6. I as cause you have that is a 4 cyl 4.3L

its a v6 4.3 2000 chevy blazer 4 door 4x4

if it aint the fuel pressure reglator wat else could it be?

Well if all else checks out then it is a good possibility that the Fuel Injection Assembly or as some mechanics call it the Spider Assembly has gone bad. Check out pic. It is located under the Intake.

is that hard to change and wat do u think one of them run? and if it aint that could it be somthing else?

Only one other thing comes to mind, and that you did check. Cylinder Compression. Which could indicate a Blown Head Gasket.

Check your Oil - Does it look like Milk Chocolate? If so good indication of blown head gasket.

Check for Oil in Coolant - another good indicator.

Check out link below for how to check compression

Sorry go to get to bed have to work EMS in am. Hope this has helped some anyway.

Checking to see if you were able to do the compression test and check the oil and coolant.
