I have a 91 suburban and it wont hold idle. I am waiting for and egr valve. if that fixes it i will let you know. I was told that they can have an internal vacuum leak therefore being difficult to detect.

Our F-150 had a similar problem. It was a cam phaser, then timing sensors, I believe, had to be changed as well.

If vehicle attempts to start but wont stay running at first and then just wont even start. You may as well break down and change the pump. But any other info will help me help you.

91 camaro won't start 3.1 6V. Changed fuel pump, injectors, & ICM, has spark & will start with starting fluid, then die. But will not start and run. It cranks over, but won't catch. Security light...


Is the fuel filter ok? - fuel pump ok? Sometimes a new fuel pump is faulty. You may need to check your fuel pressure. Could even be a plugged fuel return line. PS be careful using starter fluid - it can be hard on an engine. Le t m e know. Thanks

I wonder if my suburban 91 has any fuel filter before the fuel pump (between the fuel tank and pump) that would be changed sometimes in a while.


according to advance website your fuel pump is electric and inside the tank. the only pre-filter is thus the screen around the pump inlet. years of detritus can collect around them, but you are going to have to lower the tank and pull it out to see. it is 20 years old and a replacement would be in order anyhow if it has never been changed before.

Check fuel pressure, if its not 60psi, you need to replace the FUEL PUMP, and filter

My suburban will not start its like its not getting fuel


Try replacing the fuel filter first and checking the fuse and relay to the fuel pump. You can get that information for Auto Zone where you can pick up the fuel filter too. Good luck and hope this helps. keep me posted, be glad to answer any questions you may have.

91 honda civic dx. Starts, runs for a few seconds then stalls


Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.
