Good morning! I am new here so thanks for having me! I have a 1995 4x4, 236k miles, and having a recent issue with stalling as if it’s run out of gas. Usually it’s after it has warmed up with some previous driving, in stop and go traffic, and often but not always when slowing down at a stop light etc. It also will cut out while driving. Were told it is probably the CPI (spider injection) system so we have the part and will replace it this weekend. Now, the fuel pump has made a loud whining sound since we bought the vehicle used a couple months ago, but it is always audible, we can always hear it engaging. Even so, since it whines, we’re going to replace it as well because I know that’s not normal. The temp is fine, oil pressure, etc is always fine. Any ideas?

 

Follow the tests in this link and post all 4 reading:

Thank you! Will get on that after work today!

 

The Procedures for your 95 are basically the same, but the specifications are different. Post all 4 readings and we can analyze them.

 

Thank you. I hope it's what we THINK it is and nothing complicated. It's our only vehicle so we gotta figure it out. I can limp it around town and pray it stays running but nah, would rather not lol.

Thank you again and will be in touch.
