Ok so this has been driving me nuts! My s10 blazer will never start on the first try when I turn it over sometimes it will start on the second try but usually its the 3rd try. today I tried 40 times and it wouldn't I could spray starter fluid into the intake and it would try then fail I did notice this time that the gas gauge said empty so I thought someone had taken my gas so I put in 5 gal and the needle didn't change, In the proses I drained my battery  so I decided to charge my battery up and when I tried again a few hours later the gas gauge came up and it started right up. what is going on? It has the 4.3 l engine

check basic tune up items, plugs, wires, cap and rotor. Then if that checks out you need a fuel pressure test done. Sounds like a failed pump, could be the regulator tho

I gave it a tune up less then a year ago new wires and plugs I do not believe there is a distributor cap I could be wrong just seems strange that if I put a battery charger on it will start just fine.

    My 88 Blazer will not start. If you jump the injections with the battery it will start and run. Can this be anything other then the ECU?
