I have checked each injector with a noid and they all have pulse
is this what you mean or can I somehow jump each injector another way. I could understand if a wire was bad going to the computer but I don't see all of the wires being faulty. Possible I guess.

 

Just some thoughts for you and George.

Looking at your old posts I see you bought this vehicle as a fixer and have potentially never seen it run. I also see you replaced the steering column earlier this year. I wonder if it has a Passlock problem. This would let the injectors pulse while cranking but engine would die as soon as it starts. Is this the case? Did you do the Passlock learn procedure after changing the column? The Passlock sensor is inside the steering column.

Also how sure are you about the quality of the fuel in the tank?

If you do the attached Passlock auto learn procedure, do it exactly. And put a decent battery charger on during the learning procedure. Whatever scanner you use, will need to read/clear B-series (body) codes. Car Diagnostic Pro is a bluetooth app that will do that.

 

Thanks for your input. I did post about steering column replacement. And no I did not do it passport relearn. It has been at another shade tree mechanic place and he can't figure it out. But this post George and I are talking about is a no start problem on my 2000 zr2. It's been my daily driver for years and this is the first time it has let me down..any ideas? New fuel pump filter and spider assembly but no fuel from the injector. I guess the 99 will be next. Thanks

 

Sorry to butt in. George will continue to give you good advice.

 

I am going to run with one of Les' ideas. Are you sure that the fuel quality in your tank is ok?

If the fuel is good then this is how you see if the injectors are injecting fuel properly and uniformly:



You use this pulse box in conjunction with your fuel pressure gauge as shown here:

Lesmyer got me thinking about the passlock. I tried this some time back but only tried once. I went through the process three different times and the third try was a winner. It fired off and ran like a champion. Well I am well versed in pulling intakes and injectors. Thanks a million George for being patient and staying in there with me. Also a big thanks to Les. Merry Christmas 🎅

 

Glad you’re fixed up.

George

 

Thanks for letting us know. Merry Christmas!
