Car Forum / Driving, Maintenance, Tuning / 4x4 Cars / August 200599 GMC Suburban 350 vortec, fuel problem
Would not start after work the other day. Changed fuel filter and fuel pump relay switch. Still would not start after attemting several times. Next day went back and it fired right up. I drove it about 40 miles to work and back home. No problem there. I took it about 75 miles down the highway and it died on me. Had to have it towed home. CLEAN the battery posts and terminal connections VERY WELL. old John Hello, Walden! You wrote on Sun, 14 Aug 2005 20:24:22 -0400: W> Would not start after work the other day.

With best regards, ajeeperman@comcast.net. E-mail: ajeeperman@comcast.net I appreciate your reply John. It is turning over. Do you still think that could be it. Yes, my 1999 tahoe would do the same, and turn over but not start. it would also stop while going down the highway with all lights coming on, and then restart and run . Clean the connections with baking soda, wire brush and then rinse with water. CLEAN EVERYTHING WELL I and several others i have advised did this and never another problem. old john Hello, Walden!

My Blazer has a "fuel pump test terminal" which bypasses the relay, your GMC is probably similar. If you hook 12V to that you should be able to hear the fuel pump hum. If not, replace it. -- spud_demon -at- thundermaker.net The above may not (yet) represent the opinions of my employer. |
