Title: Getting a motor running
Post by: gutts on February 24, 2015, 09:30:23 pm: Hello
I have been looking for a new used motor for a v10 pickup . A person I do not know has a 87 blazer that has been sitting a little while , not very long . He has stated that the thing needs transmission and brake lines . I know this a common problem , in the "rust belt .
The rub is it needs fuel pump also . Is there a way to get this thing running , for a few minutes , just to hear the motor run ?

Post by: gutts on February 25, 2015, 05:54:22 am: Yes I understand . It is a TBI . I should look for a 18 PSI pump .
We have two feet of snow here so , no hurry , just trying to think ahead a bit .
Thank you

Post by: gutts on February 25, 2015, 03:45:17 pm: Alright that great info . I will find the relay on my truck and look it over so , when I go to look at this one , I will know just where it is . Is it common for the relays to fail ?

Post by: Irish_Alley on February 25, 2015, 05:30:31 pm: I wouldn't say common but can happen. Sometimes they don't get energized by the ecm due to other problems. But its real easy to bypass so might as well try

Have run a motor a few times by putting a rag over part of the carb or TBI soak it with gas, it will run for a minute or two, longer if you keep the rag wet.
