Envoy will not start what could it be?

Any of your wire connections corroded? Ground, and battery wiring and starter cables wiring? Make sure they are clean and have a good connection and contact.

Do you hear the fuel pump prime the system when you hit the key ? Things need to be tested before you go out and buy parts you don't need . You could have bought a fuel pressure gauge and multi meter with the money you spent . But if you have no knowledge of how to use them then maybe you should take it to a shop so they can rip you off .

@Beatupchevy well the alternator was tested and it was bad battery I was due for a new one but yeah I see what your saying but the only shop in town is a complete rip off went in there cause car was over heating they messed with it when I got it back it was idling bad they tried charging me $855 and a week later it was doing it again I told them I wanted the old parts they replaced he said they had got rid of them

@VROOM12345 you know what I haven’t even checked last night I was just trying different things but this morning I’m going to do that thanks

It's the world we live in , no one can do their job , everyone's an @$$hole , and you can't tell them anything . These mechanics know cars inside and out , they can pull one wire and cause problems like that , they can not be trusted , but you already know that .

Yeah exactly I looked at my fuse box under the hood some of my relays were missing I went up there raised hell and had the cops called on me didn’t get into trouble but had to leave but they not getting paid they can count on that.

@Bob ok I just located it I’ll try that next thanks
