1995 Chevrolet Tahoe Q&A
1995 Chevrolet Tahoe Question: why does my 96 tahoe turn over good but it will not start?
it is a 96 tahoe, 5.7 l v8. sometimes it starts great other times it wont start at all. i replaced the fuel pump module and the fuel filter. the first day it was great . the next back to having trouble.turns over hard but just wont start. i try cranking it until i finally drain the battery and have to jump start it. soon as i hook up the cables it instantly starts up. why does this happen and how can i fix it? - chevymain
When it dont start up need to check fuel press. and ignition fire. Bet you dont have one or the other or both. Can you hear the pump run when it is not starting? Crank, let off key but leave it on, does pump run a couple of seconds? Can repeat this as many times as needed to see if pump is working. If that is ok check ignition fire if that is ok injector pulse should be too, start engine and drive away. I assume you can do this as you said, "I replaced fuel pump module and filter". - pushrod
have fuel pressure tested,it may be on the low side of spec's - globalhelper
