1994 Pontiac Trans Sport minvan hard start

Arleen Ramos’s question:

” Hi . Can you please help? We have a 1994 Pontiac Transport minnie van. It has always started on the 1st turn but lately it has to turn several times befor it starts. I know it’s not the altinator and it has a new battery, plugs and wires. It’s taking longer and longer to start. Also it has plenty of get up and go. It’s just starting it. Thank You Very much and God Bless You for taking the time.”

Answer:

Well, old age is catching up with your Transport (as it does to us all.) From your symptoms, you would have a problem in the fuel injection system. If you remember the olden days, we used to pump the accelerator on old carbureted vehicles to squirt gas into the carburetor. That would get it to start. In modern cars, this is done automatically by the fuel injection system WITHOUT having to pump the accelerator. So first, try pumping your accelerator a little as you crank the engine. If it starts right up then, you have a minor fuel injection warm up system problem. If you don’t care, you can start the vehicle that way ( I have MANY customers who have done this over the years.) If you do want to discover what’s wrong, it can get REALLY expensive and time consuming for such a minor problem if it starts with pumping. You would have to have the fuel pump checked for proper pressure and volume, you’d have to have the computer warm up circuits checked for proper operation, you’d have to get the fuel injectors themselves checked out, and you’d also have to check the entire warm up system wiring and sensors. BUT, as a wild guess, the pump could be starting to wear, so you might try changing the fuel filter first and have a test done on the fuel pump itself. I have seen pumps starting to go out act like that (they don’t work right when starting cold, but once they start pumping they work fine until they cool off again–pumps sometimes will break in this fashion.)
