| | | 1991 Chevy G30 Cranks but no start | Joined: May 2018 Posts: 1 stranger | OP stranger Joined: May 2018 Posts: 1 | I have a 1991 Chevy G30 5.7 van. When I drive it for awhile and shut off for a bit, like to go eat, then come out it doesn’t want to start. It would eventually. I changed the fuel filter, pump, and now the pump relay and it doesn’t what to start. After I changed the relay it started and then I let it set and it doesn’t want to start again. It doesn’t sound like the pump is running now either. What else do I need to be checking? | | | Re: 1991 Chevy G30 Cranks but no start | Joined: Jun 2010 Posts: 18,286 Likes: 558 | Joined: Jun 2010 Posts: 18,286 Likes: 558 | Welcome to the site Samantha ...check all electric connections for corrosion, that white or yellow powdery stuff, the battery cables & the starter end of those cables. Do you have power to the rest of the van when it doesnt start
Under the distribution cap is the coil a flat black item with 2 plugs on it, may need a cap & rotor but I bet the coil is on its way out. .
Again welcome

Really, I was as surprised as you will be. | | | Re: 1991 Chevy G30 Cranks but no start | Joined: Nov 2013 Posts: 2,286 Likes: 153 veteran | veteran Joined: Nov 2013 Posts: 2,286 Likes: 153 | Hi Sam, astarfitter, Welcome to the Site. astarfitter, frscke1 are correct Z are fussy, they will not run with a bad cap and rotor. Mine would not even start. 30 year old plug wires might need replaced as well. Good you R&R'd the fuel pump too.

On my 1991 G20 van when I purchased it, I too had to replace the fuel pump and filter. The one thing I did notice on close inspection was that MICE had chewed away at the fuel pump wiring and I had to splice new wires in place. Did you check close the wiring. Only takes a slight movement for the wire to not make contact and NO PUMP.
One thing you can do is "leave the dog house" off and drive it for a while and then when you go to restart you have access to pull the air cleaner cover off to see if it is getting fuel.
Not a big fan of intermittent issues like you have, course I don't know anyone who is through either.... | | | Re: 1991 Chevy G30 Cranks but no start | Joined: Sep 2005 Posts: 9,855 Likes: 234 carpal tunnel | carpal tunnel Joined: Sep 2005 Posts: 9,855 Likes: 234 | This post is over a year old......... just sayin' | | | Re: 1991 Chevy G30 Cranks but no start | Joined: May 2018 Posts: 2,397 Likes: 64 veteran | veteran Joined: May 2018 Posts: 2,397 Likes: 64 | That's a lot of cranking must have a nuclear battery.😂
