i found out what the problem was. you would never believe this. i had two different mechanics
replace the fuel pump twice. i took down gas tank, emptied it was much as i could. its attached by two straps. un plugged all wires and hoses. pulled fuel pump out of the tank. (its inside the tank).
there is a metal piece on top where 3 hoses go. one is the main gas line to the throttle body, other is the return line, and the 3rd i believe is for the floater, to tell you how much gas in the tank. between this piece and the fuel pump there is a gas hose about 1 1/2" long. this hose was torn/cracked. i couldnt believe it with my own eyes. off course no one has this hose, so i took a piece of gas hose & cut it to size, installed with 2 brackets(it didnt have brackets)...i wanted to make sure that the connection was good. connected everything back up and did a volume test on inlet line at the throttle body...and wow..i have gas now. put everything back together...car started right up. nobody could find the problem...a guy who i paid $18.00 online helped guide me to the problem with the volume test. his name is Tracer at www.justanswer.com
he is still helping me fine two my caddy. really cool guy i spent so much money throwing parts at this car...now i know that this site is for real. you dont have to pay them until your satisfied. dont buy a fuel pressure gauge...i did that and now i am out $60. on these cars there is something that doesnt allow you to do a pressure test at the throttle body. volume test is better. disconnect fuel inlet line at throttle boday. attach a hose with a clamp to the inlet fuel line at the throttle body. get something for fuel to flow into. turn on key for exacly 15seconds then turn key off. measure how much fuel you have. you show have about a pint of fuel. if you u dont, then you have something faulty in the fuel system. i check the relay and fuse right under the dash close to the steering column. there is a small box with a few relays and fuses. this is not the main fuse box. i took it down (2 torx screws) , took apart the back of it to test relay..fuse you can test from the front...its a 10 amp fuse.. the relay is the second relay from the driver door front left to right. these were fine. there are 3 wires at the tank. a ground (black) a green wire power (12volts)..and i think a orange or pink wire...i believe this wire is to tell the instrument panel how much fuel you have... i tested connections at the tank with key on. i had power and ground...(to test the fuel pump, i did use a fuel pressure tester) i rigged up the fuel pump in a bucket, connected the wires back up..and the pump seemed to work, but not that much pressure, when i looked closer i noticed that the hose was torn/cracked. replaced the hose and tried the test again, and got 12lbs of pressure... put fuel pump back in tank and put everthing back together and problem fixed. i didnt have to test pump with fuel pressure tester, but i had already bought it. now i just need to adjust the idle speed control..its clicking. same guy say they are tough to adjust..he said it not that easy even for him. hopefully we can get that resolved too.
