2000 Chevy S-10 fuel injectors

Is it the power side or the pulsing ground side that's missing?
Do you have spark?
Does your check engine light come on for bulb check when you turn the key on?

If it's a Vortec, how did you conclude that they weren't spraying?

did you recently work on this vehicle, if so what exactly did u do...

Well the truck has been sitting for 3 yrs before I bought it. I replaced the gas tank fuel pump injectors and crank sensor. Just put it all back together now its spitting and shuddering

I was told to pull it apart and turn key to check the injectors. Also it will run with starting fluid.

What's your fuel pressure?

Its pushing in the 55 range..

That's not enough fuel pressure. 55 is about the bare minimum to run and sometimes not enough. 60 to 66 is the spec and it needs every bit of it.

if it runs on starting fluid, it sounds like a definate fuel problem.... i agree, check fuel pressure... if its low, remove fuel filter... you should beable to blow through it freely... if not, then its clogged badly, and needs to be replaced... recheck fuel pressure... it should be in the 55-60 range

I don't think your not going to see 100 pounds out of this pump even dead headed. Peak will probably be about 70 to 75 dead headed. I suspect yours isn't even hitting 60.

after some research i discovered that this engines fuel pressure should be 55-60psi....

No, the spec is Key On Engine Off 60-66 psi


and it was posted already.

I change all and completely forgot the filter. I'm going to go pull it right now and check it and prolly just replace it tomorrow. Hey I really want to thank you guys a lot. This is an amazing site. Thanks again guy. I'll let u know what I find.

Just pulled the filter took everything I had to blow through it. Pick up one in the morn see what happens. Its at 60 on pressure.

Update.. Its running but very choppy. I've put a fuel pump,injectors,filter,and plugs. Everything is set right as far as pressures and wires. Any ideas on why its running so rough. Anything else I've overlooked.. Thanks

Any check engine light now?

Yes lights on. Not sure if I can get a scanner or get it to a scanner.

That's where you have to start

Evap control system pressure sensor low.. Is the code I got.

When did you read that code?
