Question about 2001 Chevrolet Blazer
I need some information regarding a situation with a 4.3 Vortec engine in a Chevy Pick-Up. The engine started hard, which was an indication that the fuel pressure relay was faulty or weak, and as a result, would not achieve a speed of over 50 MPH on the road. This seems peculiar due to the fact that the oil pressure relay is supposed to act as a backup for the Electronic Fuel Ignition system in this particular set-up. Once the oil pressure achieves a safe level, the oil pressure relay has the ability to take precedence over the EFI. The fuel pressure relay has since been changed; the problem that I have is that I have been told that a faulty fuel pressure relay can render and EFI system useless. I find this hard to believe due to the fact that the oil pressure relay is able to function as a back-up in this situation. Any suggestions? were is the oil preesure switch located?
