Okay,
I'll hope i understand you:
Testing voltage at the injectors: Pink wire connected to ground: there are 12 volts.
Testlight while cranking: Testlight between pink wire and the "black-lined-wires" or between the black wires and the battery positve connector? I've found this discrpition...
Okay,
I noticed a few strange things: i tried to generate some trouble codes.
Unplug CKP: trouble code
Unplug MAF-Sensor: trouble code
Unplug CAM-Sensor: no trouble code
Unplug TPS: no trouble code
Unplug ECT: trouble code
When i took a look at the "live data" from my chevy, my...
Hi east302,
There are no trouble codes stored.
The relearn procedure is done since I've changed the ckp and the chevy runs well.
TPS sensor voltage is not able to read with my scan program. The ECT display the correct temperature.
I've tested the blk wires with a test light and the positive...
Okay,
New injectors don't fix the problem....no fuel in the engine. All spark plugs are dry....:(
Fuel pressure is okay, good spark, etc...but no fuel at the injectors
What can i do...???
Best regards

Hey Guys,
I'm back from Greece (Crete) and i hace the new spider-injector...;) I'll hope the weather is on sunday okay so i can fix my chevy (no garage).
Best regards
Servus,
I've replaced the distributor an cap...the chevy runs very good a few months...until it dies..:(
The fuel is okay...checked.
Every sensor is working correct. my scanner-program shows it to me.
@east302: yes, the ses light goes on and stays on when the ignition is on. When i'm...
Hi east302,
Cylinder 1 and 4 are wet..the other are dry.
The history shows nothing about misfiring....everything else, but not this.
But i remember one thing: I've changed the spark plugs 3 or 4 months ago...and it looks like they are running with poor gas (not rich enough...sorry, my english...
So,
It's all tested:
- there is 12V on each injector
- 0.78V at the TPS
- the EGR looks pretty good (seems to be new)
- teh ECT reports the correct temperature
Not all plugs are wet...only two of them. The other six are dry....
I've spark on everthy cylinder, fuel presssure, etc..is okay.
My OBD-Software can read the ECT and TPS data...everything is fine.
I've never done a compression test...i think it's not necessary. The car runs fine and dies wirhout any signs of no compression or something else. The timing chain...

Hi Nathan,
I do not know what else it could be..:(
I've spark, Battery is in good condition, the car cranks, the fuel pressure is ok...everything i fine....but no fuel at the spark plugs and no trouble codes. The fuel reaches the schrader valve with the right pressure...:(
In germany is the...
Okay....
All ground wires are in good condition.
I think it's better to install a new spider assembly....
What's the difference between cpfi and mpfi? is it easy to convert it?
I've seen, there are different diameter available...5mm and 6,5mm. My 8digit at the vin-code is an "R"...so i think...
Okay,
I've doublechecked the spark plugs after some cranking the engine.....6 of them are dry...no fuel....:(
The fuel filter is new...changed it last month....;)
Ignition coil, cap and rotor are from delco.
Well, i can improve a ground wire an test it..
Hi Nathan,
Thank you for your reply..;)
Before this happend, the chevy runs very well...okay, sometimes rough idle (when it was very warm) and a little bit stumbling. but when i remember, the car ws often hard to start when the engine was hot....:(
I don't have any security light and it's the...
Hey Guys,
I'm Matthias from Bamberg, Germany. I've an 96 Tahoe (350 Vortec TBI) and a real big problem:
My car died three weeks ago while i'm driving (it was like, someone cut off the ignition) and won't start again. Nobdy in Bavaria and Germany knows why.....:(
