To all,
this truck has been starting hard for about a year. By hard I mean a long cranking time and a lot of spiting and sputtering until all 8 are runing.
The truck will start well after setting 3 or 4 days. We have new plugs, wire's
cap and rotor. My thought was the coolant temp sensor however i can't seem to get a good reading from the paperwork I have as to what restance at what
temp it should be. I am recving 5 volts DC at the tmp probe from the ECU.
A conversation with A new 109 owner sugests maybe leaking fuel injectors.
A test has the fuel rail presure droping from 38 psi to 22 psi in under 5 min.
This would ind that we may have bad injectors. Or is there a check valve in
the return line that chould cause this trouble.
If new injcctors are needed where do I order them from
Thanks
