I just completed a head gasket replacement (had head sent out for a complete valve job as well as machined flat) on a 98 Neon SOHC engine. The re-installation went fairly smooth. After getting everything back in place the Engine cranks strong upon turning the ignition key, but I am unable to get it started. I removed fuel injectors and had them cleaned. Fuel pump is supplying fuel to Rail.

I Ohmed out the Main Relays (all checked "good").
Verified Primary & Secondary Resistances were correct on Ignition Coil.
Voltage is present at center terminal of Ignition Coil Plug.

How does one verify if the fuel injectors are actually being activated while the engine cranks ? Are there measurable vlotages that should be present ?


Thanks in advance for any/all suggestions.

:cool:

Not sure what the voltages you should see on the fuel injectors. Can be found in the service manual though.
Have you checked fuel pressure? Do you even hear the fuel pump when you turn the key? Anything spew out fo the shrader valve when you relieve the pressure?

Injectors should read like 14 volts if my memory serves me correct... I cant remember though

just un hook the the fuel line or unplug the injectors and turn the key over honestly ( u may have to pump the gas not sure ) ( i know this sounds stupid but) if gas comes out ur injectors are fine if not then there u go!
