New plugs and wires were put in. Once started will keep running.Believe it's fuel pump related
I would check the fuel pump relay first. You should have some fuel pressure in the lines when you turn the key on. The relay is powered for 3 seconds to boost pressure until the engine starts.
The relay may not be working or the check valve in the pump may be letting fuel back into the tank which would cause the pressure to drop to zero when the engine is off. You should have at least 15psi with a TBI system and 35psi with MFI.
I also believed it was fuel pump related. My father-in-law changed the fuel filter.He said always start with the cheapest solution. Next would be the fuel regulator valve. Contrary to what I learned on the internet it's actually located "under" the engine block. New fuel filter would be the last resort. Filter cost $15, valve cost $50 new pump around $275. He said always start with the cheapest solution first.. Thanks for your help. Vehicle problems are not as easy as they used to be.
All you guys(gals) were great but this guy( he's 76 years old) is the best I have ever seenHe can fix anything but his specialty is cars/trucks. He said the only thing he can't do is overhaul an automatic transmission. Geez that's it?

check the spark plug and ignition coil
check also your battery corroded terminal
check also the carbulator

Have the fuel pump checked for fuel pressure. Sounds like you got residual pressure but not sufficient running pressure.

Fuel pump needs to be more pressure than this.
SOURCE: Motor will not start hot
What was done that seemed to help? How many miles are on this vehicle?

did u check to see if u were actually gettin fuel..ur filter might b clogged..and did u replace the button along with the cap and rotor..and did u check to make sure u got spark..it might b the coil..they go without any warning
