95 Caprice Fuel Related problem

[blackEyeSSFly]

ok back to work on the car today...Ok so nothing has worked, I dropped the tank again and i check out the fuel pump and walllaaa one of the wires was off, so i pop it back in its place but before putting everythin back to together i wanted to make sure it would work...SO i turn the car on and it starts but then shuts back off again(i think the only reason it started was because of the lil bit of gas in the TB...Do i need to put the tank back on to make sure that its actually working because in the lil plastic part that goes from the fuel pump to the lines there is gas in it and when i started the car it bubbled up like it was flowing up through the lines ...or will i not be sure unless i put the tank back on and put some gas in it.

make sure all those wires are securely fastened in the fuel tank... put 3 gallons of gas or more in tank.... then turn key ignition on wait 2 seconds and repeat 3x then go for start.... make sure battery is charged... did you fix those vacuum leaks ..... check for other hoses broken etc.......??????? how was your key was the resistor ok?????

Does the resistor in the key just cut the fuel source off or the ignition and fuel? I don't know for sure but I always thought it interrupted the ignition source too. If what I stated is true, then it wouldn't be the problem since its got spark. Just a thought. I'm thinking its a bad ground or wire in the harness for the fuel pump by the tank. Figure its exposed to the elements so corrosion is possible. Easy to check. I always start with the simplest first. Change the relay for the fuel pump and check for pressure. If you have good pressure your injectors may not be firing. I know there is a way to safely check the injectors with out burning them out. If you dont have noid lights you can use a volt meter but not at 12 volts! The injectors have about 4 or 6 volts going to them. Maybe someone can help explain this better.

if the key is incorrect it will not crank no fuel pump and because its not cranking there wil be no spark.... as rotation is required for this to happen.....then after so many tries I forget how many then you will have to wait for some period of time before it will start when correct key is used... so even if you have correct key it will not start if you have exceeded the number of tries with bad key... these resistors in key fall out ,,,,most owners are unaware that it's a resistor ,,,think its a key ornament.........

I have someone coming tomorrow to do a bypass for the pass key and he will be checking for broken wires also and hopefully this is the problem

What does the fuel pump have to do with the motor cranking by the means of the starter? He said when he introduced gas to the TB it fired up until that fuel was burned off. That means there is spark.

this i believe is a female type .... and it was stated that she was told she had a key issue as well as this fuel pump /wiring mess then vacuum lines broken so this is where it's at now..........found wire off of the fuel pump in tank......

got it looked at and checked..the ignition was a problem..and some broken wires...the pcm was not getting the signal from the by-pass...but the tank was not on the car so we are going to put the tank back on and by-pass it again because the sending unit is grounded through the tank(from what he said) so when we put the tank back on and put the bypass on and see if that works...please cross your fingers for me on this one...im almost done...

Ok so this is where im at...
CHANGED FUEL PUMP
FUEL FILTER
FUEL PUMP RELAY...
Got it checked and was told something about some broken wires dealing with the ignition...Also when the pass key bypass thing was put in the pcm was not reading the signal from the by-pass(or something like that)...Guy was suppose to come back and check it out for me but he never called...He said in reality the car shouldnt even be starting because he was getting nothing from the ignition when he tested it, there are some broken wires he said...Ok so where does this leave me...I have some broken wires dealing with the ignition(how do i repair them), where do i get this by-pass thing that he had and how do i install it...and also he said that the pcm was not picking up the signal from the by-pass so it was not turning on the fuel pump(how can i fix that problem)...called dealership they told me to bring it over there and they going to charge me one hundred and something to put it on the machine and whatever is wrong they can fix it for a arm and a leg...

this sounds like someone reconfigured this starting system...wires don't just break.....I will have to think about this....dealer is out of the equation as the will charge for diagnosis and accomplish nothing... purhaps looking in phone book for a repair shop with good electrical skills in automove area call and explain....
