Unknown Problem

[TW1ZT3D561]

ok so i've been to 3 different automotive shops and none of them can figure it out.

 

so my next step is you guys i hope you can help

 

i have a 1997 GMC 1500 2X4 4.3L V6

 

symptoms:

 

doesn't start (or takes a VERY long time to get started)

but once its starts once, it fires up every time first try every time after that, unless i let it sit for 5 or more hours

then it doesn't start again.

 

i changed the battery and for some reason it started right up

didn't change anything but battery

 

then i let it sit at shop over night to make sure it started up the next morning after sitting for awhile

and to no ones surprise it didn't start up.

 

so i fiddled around with it some more and ended up taking off the distributer cap.

didn't replace it or even clean it off( it as replace about 6 month ago)

put it back together and it started right back up once again.

 

so again i let it sit over night at the shop.

came in this morning and it didn't start?

 

if i let it crank over for a few seconds and turn the key to the off position the motor spins backwards (like some old fords use to)

 

i ran a scan on it and nothing came up, there is no check engine light on.

 

if anyone has any ideas as to what it may be please let me know

or if this happened to you, let me know the solution

Fuel pump losing pressure or something? It's just a guess I'm no specialist.

Has the fuel filter been replaced recently?
