Fuel systems
[align=left]I have a 94 Chevy s-10 Blazer. The vehicle has spark and is getting fuel up to the inlet and return line clip, but does not seem to be despensing through the poppet nozzels because the vehicle will not start unless injected with starter fluid. Have any suggestions??
Thanx,
Ricky

RE: Fuel systems
What is the engine code on the VIN(8th digit)? I assume it is W when you say there are more than one injector.
If it is, start by check the ECM1 fuse. then go to the injectors and check for Ign voltage on the red and white wires of the injectors. If you do, then next step will require you to get a noid light to check the output from the ECM. They are only about $20 for a set of them. http://www.toolsource.com/noid-lite-...t-p-89901.html
Unplug the injector and put the noid light in and crank. If it flashes, then you are looking at a bad injector. If it doesn't flash, you either have 2 broken wires...1 for each injector, or a faulty ECM
