Its not throwing any codes was getting a code for the map but we put a new one in. starts right up fp primes to around 50 then after about 2 or 3 seconds jumps to 35 than consistantly falls till it dies. replaced the pump still does it. replaces the fpr still does it. checked for vac leaks. tested the voltage to the pump switched out the map with a known good one still does it. any help would be great its running pig rich when it starts...burns your eyes. Would a bad computer cause the fuel injectors to stay open at all times causing it to loose pressure??? ANY HELP WOULD BE MUCH APPRECIATED. THANKS, BRANDON
