91 Cutlass Ciera not starting - no fuel getting thru injectors?sherman42 07-20-2008, 01:17 AM 1991 Oldsmobile Cutlass Ciera, 3.3 v6, 243K. The car acted like it starved for fuel, would not accelerate but did idle. After shutting off, would not start. Started to work on it 36 hours later, it started, made 2 laps in circle drive, opened hood & revved engine - ran approx 5 minutes fine. Shut off, restarted immediately with success, revved some more, all seemed good. Shut off, went in house 30 minutes, came back to start it & cranks good but won't hit a lick. Has not started now in a week on it's own.I say on it's own because it will start & run for few seconds if I put gassy rag in air filter chamber. No fuse problems at fusebox, 42 - 44 psi fuel press. at schrader valve, great spark. sherman42 07-20-2008, 01:40 AM I disconnected battery to allow computer reset. No luck. Installed new computer ( yes put my mem-cal in new computer also) no luck. Went back with old computer then. Today put new CPS (crank position sensor) on - did no good. Also put new timing chain + sprockets on while had harmonic balancer off. Chain not broken but 243k I thought it was good idea to change out those works. Did the gassy rag in the air filter chamber again with same res ult as previously posted, starts + runs few seconds, then starves for fuel. Any ideas ? I would appreciate your replies- thanks. maxwedge 07-20-2008, 06:22 PM When it stalls you have 42 psi? , if so try disconnecting the maf and see what happens. sherman42 07-21-2008, 02:45 AM The car is broke down at my in-laws home 10 miles away. Will try disconnecting MAF next chance I get over there. I had that apart today and cleaned it gently (didn't look bad but read that it can cause some problems so I tried cleaning it) which did not help. That is the sensor near the air filter housing? Looks like 2 small filaments when removed from it's housing? Hope thats right. Have only checked fuel pressure with key on, car not running. Thanks for the reply, will try disconnecting that & see what happens. maxwedge 07-21-2008, 07:10 AM Check the FP during the crank no start issue. sherman42 07-22-2008, 12:51 AM Checked fuel pressure again tonight. 40 - 42 psi during cranking. Good volume also. Unhooked MAF sensor and cranked engine, still no start. Also want to say I have checked several times to see if any SES codes and always just get the 12 code as book says I should. maxwedge 07-22-2008, 03:49 PM If it will not start with starting fluid, you do not have sufficient spark. Or the engine has internal problems such as the T'chain. sherman42 07-25-2008, 12:51 AM I have started engine with a gasoline soaked rag in the air filter chamber and changed out the timing chain & sprockets, as posted previously in this thread. Also started on gasoline soaked rag after changing out timing chain, just can't get fuel through injectors. I used a noid light tonight and it did not light up at all while cranking. First time ever used one, does this mean no power at all to injectors? I thought I would get a steady "light up" or if functioning properly an intermittent light, but got nothing at all. Any ideas? sherman42 08-06-2008, 03:36 AM The car is fixed. Since my last post on 7-24 I had taken Ignition Control Module off & had it tested. Tested good. This past Sunday I was checking voltage on each injector during crank/no start , removing 1 injector "plug in" at a time and testing. When I pulled off #4 injector plug and told my wife to crank it the car started. Put plug in back on & it immediately killed engine. Would not start again with plug on - took it off again and started. Bad injector. I am not very knowledgable on auto mechanics & did not realize 1 bad injector could kill the other 5 also. Changed injector tonight and the car is fixed. Thanks for the replies maxwedge. CoolasIce 08-21-2008, 09:04 PM Very good. So the bad injector was shorting the injector drive circuit?:confused: sherman42 08-23-2008, 03:59 AM Very good. So the bad injector was shorting the injector drive circuit?:confused: It now makes sense to me that the noid light test showed nothing. After putting in new injector I did the noid light test again (just to satisfy my curiosity about what the noid light should do) and it did the flashing light as I believe it should. So, yes , I believe that injector was shorted out and it caused all injectors to have a dead circuit and therefore no pulse. Honestly, I really don't quite understand that . I don't have very good grasp on auto electronic systems. I felt very fortunate to have blundered on to what was causing the problem and am thankful I was able to fix it. Hope these posts may help someone else if they ever have a similar problem. maxwedge 08-23-2008, 09:50 AM The bad injector pulled the current from the others by having to little resistance. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
