QuestionThanks for the advice, but it didn't work. I tried disconnecting each injector and different combinations of injectors, but no such luck. I removed the fuel pressure connection cap and it started hissing. I took off the fuel filler cap and tried starting again. No such luck. I heard hissing coming from the fuel pressure relief connection at the fuel rail. I used a screwdriver to press in the fuel pressure relief conncetion and only air came out. No gas. I removed a gas line and carefully squited gas into the rail while pressing the fuel pressure relief connection to fill it with gas. I replaced the gas line and tried again with the same results. I checked the air filter and snorkel to make sure no critter had blocked them and they were fine.
I failed to mention in my first message that I had to disconnect and reconnect a vacuum hose. I also checked all fuses and they were fine. The gas tank is not empty, but it is low (enough to drive ~30 miles at least). Any more suggestions?
Thanks,
Johnathon

Greetings Sir,
I have a problem with my 89 Buick LeSabre 3.8 3800 v6 that hopefully you might be able to help me with. I had a fuel injector that was leaking badly, so I decided to change the o-rings on all of them. The problem injector was different from the others for some reason.
I disconnected the battery, removed the cover over the fuel rail, relieved the fuel pressure, disconnected the fuel lines, disconnected the wiring to each injector, removed the four bolts holding the fuel rail down, and removed the fuel rail with attached injectors. I installed the new o-rings and reassembled everything.
I turned the switch to on for a few seconds and then turned it off to go check for leaks. I then left the switch on while I checked for leaks. There are no leaks and I can hear the fuel pump like normal when the switch is turned, but the car will not crank. If I let it sit for about a minute and try again, it will fire up for a split second, and then go dead. I'm no where near being a mechanic, but I assume it's not getting any gas.
I had to park the car facing slightly downhill, so I though some air might be trapped in the fuel rail. I relieved the pressure again, and some air bubbles did come out, but the car still will not crank. Patting the gas pedal before or during cranking has no effect.
When I parked the car, I left little gas in it because I was afraid some someone trying to steal gas. The gas gauge says slightly below empty, but I assume that is because the car is parked downhill.
If you could shine a little light on my problem I would greatly appreciate it.
Thank you for your time,
Johnathon

Hi,Johnathon
What has me suspect is the different injector,the computer {ECM} controls the injectors by grounding the ckts,if an injector becomes shorted or fails internaly the ECM will turn itself off so as not to burn itself up,it uses a system of solid state relays call massdrivers,like an internal reseting fuse or ckt breaker,if an injector shorts out then that massdriver will close itself,thus it will not make the injectors pulse or come on,try disconnecting the connector at that different injector,and attempt to start the engine,if it starts and runs then that injector has failed,if still no start,disconnect another and retry starting it,let me know how you make out and ill help you in further diagnosing the problem.Thanks

AnswerHi,Johnathon
I think you may be out of gas,parked on the hill the little gas you have left has now moved to the front of the tank away from the fuel pump,add a couple of gallons of gas,or attempt to move the car to a level part and restart.
