just last week i replaced the alternator, it was running fine till today...my car chokes when i turn it on but it doesn't stay on unless I step on the gas...when i take my foot off the gas it shuts off.

 

it might be your coil or distributor' plugs or cables'

 

ok think i think i found the problem on the top of my in line six theres these sensore that are in a row' well the wire was pulled off so i was gonna clean an an plug er n

 

I have a 93 new cps, new fuel pump new fuel injector orings I seen all injectors fueling the ports when I had the rail out and my spark is good at the distributor cap and at the plug wire , I have fresh gas junkyard extra computer , I am stumped. So fuel and spark but no run any guidence , about to try new distributor and coil

 

Let's start from scratch, what is the fuel pressure, in PSI?

 

38 to 40psi in prime circuit
