if you installed a tensioner like the used one in the pic you need to throw it away and get the correct (hydraulic) one. The mechanical ones work with non-VVT engines. You must have got a NOS kit.

 

But would it keep it from Starting ? or just create problems down the road

 

Let me ask one more question.
When you say it won't start. Are you saying the engine doesn't spin over ?

 

No the engine turns over fine and smooth. but I have noticed if it sits for some time and you go turn the key for just an instance it seems it wants to start then thats it it just turns over fine I have plenty of fuel at the fuel rail it blows out all over the place but how do I check if its coming out of the injectors ?

 

This sounds like this may be the problem. There should be a Schrader valve in the tester, so it's supposed to hold. But 90 PSI is extremely low. The auto parts stores have the testers in their "loaner" program. That is, you buy it, and have, I think 90 days to return it for a full refund. It's worth a try.

A healthy ecotec would be 140-180 PSI.

 

That low a pressure leads me to think the chain is off a tooth or 2, especially if it is all 4.

BTW; you should only have to momentarily hit "start" the computer will shut the starter off either time out or started. No need to hold the key.

 

His compression tester might be off.
Yes, 90 psi is low by his gauge. But is it ?
No start can also mean, no spark.
I think it's time to pull the front cover. Take off the chains. Pull the plugs and rotate the engine back to #1 and start all over.

 

First, I would try another compression tester. If still low compression, a leak down test. If it's leaking into the crankcase, there's a problem with the piston/rings/cylinder wall. If it's leaking into the intake or exhaust, the timing is probably off.

Cat Man, I think he said he's got spark.

Yeah I get lazy at times.
Thought people could fill me in if I missed something.
Just to many things happening here for the problem at hand.
If the chains are installed correctly and the engine has low(?) mileage, compression should be higher than 90.
The OP says he has "Fire" but to start.
What does that mean ?
