I have a 98 Blazer that will just **** the bed for no apparent reason. Truck will start, maybe go 5 miles or maybe even 25 miles and buck a few times and just shut down. It will still crank but will not start. After an hour or so, truck will start and the process repeats! Has anyone ever had any problems like this? Any ideas or direction would be awesome.

 

I would start with a fuel pressure and leakdown test. Do the test witht the key on, engine off. Your initial number should be between 60 and 65 and not go below 55 for 10 minutes. Post back your numbers.

 

Im not a mechanic....I dont have a fuel pressure tester thing....Im almost certain I have an electrical issue.....Thanks for your help though...Its a 98 blazer...the tester probably costs more than the pos is worth....lol

 

You can rent fuel pressure gauges from auto parts stores. get your money back upon returning the part.

 

+1, if you have ever checked the air in your tires, its that easy. And why ask for help if you don't like suggestions?
