Symptom - 2nd vehicle, was running fine 2 months ago. I have been traveling a lot and did not drive it at all. Now it won't start. It gives one good rev and then dies. Sounds fine for the first 2 seconds.
It's New England and very rainy the past several weeks. I figured if it turned over enough it would eventually start. No luck.
I had a problem with it last year and they cleaned the butterfly valvle controlling air intake to the manifold (think I got that right) and felt that a large carbon build-up was causing grief to the TPS and ECM. It came back running fine and stayed that way until it sat for so long.
I took it to an Isuzu dealer who wants to start by replacing the throttle assembly for $1000 and said maybe the ECM as well, for another $1000. I'm not buying their diagnosis.
Why did it run fine before that? Nothing has changed except sitting. I will note that the intake manifold seemed to have a lot of carbon again, and the plugs were really fouled. I changed them, but it really seems like it chokes for two seconds and then opens up to run, but dies.
Thoughts? Can I get it running long enough to sell it?!
Thanks!
