Re: After driving car for 7-10 minuts...
The secondary pump comes on when the secondaries are activated for full power (all 16 injectors).
No need for the secondary pump to operate during normal driving. You need to 1. check for stored codes 2. disconnect the battery for a couple of minutes, then re-connect to clear stored codes 3. drive again to re-create problem 4. check & record stored codes 5. bring the info here for review You probably have a secondary opening problem

Re: After driving car for 7-10 minuts...
Update:
After removing pumps, i checked the Strainer were damged and clearly seen open from the ring. WHY?? look at picture!! It has been 1 year since these orginal GM pumps installed on my Z. the dirt and muck block out the main pump inlet port, i clean it, but the pump is already Bad...i think both of them. So i decided to order new pumps. I think it will be good idea to replace the Strainer frequently! Here is some type of Strainer to buy http://store.getgmparts.com/fuel-pumps.html WHICH TYPE IS THE BEST?? Last edited by HADI-ZR1; 09-25-2010 at 05:05 PM. |

Looks to me like you probably need to clean out the fuel tank too.
