help. my pickup loves to run cold but not after its warmed up. here is what it is doing. after it is warmed up it starts to hesitate really bad, until it gets to the point where it dies. i can have the gas pedal to the floor with no effect. after it dies i have to wait 10 minutes, then it runs fine. if i just make short trips it never stalls. any help would greatly be appriciated.

 

What year B2000 truck do you have aechicken? Older B2000 had electric fuel pump and not mechanical style. How does the fuel pump pressure and volume look when it is warmed up and acting up. Should have 3-4 psi pressure and at least 3/4 quart per minute volume.

 

its an 86. i will have to check that out tomorrow and get back to you. any other ideas?
