85 el camino w/ tpi

[caddymatty]

Hi everyone I am brand new to these forums and very wet behind the ears when it comes to working on cars. So of course I jumped right in and got a couple vehicles that I really love and I am going to learn this stuff if it kills me.

With that said the other day I picked up this el camino. It has a 1986 tuned port injected motor with the 90-92 speed density system. The el camino has no performance mods other than hedman full length headers and exhaust. As far as the installation goes the person told me that he put the tuned port injection fuel pump into the stock el camino tank. The truck seems to be starving for fuel when I try to start it and also when I come to stops.

When trying to start it I must put the key into the on position first,listen to the fuel pump pressurize then give it a try. It never seems to start for the first few times and everytime I must go back to off position, back to on,listen to pressure blah blah. It seems that it is a priming issue perhaps?

When I am driving down the road sometimes when I come to a complete stop it will stall. It seems to not be as bad when the tank is fuller but it still happens then once in a great while. Not sure if this is from sloshing in the fuel tank or some other reason.

I am not sure exactly where to begin but I want to try and problem solve this on my own. Where to start is the question? Do I begin with things like the fuel pump relay or is this just something a mechanic is better off problem solving for me.

Thanks guys I really love this forum been soaking up a lot of info.
