Hi!
I have a 90' Chevy Lumina APV 3.1L V6 with TBI( Throttle Body Injection).
I start having a problem starting my van when it was hot. In the morning was good after 20 minutes drive did not start. fuel pressure is good ,new pump,new fuel filter , new pressure regulator. now wont start at all. injectors checks out good . I did a noid test and there is no power going to the injectors. Im thinking the ECM unit go bad. any ide guys what else can be?
Thanks for your times.!

 

Hi,
I hope someone makes a comment on this post. I own a 1994 Chvy. Lumina Van, 6 cyl. 3.1.
It has been running so well over the past years. All the sudden it just doesn't start. Batter kicks it over (bought battery last year 5 yr, warranty). It wants to start but won't kick over.
-First the mechanic tried Fuel pump, says thats good
-then he changed a module
-then he told me I needed a pick-up coil for distritributer, I bought and he installed still won't start.

It has been 5 days, he has the schematics for the van, but still can't seem to locate the problem. I really can't afford much for of this, money mounting up as he is trying to find the problem. He has done work for me before, so I don't think he is trying to con me or anything.
If anyone has an idea of what this could be I would appreciate it greatly. We did put new sparkplugs and wires in, nothing,
Thanks!
