1995 Paaaaathy

[Lunartic]

Hi there guys. Just sometimes when I start the truck it seems to run on 4/5 cyls. then I shut it off. Then I start it up again and it's good. There's no codes been stored, and all vac lines have been checked. A little while ago it did the same thing and codes reported injector circuit. Ok, but when I restart it>>> trouble light goes away and runs like a charm>>> like there was not problem at all. And last year ECU reported failed injector.I never changed nothing as I checked all injectors and all were good. Truck is still running ok with no loss in mpg only when it starts like crap. Its there for 2/3 starts sometimes.

If it's been giving you injector error codes, why not troubleshoot the injectors and wiring? They can test good but still plug up or misfire every now and then. Try finding some junkyard injectors and swapping them out, perhaps.

Can you clean out old injectors with air pressure and cleaner or are they a sealed unit?

I've never found injectors very hard to remove. Just have to eliminate fuel pressure first or you spew gas all over the engine.

[Lunartic]

Are all six injectors generic? And are 1994 and 1993 injectors the same? Can they be used in a 95?

[k9sar]

I think all the VG30E's use the same injectors. 94's are the same as 95's

Thanks for the help again. I was looking through the vac lines and came across the line at the firewall centre, a black tube that is connected to the intake and connected to the fuel line rail. I took it off and the end of the hose that is plugged on to the intake was pluggedfull of BLACK @%!@. Well I cleaned it out with a small drill bit and now it's a good...
