yes 2 injectors and the 8th vin is Z

I forgot to tell you that. I have sprayed starting flued into the intake when it has done this and when i crank the motor it will sputter for 4 -8 seconds depending on how much starter fluid. So I would think it has to be getting spark right.

I can hear the fuel pump turn on when the key is turned. Even after it dies. And if the truck tries to run when starting fluid is sprayed wouldn't there have to be spark. With no spark it wouldnt try to start...
This only happens when truck is warm and driven for a period of 30 min to an hour. Then it takes 3-5 hours b4 the truck will start again. (cold start)

But what I mean is if the fuel pump is bad wouldn't it eventually not start at all. Like this truck only doesn't start after it dies. But will start again when COLD

So you deff think it's the pump. Not a relay or anything else.

Yes I understand about getting spark but I kno it is getting spark because the truck will kick over when starting fluid is sprayed into the throttlebody. But I just don't understand y it only accurs after the truck up to temp for more than 20 min while driving. But it seems it will run forever if just sitting at idle.

Hey when the truck dies it does get spark but the injectors are not squirting fuel. But is it common for a fuel pump to shut off after running and driving for an hour but then work again after sitting for 3-5 hours?

Hey I hooked up a noid light to the injector harneses and after the truck dies the light does NOT light up. So I'm guessing that means there is no power going to the injectors after the truck dies.

Thank you very much. I replaced the ignition control module after letting the truck die and it started right back up and runs fine. No more dying.
