Engine Mechanical problem
1996 Chevy S-10 6 cyl Four Wheel Drive Automatic 188000 miles
I have recently took on a project of restoring a 1996 chevy s10 ZR2 pickup truck. I have just recently replaced the raidator supoort to a 1998 model, I had to replace the front cap and like the newer model front end. I dont know the history of the truck I tolled it home. I not very mechanically inclined that is to say I know very little about vehicles. Now to my question, I having problem with the fuel pump "I think" I have check the ECM battery fuse it test good Im getting 12 volts at the fuse box. I have check the fuel pump relay by switching it with the horm relay it check out good i'm also getting 12 volts thier to. I have unpluged the fuel pump module from the gas tank not sure what that does the book I have says it for fuel level sending unit and full pump 12 volt supply. Is that what send the imformation to the gas gauge needle on the cluster? And is that all it does? It also has a 3 wire plug on the fuel pump module "not sure what that does" I think it the power supply for the pump. Is this correct? I have check the power supply to both of these plugs and i"m only getting 6 volts unless I jumper a wire from the battery to the fuel pump test terminal then i'm getting 12 volts. I would like to know what prongs on the 2 plugs should be sending volt reading. That about all I know I would really like to exhast all other option before repalceing the fuel pump. I here so many comments about people replacing there full pump just to find out that was not it.
have the same problem?
