Default Re: Is it my fuel pump?

geasson, You did do a good test, but need more info. If you still need help, please answer in order and completely:

1. What V6 is it (cu in and letter designation)? I see a 305
2. Did you have motor running before parked long ago? When was last time it ran?
3. Have you replaced fuel pump? When?
4. What is part number of pump you have? you didn't say if it was new.
5. No, you don't want an electric pump.
6. You say you "went to work on it"......why? Did it not start or what? Are you trying to start the motor?
7. What is the history of this motor? I read your posts, only 5 posts in 7 years.
8. Were both the crank test and the hand test done with the truck gas tank hose/line attached to pump inlet?
9. Were both the crank test and the hand test done with the truck outlet hose/line still attached to pump outlet?

10. Where are any and all fuel filters?

Damage can be done to any motor that has been sitting a long time, without using correcting start-up procedures. Be careful.
