Guest 1959olds Posted October 7, 2004 Share Posted October 7, 2004 FUEL- start with looking at any fuel filters, then fuel pump. Link to comment Share on other sites More sharing options...
dav Posted October 7, 2004 Author Share Posted October 7, 2004 did fuel filter no change..do you know if fuel pump is in tank Link to comment Share on other sites More sharing options...
Sgt Art Posted October 8, 2004 Share Posted October 8, 2004 do you know if fuel pump is in tank It is.I'm lost on EFI cars, and work for a GM dealership! I would suggest paying the diagnostic fee which is normally one hour labor. That will be cheaper than throwing a bunch of parts at the problem, hit or miss and maybe still not finding the problem. Sometimes it's really simply stuff but it could cost you a couple of hundred bucks trying to solve it yourself not to mention time involved.

dav Posted October 8, 2004 Author Share Posted October 8, 2004 probably best advise.... thanks Link to comment Share on other sites More sharing options...
86 2dr.ltd Posted October 11, 2004 Share Posted October 11, 2004 That is best advise. Sounds like low fuel pressure. I had this symptom on my 91 Regal last year, same engine L27-L Tuned Port 3800. I had internally rusted fuel lines that broke up and clogged the pressure regulator. Thats how I discovered it. I pulled the snap ring on the presure reg and took it out and it was chalk full. You need to depressurize the system first. Find the fuel pump fuse or relay and pull it out. Start and run engine till it dies. My injectors and rails were pluged as well. You DONT need to send injectors out to be cleaned or buy new ones.Do you do your own work ? Let me know if this is the problem after they diagnose it. I'll try to remember to come back, I dont stop in much anymore, dont know why ? Guess because Im not currently working on my Older Olds. Im just working on my old Olds Link to comment Share on other sites More sharing options...
dav Posted October 12, 2004 Author Share Posted October 12, 2004 coil pac and module ..they said the key was the fact that in gear it sputtered but in neutral it would rev up fine ..no load when not in gear..running fine again ..can't believe the gas mileage this car gets Link to comment Share on other sites More sharing options...
Sgt Art Posted October 12, 2004 Share Posted October 12, 2004 Great! I'm guessing you took it into the shop and let the pro's fix it? Link to comment Share on other sites More sharing options...
86 2dr.ltd Posted October 13, 2004 Share Posted October 13, 2004 same deal with my pluged injectors, under load it would skip.In neutural it would rev fine. Glad you got it fixed without replaceing lots of stuff that did not fix it. Link to comment Share on other sites More sharing options...
dav Posted October 14, 2004 Author Share Posted October 14, 2004 pros diagnoised it wanted $300 to fix ..went to u pull it yard $16 later I'm on the road..167k miles I'm on borrowed time used part is sufficent Link to comment Share on other sites More sharing options...
86 2dr.ltd Posted October 16, 2004 Share Posted October 16, 2004 Borrowed time, I dont know. I had a L27 Regal with 244,000 and it ran great. I really do wish I had of kept it.I traded on spur of the moment. Now I have a 90 Regency with the LN3-C that has 314,000 and runs great too. I agree about used parts though.
