Re: LT5 miss at all speeds

Nope, still chasing it. Haven't had a chance to get back to it because the Blazer decided it liked to shift into 4WD all by itself so I've been playing with that with my free time. Looks like a TCCM...

Re: LT5 miss at all speeds

With the schematic/diagram I can trace the circuit inside the ECM to see what controls the injector and if I find that the ECM is causing my problem I can hopefully determine if the internal circuit...

Re: LT5 miss at all speeds

I got the swivel socket from NAPA and it works great getting the back two plugs out. It is easy with a swivel. Hope the plug is the problem.

I'm still chasing gremlins in mine. When I shoot back...

Re: LT5 miss at all speeds

I did read it and I thought I had picked the correct size pin to insert into the socket but obviously I must not have. Hopefully this will fix this problem and I can move on. Thanks to all for all...

Re: LT5 miss at all speeds

thanks 'Crabs, I'm hoping to get back on it this weekend and see if I can't get her back on the road, missing all this good weather we are having up in the Pacific N'West. I gotta keep the chores at...

Re: LT5 miss at all speeds

Ok, the saga continues. First, I believe I have found the problem but ran out of time last night to fully verify. Looks like I have a bad connection at the ECM connector, probably a pushed back...

Re: LT5 miss at all speeds

I have an unmodified 90 and I have the 90 SM. I went to the library and got a diagram for the primary circuit which shows the primary wiring and the "splice S127" i believe. I also have the LT5 Fuel...

Re: LT5 miss at all speeds

Hi Paul, I also talked to Jon this morning and he said that you had called him. Thank you. He was helpful and gave me the same information. I find it hard to believe that the injector would be bad...

Re: LT5 miss at all speeds

Re: LT5 miss at all speeds

got the new FIC injectors in. So far so good. They look high quality and I think they will do the trick. Ordered them on Tues, got them Weds. Easy install. I released the old injectors from the fuel...

Re: LT5 miss at all speeds

Ok everyone, Got the plenum off with no problem. Way easier then what I had imagined with all the good info on the Registry. Took about 40 minutes and broke nothing. However, I tried a suggested...

Re: LT5 miss at all speeds

Looks like I'm going to go with the injectors from FIC. Can anyone suggest which brand of coils I should go with and where to get them.

thanks again everyone,

Re: LT5 miss at all speeds

thanks everyone for your inputs. Looks like I will be going under the plenum for the first time. Should be a good time....... Looking forward to getting her running back the way she should.
