van is hard to start when hot or running for awhile, its an 89 318 tbi. starts fine when cold, but when hot you have to pump the gas or hold it down abit to get it start up? any suggestions ?

Pumping the gas on a fuel-injected car does absolutely nothing, as there is no accelerator pump. Holding it down fools the MAP sensor into a faulty reading when starting the car. How does it run when it finally starts hot?

Check fault codes and report back. http://www.allpar.com/fix/codes/index.html

ahhh runs good, it is burning some oil i noticed it smoke a lil on one side, of the exhaust there is dual exhaust on it. i replaces a fuel injector not that long ago.

It does sound fuel-related if holding the pedal down helps it start. Too much fuel (rich) needs the extra air provided by an open throttle to combust. Diagnose for a fuel hot-soak issue.
An injector that drips after shutoff is possible. A fuel regulator problem is possible (check fuel pressure). Vapor lock is possible if pressure in the fuel line drops after shutoff.
Pull the doghouse and air cleaner for a look. Fuel pressure is checked by tee-ing in a fuel pressure gauge.

And let us know if any fault codes are stored.
