I dont believe so...fuel pressure is fuel pressure... the injectors should see a certian range to operate correctly.... but what do I know I'm running smaller than stock Generation 3 injectors that spray more than stock at the pressure the trucks pushing and actuall see better mileage ....when it runs...

 

He should be seeing 49 psi.

 

ok than its mine that should be at 40psi...I know the 96-97 had different pressure than the 98-01..

 

Wow. Sounds like me. I bought my truck a year and a half ago from the husband's friend. I haven't gotten 2000 miles on it yet. Had it sitting for 6 months with transmission solenoid issues and burnt up bands and drum. Everytime I get it running, something else goes bad. LOL! Its running 49psi, for sure. That's a relief I guess.. I'm a little worried about the fact that its not raising with throttle though.

 

I've had the same solenoid issues...lol day after I bought it the truck stopped shifting... one issue after another ..7,000 miles in almost 5 years now and cost me about $4,000 to get there...

 

Costs run up fast when you get anywhere near the transmission! =/ I think I spent 400 for all the solenoids, plus fluid, filters.. Which one ended up being the wrong one. So, more fluid, another filter, and the right one.. Months later it went in and cost me almost 700 for the drum and bands.. I hope I don't have to see that side of the truck again. In that short year and a half though, its cost me a new power steering pump, fan clutch and fan, tps, wheel bearings, u joints, track bar, (Death wobble threw my tire into the front of an 2012 equinox....) Water pump, and ball joints. That's just what I remember.. =/ Some day it will be all brand new. LOL.

 

Fuel pressure is good.



She....


It is an electrically operated pump in the tank. Unlike an engine driven mechanical pump, it will not increase with speed of the engine. It does not know or care how fast engine is turning.

 

Thank you for clearing that one off my list! I'll try to get in there and test the water temp and check this plenum tomorrow. Maybe I can rule them out. Thanks again guys!

 

Problem Solved. Went up to ask the mechanic his opinions, He said Vacuum leak, so I came home and was preparing to test that, when my husband got in there and wiggled some wires.. One of the Spark plug wires he wiggled caused it to rev. After he got the **** shocked out of him, we found the wire had burnt and grounded out. I have wires on hand. Test drove it, and it runs great! Oh, the water temp is 174 when hot. Apparently has nothing to do with this issue, but yeah. Plenum is also fine. Thanks!!

 

Glad you got that problem fixed. Shame about the shock thing! Hope he's OK. (I usually bang my head on hood!)
